Item Box

Item Boxes (アイテムボックス), also referred to as Video Monitors, Monitors, Item Capsules and TVs, are common objects in the Sonic the Hedgehog series. First appearing in Sonic the Hedgehog (1991), Item Boxes contain various kinds of power-ups or bonuses which can be used by the player. Placed on the ground, mid-air or even hidden in different places in Zones, the player can open them with attacks to obtain power-ups.

Description
Item Boxes are usually placed on the ground, but these containers are also set to float on the mid-air or they are placed in hidden areas or Zone's environment like palmtrees. Item Boxes can also found floating in the mid-air. Item Boxes can be break open by attacking them, usually by Spin Jumping on them, performing Spin Attack or any other attack. Homing Attack will target Item Boxes the same way as it will target enemies, and some chasms can be crossed by using Homing Attacks on a string of floating Item Boxes. Also, certain playable characters can use weapons to break Item Boxes. In some games, if the player hits a floating Item Boxes from below, it will make it drop to the ground where it can be broken easily. If the player holds the jump button while destroying a Monitor, the bounce back is the same as that of a Badnik; that is, the longer the distance the player fell onto the monitor, the higher he will bounce back up. The player can land normally on the Item Box, if the playable character does not perform Spin Attack or any other variation. Since Sonic Advance 2, Item Boxes can be open by simply touching them in certain games. After breaking it open, the icon that is seen in the Item Box will pop out and the player receives the power-up or item.

Items in these containers are variable in each game. Items can give Ring, time or score bonuses (Super Rings), are protective against hazards and enemies (Shield and Invincibility), affect the player's speed (Power Sneakers and Speed Downs), give different upgrades or weapons (Rocket Shoes and Mines), recover energy (Fly Charge and Damage Recover), grant extra lives or even cause damage to the player instead of helping them (Eggman Marks). Some items can't be used normally in the game instead of using Debug Mode such as S items.

The appearance of Item Boxes have changed on several occasions. In the early games of the series, Item Boxes took the form of grey, rectangular cubic computer Monitors with the icon of the power-up contained inside shown on the flickering screen. Even though they have got replaced in later games, Monitors have made appearances in recent games, mostly in those which are 2.5D, such as Sonic the Hedgehog 4 (both episodes) and Classic Sonic's stages in Sonic Generations. Since Sonic Adventure, Item Boxes were redesigned to look more like glass capsules.

Variously, Item Boxes have aid base beneath them or containers just float in the mid-air. In recent games such as Sonic Lost World, Item Boxes' appearance have been simplified with glass dome and red top/bottom covers.

Usage of Item Boxes has varied considerably through the series, being present in most 2D as well as 3D titles until Sonic Unleashed, in which they were replaced with different methods of getting power-ups such as floating Super Rings and 1-Ups, which could be obtained by simply touching them. Despite this, Item Boxes continue appearing regularly through the games, specially those that do not make use of the "Boost" technique.

Sonic the Hedgehog (1991)
Item Boxes first appear in the original 16-bit version of Sonic the Hedgehog, where they are called Video Monitors. The Video Monitors are presented as simple, grey cubic televisions with a static screen and an icon of the power-up the monitor contains. This game presented for the first time the Video Monitor items Super Rings, Shields, Power Sneakers, One-Ups and Invincibility. Debug mode also features a non-functional Monitor with an icon of Dr. Robotnik's head, similar to the Eggman Mark from later titles.

Monitors also appear in the 8-bit version of the game with same name, where they are also called Video Monitors in American instruction manuals and have all the power-ups from its 16-bit counterpart. The game also introduces the Arrow Monitors, which replace the Star Posts as checkpoints, and Continue Monitors (represented with "CONT" written on them), which Sonic can find in the Special Stages of said game, granting players a new possibility of finishing the game once they have lost all their lives, allowing them to start in the Zone they were before.

