Bomb (obstacle)


 * This article is about the obstacle. For other uses of the term, see Bomb (disambiguation).

Bombs (爆弾), also called Mines or Obstacles (障害物), are hazardous obstacles, which are seen in numerous games in the Sonic the Hedgehog series. Touching these obstacles with a playable character will cause them to explode instantly and inflicting damage on the player, resulting in the loss of a shield, Rings or a life if not protected, and/or slow the player's movements down.

The bombs are first seen in the original Sonic the Hedgehog and have made numerous appearances in almost every game in the series since then. While the appearance of these obstacles has been different in almost each game, their purpose is similar to the spikes and spiked balls, which is to inflict environmental damage to the reckless player. While having similarities comparing to spiked balls, they do share small differences.

Description
The bombs are usually found in the games' playable levels where serve the purpose of complicating the player's progress. They are located in numerous places where they can either be blocking the player's path or be hidden from the player's view until they can hit him/her. They can be set on numerous pathways of the different zones or even Special Stages, where they have been place in specific formations that makes it more difficult for the player to pass through without touching them. Many bosses and different enemies from several games are seen using bombs as their weapons too.

The bombs' appearance and size have varied between the different games. In some games, bombs and spiked balls are closely similar in appearance to each other and share numerous features; both obstacles are known to be spiky, black or dark grey colored, and floating in groups. In most cases however, bombs are small or medium-sized, where spiked balls can be large and spinning in one place. In recent games, both obstacles have been separated more clearly.

Sonic the Hedgehog (1991)
THe bombs made their first appearance in the original 16-bit version of Sonic the Hedgehog,where they had a completely identical look to the spiked balls on the seesaws in Star Light Zone. During the boss battle in this zone,  Doctor Robotnik will drop bombs on seesaws from his Eggmobile that has small pipe attachment. These bombs will start flashing for several seconds after being dropped down, before exploding and releasing small red projectiles that will fly everywhere, similar to badnik with same name. The player can use these bombs to either send them flying back into the Eggmoblie by using seesaws, or to send Sonic up into the air to reach the Eggmobile by using to shift the seesaw.

In the 8-bit version of the game with same name, Robotnik is seen dropping exploding balls during the encounter at Jungle Zone Act 3. These balls keep moving around the vine until it explodes, which leads to Robotnik dropping another one to take its place. In 8-bit variation of Scrap Brain Zone, Ball Hog badniks are also dropping exploding balls to the player's face.

Sonic the Hedgehog 2
In Sonic the Hedgehog 2, bombs are featured most of the time in Special Stages, where the player has to avoid them. In these stages, the bombs are black spheres with white spikes around them and red center lines and orb on the middle of it. Touching one will cause them to explode, which will make the player lose 10 Rings and cause Sonic/Tails to fishtail for a second. Bombs in these stages are usually arranged in strings, but they can also be arranged as large Rings in midair, which the player has to jump through without touching them.

In the boss encounter at Casino Night Zone Act 2, Robotnik will drop small spiky bombs from his Eggmobile if the player run past him below, which will then explode and release two small projectiles. During the boss battle with the Death Egg Robot, if the player goes behind the large robot, it will launch small Robotnik-looking robot bombs, which will explode after standing for while.

Sonic the Hedgehog CD
In Sonic the Hedgehog CD, bombs can be encountered during some of the boss battle segments of the game, through their appearance differs between each boss battle.

Robotnik's pinball attachment at Collision Chaos can drop flashing blue bombs from the bottom hatch. These bombs does not damage the player when they make contact and explode, though they can change Sonic's flying course then trying to reach the boss in the pinball arena. Also, on Robotnik's conveyor belt trap in Quartz Quadrant, the doctor starts dropping black spiked bombs down on the player, which, after crashing to the ground, will separate into four smaller spiked balls that can damage the player upon contact.

Sonic the Hedgehog 3 & Knuckles
In Sonic the Hedgehog 3 and it's continuation Sonic & Knuckles, bombs are more less featured. The large battleship at the end of Angel Island Zone Act 2 will drop flat bomb missiles from ship's bottom tubes down on the player, which the player can avoid by keeping on running straight forward.

In the boss encounter for Sonic and Tails in Lava Reef Zone Act 2, Hot Mobile can shoot magma-resistant mines into the air, which will then drop down nearby. These spiked mines however, will move with the lava flow towards the Hot Mobile, while the player has to avoid them by jumping from one platform to another. In order to defeat the Hot Mobile, the player to allow eight mines to crash into the Hot Mobile.

