Aqua Shield

The Aqua Shield (アクアバリア, Akua Baria^?, lit. "Water Barrier"), also known as Aqua (アクア, Akua^?), Bubble Shield or Water Shield, is one of the shield type power-ups that appear in the Sonic the Hedgehog series. It can be obtained by breaking Item Boxes with a water droplet symbol on them, which will then surround the playable character with a visible, but bouncy sphere-shaped shield, similar to a water bubble.

With an Aqua Shield, the playable character can take damage once without losing Rings or a life, and can move in underwater sections of the Zones without drowning. Also, when used by Sonic the Hedgehog in most cases, it allows the player to perform the Bound Jump. In certain games though, the Aqua Shield can have different functions or have additional abilities.

The Aqua Shield was first introduced in Sonic the Hedgehog 3. While the Aqua Shield has not become as recurring power-up like the Lightning Shield, it has made some noteworthy appearances through the series.

Game appearances

Sonic the Hedgehog 3 and Sonic & Knuckles

The Water Shield made its first appearance in Sonic the Hedgehog 3 and its add-on continuation Sonic & Knuckles, alongside the Flame Shield and Lightning Shield, where it can be obtained by breaking monitors with water droplet symbols. The player can also collect Water Shields from Bonus Stages by getting blue gumballs with B-letter on them.

Like other shield type power-ups, when a playable character is equipped with a Water Shield, it will protect the player from one hit worth of damage from enemy attacks and/or contact, spikes, and other environmental hazards in the Zones by keeping the player from losing Rings or a life. After blocking a damaging blow however, the Aqua Shield will disappear, and the player is usually send flying slightly backwards. However, the Aqua Shield is not able to protect the player from falling into bottomless pits, being squeezed by Crushers, or the time limit of completing the stage running out, all of which give an instant death.

While equipped with a Water Shield, the player's playable character cannot drown from staying in underwater sections of the Zones for extended periods of time, meaning that the player can remain underwater for an unlimited amount of time without having to utilize any Air Bubbles to extend his/her time underwater. Also, when Sonic is using the Water Shield, it allows him to use the Bound Jump.

Besides blocking damage and allowing the player to breath underwater, the Water Shield can also deflect regular projectile shots from Badniks, such as the Blastoids from Hydrocity Zone.

Sonic R

The Aqua Shield (called simply as Aqua in Japanese version) made another appearance in Sonic R, where it has drastically different functionalities.

Like other items in the game, the Aqua Shield can be picked up by the player from floating Item Panels with blue orbs on them during the race. After obtaining it, the playable characters get surrounded by blue shield, and the player is able to walk across the water surface on race tracks, whereas without the Aqua Shield, the player will sink into the water and move slower. After coming back to bare land, the player will then lose Aqua Shield instantly.

Sonic Generations

In the console/PC version of Sonic Generations, the Aqua Shield is both an equipable Skill for Classic Sonic that grants one Aqua Shield once each Act, and an Item Box power-up. In this game, the Aqua Shield retains the effects it had in Sonic the Hedgehog 3 and Sonic & Knuckles.

The item boxes with the Aqua Shield appear exclusively in the Challenge Acts "Aqua Shield Challenge" and "With Your Powers Combined" where the player has to use it to clear the Acts. The Skill for the Aqua Shield can be bought from the Skill Shop for 300 Shop Points after clearing the "Aqua Shield Challenge" and costs 70 Skill Points to be equipped. To activate the Skill in gameplay, the player has to press /.

Sonic the Hedgehog (1991)

The Aqua Shield appears in the 2013 re-release of the original Sonic the Hedgehog. To obtain it, the player must access the Level Select and in the "Items" category, they must switch to either "S1+S3" or "S2+S3". Some of the original Shield Monitors will then be replaced by the Aqua Shield. It also appears as one of the objects that can be placed freely in Debug Mode. Its functionality remains identical to that in Sonic the Hedgehog 3 & Knuckles.

Sonic Lost World

The Aqua Shield made another appearance in Sonic Lost World, where it can be found in Item Boxes with blue bubble symbols on them. In this game, it is referred to as the Aqua Shield.^[1] Along with other power-ups and items, the Aqua Shield is also an power-up that can be obtained from the Miiverse, where players can share power-ups and items with one another via Miiverse.^[2]

This does not grant the Bounce Jump capability its original incarnation did, (due to this a part of Sonic's regular moveset), but it does, as in its original incarnation, protect Sonic from drowning. In the Nintendo 3DS version, the Aqua Shield is a regular Item Box power-up in Tropical Coast. In addition, the player can also make Aqua Shields in Tails' Lab using twelve Blue Materials and twelve White Materials. Once made, these handmade Aqua Shields will be stored away for the player to use later in the Zones. During these Zones, the player can look up the Item Bag and select the Aqua Shield to instantly bestow it onto the playable character.

Sonic the Hedgehog 2

The Aqua Shield appears in the 2013 re-release of Sonic the Hedgehog 2 where its purpose is near-identical to that in the 2013 re-release of the original Sonic the Hedgehog. To enable the Aqua Shield in gameplay, the player must first open the Game Config menu in the Level Select. In the Items category, the player must either highlight the second (the icon displaying the Shield with the three elemental shields) or fourth option (icon displaying Random with the three elemental shields) before starting a stage.

Sonic Mania

The Aqua Shield reappeared in Sonic Mania and its expansion Sonic Mania Plus. Like its original appearance in Sonic the Hedgehog 3 it prevents the player from drowning as long as it it is equipped. It also gives Sonic the ability to use the Bound Jump. The Aqua Shield is also able to protect Sonic, Tails and Knuckles from the blue chemical liquid present in Chemical Plant Zone Act 2. It also behaves differently when bouncing on slopes; rather than always bouncing straight up, it will bounce perpendicularly to the slope.

Trivia

• Although the Water Shield appears in Sonic & Knuckles, there are no underwater sections in any of the zones presented in the game.
• If the player is playing as Knuckles in Sonic & Knuckles, monitors with Aqua Shield have red water droplet marks instead of blue. This is due to Sonic and Knuckles sharing different color palettes in the game.