Sonic the Hedgehog 2
In the 16-bit version of Sonic the Hedgehog 2, the Video Monitors have a similar appearance and the same power-ups as the first game. As well, the player can hit a Monitor suspended in the air from below causing to drop to the ground, but it can also crush the player. In the multiplayer mode (where they are referred to as Item Boxes) of the game, all Monitors are Random and also features the exclusive Teleportation and Robotnik monitor power-ups (which the latter actually first appeared as an inoperable object from Debug Mode in the original Sonic the Hedgehog). In Options, the player can toggle the behavior of the Random Monitors to either grant all power-ups previously mentioned or grant Teleporation only. In multiplayer mode, each of players can win the round depending on how many Monitors are broken. Knuckles the Echidna in Sonic the Hedgehog 2 features identical Monitor power-ups as well.

In the 8-bit version of the game with same name, Item Boxes appear more generally and are called Monitors. Monitors here have the same power-ups as in the 16-bit version of the game, excluding the Shield. The Master System version contains a single Power Sneakers item in Aqua Lake Zone Act 2, which is removed and replaced with a Super Ring in the Game Gear version. Unlike the previous 8-bit game, this version does not feature Arrow or Continue Monitors; though, the game has unused data and sprites for both items. This version also has data for an unused Monitor power-up with a grey shoe icon on it.

Sonic the Hedgehog CD
In Sonic the Hedgehog CD, Monitors appear normally and retain all the power-ups from the original Sonic the Hedgehog, with the addition of "S", a new Monitor which would grant the player the Invincibility and Power Sneakers items at the same time, and only appearing in Debug Mode. In the game's Special Stages, if the player blows up one of UFOs, the player can receive Monitor power-ups like Super Rings or Power Sneakers.

This game also features a non-functional Monitor with a blue Ring icon on it, similar to the Hyper Ring power-up from later titles.

Sonic Chaos
In Sonic Chaos, Video Monitors appear generally and have all the power-ups from the previous titles, barring the Shield. The game also introduces the Rocket Shoes power-up, which can only be used by Sonic. The game does not feature Arrow Monitors. In some Special Stages, a Time Stop monitor can be found that will pause the timer for a while.

Sonic the Hedgehog Spinball
In 8-bit version of Sonic the Hedgehog Spinball, Item Boxes are featured as hidden objects in small chamber in the corners of each stage. These items are usually extra lives, continues and certain variants with the Japanese kanji for "look" (見る). These variants are hints to secret codes that can be used in the game.

Sonic the Hedgehog 3 & Knuckles
In Sonic the Hedgehog 3, Sonic & Knuckles and Sonic the Hedgehog 3 & Knuckles, monitors contain all the power-ups from previous games, excluding the normal Shield. In this game however, monitors are designed as a light grey device instead of general grey cube. Monitors can pop out if the Goal plate falls down on a certain spot.

Despite having no normal shield, the game introduces three new shields Monitor power-ups, which include the Flame Shield, Water Shield and Lightning Shield. It also features the return of the "S" Monitor power-up in Debug mode, which grants a Super/Hyper transformation this time. When the player enters the first and second Bonus Stages, these items (Minus the "S" item) can be collected from multiple colored floating orbs. All three games also features the return of the Eggman Mark (previously known as simply "Robotnik") from Sonic the Hedgehog 2, in Single Player mode, which inflicts harm on the player.

The Competition Mode features different kinds of power-ups, which include Super Rings and Power Sneakers. Competition Mode does not feature monitors, as the power-ups are collected from small bubbles.

Sonic Drift
Sonic Drift features two different types of Monitors on the racing tracks. Red monitors give a burst of speed (similar to the Power Sneakers item from the platform titles) and blue monitors give Invincibility, with a variation of Green Hills Zone's music from the 8-bit version of Sonic the Hedgehog 2.

Sonic Triple Trouble
In Sonic the Hedgehog Triple Trouble, the Monitors' appearance and featured power-ups are the same from earlier games, including the Rocket Shoes and Arrow Monitors but excluding the Shield.