Egg Robo is seen dropping two different kinds of bombs that is only seen in Sonic & Knuckles alone during Knuckles's storyline: one at the beginning cutscene and near the end of the Launch Base Zone. Both of these bombs are seen to have Eggman's face on it.

Sonic 3D Blast
In Sonic 3D Blast, there are numerous purple colored mines, with yellow and black stripe around them, set in few of the zones in the game, and can block some of pathways. If the player gets too close to them, they will explode and release small projectiles in their wave that will fly around the area.

Mines can also be found in the Special Stages of the game, though their appearance and effects differs between the versions of the game. In the Sega Genesis version, the mines have slight different coloring for each Special Stage. While they do not blow up when the player touches them, they will cause the player to lose 10 Rings each time. If the player has no Rings in his/hers possession when he/she makes contact with a mine, the player will lose in the Special Stage. In Sega Saturn version, they are similar to the bombs from the Special Stages in Sonic the Hedgehog 2, resembling the bombs from that game instead of mines, and will explode if the player touches them, causing the player to lose 10 Rings in each time.

Sonic Pocket Adventure
In Sonic the Hedgehog Pocket Adventure, bombs repeat their role in the Special Stages. In this game, they are identical in appearance to the bombs seen in Sonic the Hedgehog 2, and are as well arranged in the same string and ring formations. When the player touches these bombs, he/she will lose 10 Rings.

Sonic Advance Series
In all three Sonic Advance games, bombs are featured as obstacles that ae used by different enemies.

In Sonic Advance, the bombs are also seen in the game's Special Stages, where their appearance is that of floating, light grey explosives with red lines. They functions much like they did in Sonic the Hedgehog 2, as the player will lose 10 Rings after touching it once. Likewise, they are similarly arranged in strings and huge rings, but they can also be arranged in small packs, which the player only can have a small possibility to get through.

In Sonic Advance 2, the Egg Bomber Tank can shoot round bombs with Eggman Empire logo on it. The Aero Egg can also drop missile-like bombs to stop the player from reaching Eggman. Eggman can also drop napalm bombs during the Egg Frog boss battle, which will sweep the surface after exploding. These bombs are impossible to avoid by simply jumping, unless the player changes the gravity in right time.

In Sonic Advance 3, during the final conformation against Eggman on his Hyper EggRobo, the large mecha can fire four red bombs which it can keep inside the arena. They do not explode if the player lands on the top of them, but touching them from sides and below will make them explode. By standing on top of them, the player can ride with them to the cockpit of the mecha and hit Eggman. After a while though, the bombs will explode.

Sonic Heroes
Bombs later made a reappearance in Sonic Heroes, where they are once again featured once in the Special Stages in the game, and can be found in both the Bonus Challenge and the Emerald Challenge. In this game, they are black, floating orbs with yellow and red spikes around them. They are usually arranged in large string rows, often creating a wide fields of bombs. Some of the bombs also spin around the tube of the Special Stage as well.

In this game, touching the bombs will cause them to explode and set off a chain reaction that will set off other bombs nearby, though they will not damage the player. Instead, they will decrease the player's speed considerably and the playable character will fishtail for few seconds after the bombs have exploded. This can be a great hindrance to the player, as high-speed movements are essential to these Special Stages.

Sonic Rush series
In Sonic Rush and Sonic Rush Adventure, bombs are variable obstacles that can be seen in few stages.In the underwater sections of Water Palace, water mines can be seen hanging on the bottom from a rope. The player can then grab onto the rope at the bottom of these water mines, which will then start pulling the player towards the surface. However after grabbing it, the player has three seconds to let it go before the mine explodes and damages the player.

In Sonic Rush Adventure, numerous enemies are carrying bombs as weapons. In the Special Stages and general sea routes, there are also a huge amount of water mines lying on water, which can damage the sea vessel that the player is currently riding upon contact. These mines, however, can be destroyed by attacking them with the vessel's means of offense.

Sonic Unleashed
Bombs are featured as one of obstacles in Sonic Unleashed. In this game, they appear as black-colored, spiky spheres with red round center and lines. If the player touch these bombs, he/she will take damage and Sonic will lose balance while running.

The game also features timer bombs, which are similar to regular bombs, but are cubic in shape. After touching these bombs once, they will start to beep and flash for few seconds, before they explode and inflict damage to player, if nearby. If other cubic timer bombs are caught within the blast redius of another detonated cubic timer bomb, they will automatically detonate as well.