The last two can only be used by Sonic. To enter Special Stages, the player has to find emerald monitors which are hidden in every first and second Acts of Zones and break them while holding fifty Rings. In Special Stages with platforming, there are also the Time Bonus which extends the time the player can spend in the Special Stages.

Sonic Drift 2
Sonic Drift 2 features differently colored Monitors lying on the tracks. Like in Sonic Drift, the red ones grant a boost in speed and the blue ones makes the racer invulnerable. There is also two new types of Monitors: the yellow ones makes the racer jump and the black ones allows the racer to set up Mines.

The Red Shield is like the Flame Shield from Sonic the Hedgehog 3 & Knuckles, protecting Sonic from fire-based damage, although without the midair dash, and the Gold Shield, that enables the Blast Attack. In addition to this, the Flickies that follow Sonic also get a small version of these shields whenever Sonic is wearing one.

Some of these Item Boxes are set on the ground or floating in the mid-air. If the player is using Sonic, he can target them with his Homing Attack.

Sonic Adventure features the basic power-ups such as Power Sneakers, Invincibility, Shield, the Magnetic Shield and extra life. However the Super Ring Item Boxes are given a new concept where they give different sets of Rings from five to ten.

Tails can also throws Item Boxes as a part of his Dummy Ring-related attacks. In this game, after collecting a power-up from an Item Box, its item will not respawn after the player loses a life, meaning the Item Box is left empty when the player returns to it after losing a life.

In the Wii U version, many of the mentioned power-ups are rewarded by completing certain missions in Zones, finding random drops on the map of the Lost Hex, or being gifted by other players through Miiverse. Item Boxes cannot be homing attacked in the Wii U version, but can be locked on in the 3DS version.

In Competition Mode, Monitors contain Random Items, including Player Swap which swaps places between both players.

Sonic Forces: Speed Battle
In Sonic Forces: Speed Battle, the Item Boxes retain the same appearance they had in Sonic Lost World. In gameplay, Item Boxes will regenerate a second after they have been obtained by a player. Every playable character has their own unique set of power-up Items they can obtain at random from Item Boxes, though all characters can obtain the Shield Item. Unlike in previous games, obtaining a power-up from Item Boxes stores it in one of the three slots at the bottom of the screen. As such, the player is able to store up to three Items at a time. These Items can then be used by touching their respective icon.

Floating Item Boxes
Floating Item Boxes or simply Balloons are Item Box variants in the form of red balloons with white and blue circles containing a star on them.

Items
In the Competition mode of Sonic the Hedgehog 3 and Sonic the Hedgehog 3 & Knuckles, power-ups which were not contained in Item Boxes were introduced. Instead they could be collected simply by touching them. Such power-ups when first introduced were initially held inside small floating bubbles during Competition Mode, allowing faster usage of them during races.

Games like Sonic Unleashed, Colors and Generations would later pick up this concept for more classic and common power-ups, but without anything encapsulating them.

Key: S3&K = Sonic the Hedgehog 3 & Knuckles (Competition Mode), SU = Sonic Unleashed, SC = Sonic Colors, SG = Sonic Generations, SLW = Sonic Lost World

Stay Sonic
Item Boxes, referred to as simply PCs, have been given some sort of a back story in Stay Sonic. As planning to use his Retro Orbital Chaos Compressor to contain all the negative energy of the planet within six emeralds, Doctor Ovi Kintobor required a seventh gem to stabilize the process, but could not locate one himself. To broaden his search, he set up a network of monitors across the entire planet that served as an interlinked communications system, allowing the people of Mobius to pass along any information to him that they could about the final emerald's potential whereabouts.

Sonic the Comic
Monitors also appear in Fleetway's Sonic the Comic, as sharing the same kind of background from Stay Sonic. The another one of Kintobor's creations was an artificial duplicate of Sonic known as an Extra Life, which was stored within one of the planet's many monitors.

Unfortunately, the Extra Life was never needed and so remained trapped in its monitor for years, slowly becoming corrupted and bent on revenge, until it duped Tails into freeing it by pretending to be the real Sonic. After besmirching Sonic's name by causing chaos in the Emerald Hill Zone, the Extra Life was sucked back into its monitor by Tails, and the box was then kicked into space by the real Sonic.

Archie Comics
In the Archie Comics's Sonic the Hedgehog comics and its spin-offs, monitors or item boxes hasn't been seen until one item box has been seen to being developed in Sonic Universe #38, which has been created by Hope Kintobor and possibly G.U.N. It was originally invented to be device to help E-123 Omega during combat battles.

However Snively teleported himself to the GUN laboratory and tries pleasing Hope being part of their family and rule the world with him and Regina. Hope disagrees to join him after the conversation and activates the item box which has Flame Shield in it, forces the Snively to leave him and activates the alarm. Snively leaves the place and Hope has been seen crying alone with Flame Shield still on it at the laboratory where later Omega finds him. In the Post-Super Genesis Wave timeline, the Item Box has appeared once again, this time in the Soumerca Egg Army's base. Where they used it to store the Master Emerald's shards. In this continuity, it resembles both the designs of Sonic the Hedgehog (2006) and Sonic Colors.

Trivia

 * In the classic Sonic games, there is a brief delay between the moments where player breaks the Item Box and when the player receives the power-up. For example, if the player gets a Shield or Invincibility item, it is still possible for the player to take damage before the power-up's effect is received.
 * Monitors from Sonic the Hedgehog (1991), Sonic the Hedgehog 2 and Sonic the Hedgehog CD are based on the basic CRT monitors, while Monitors in Sonic the Hedgehog 3 & Knuckles bear resemblance to Apple's Macintosh from the mid-1980's. Later on, Monitors in Sonic the Hedgehog 4 seem to be loosely based on modern flat-panel LCD TV, while Sonic Generations brings back the original CRT design, albeit with a more modernized look. Monitors in Sonic Forces use the same CRT design from Sonic Generations.
 * Sonic the Hedgehog 2 and Sonic the Hedgehog 3 & Knuckles are the only games where the player is able to get crushed by the fallen Monitor. Normally in games such as Sonic the Hedgehog (1991) and Sonic CD, Monitors usually are seen bouncing on Sonic's head and falling simply to the ground without damaging him or simply being broken open in other games.
 * In Sonic the Hedgehog 4: Episode I, Sonic does not get crushed by a fallen Monitor, but instead he sinks through the ground and gets stuck. This is regular in-game glitch, that is possible to happen often in corner sections.
 * In Sonic Generations (3DS), Monitors simply bounce repeatedly on Sonic's head until he moves out of the way. Jumping straight underneath them will not break them.
 * In earlier games, when the player has both Sonic and Tails, Tails couldn't destroy Monitors as his own. This was although possible in the Simon Wai and Nick Arcade prototypes of Sonic the Hedgehog 2.
 * There are certain Monitors at above sections that can't be reached with Sonic or Tails in Sonic the Hedgehog 2. However, with lock-on technology of Knuckles in Sonic the Hedgehog 2, Knuckles can reach these sections that have those Monitors.
 * Although Item Boxes don't appear at Competition Mode of Sonic the Hedgehog 3, one Item Box can be seen at the options menu of Competition Mode, as items can be set on and off.
 * The same way, Tails Adventure doesn't feature Item Boxes, although one can be seen upper left corner of gameplay hud, showing the amount of the rings that player has.
 * City Escape has advertisements of different things in Sonic Adventure 2 as one of them being Item Boxes with ten Rings and various other power-ups.
 * In Super Smash Bros. Brawl, an extra-life Monitor can be seen at the top of the loop in the Green Hill Zone stage.
 * Item Monitors make several appearances in LEGO Dimensions. Extra-Life and Ring monitors appear in several places, and Item Monitors displaying a picture of a 1x1 Lego brick serve as the Minikit collectable in Sonic's level pack.
