The Shield is a recurring powerup in the Sonic Boom video games. A defensive power-up, it envelopes the playable character in a spherical barrier which protects the wearer from taking damage once.
The Shield are sphere-shaped bubbles that has the ability to negate damage taken from enemies and different kinds of damage-inflicting level hazards once. After receiving a damaging blow, the Shield disappears and the player usually flies slightly backwards without taking damage, meaning the player will not lose Rings or be defeated if they are hit without Rings. Shields will not protect the player from falling into bottomless pits or getting crushed however.
The Shield can in most cases be obtained by breaking/touching item boxes displaying the Shield's icon in their respective games. Once obtained, the Shield will surround the playable character until it is broken or the level is completed.
Sonic Boom: Rise of Lyric
In Sonic Boom: Rise of Lyric, the Shield does not appear as an individual power-up. Instead, it is created via the "Bubble Shield" Power Glyph which spawns one Shield whenever the player's Ring count hits zero.
Sonic Boom: Shattered Crystal
In Sonic Boom: Shattered Crystal, the Shields are translucent with a yellow tint. They are found within the adventure levels where they can be obtained by opening spherical silver and red item capsules with a blue bubble inside them. These capsules break when touched and can be targeted with the Homing Attack.
By unlocking complete sets of Blueprints, the player can obtain upgrades for the Shield. The "Shield Award" upgrade lets the player automatically obtain a Shield upon reaching the first Checkpoint, and the "Map Accelerator 3.0" upgrade will highlight Shield locations on the Adventure Map.
Sonic Dash 2: Sonic Boom
In Sonic Dash 2: Sonic Boom, the Shields are transparent green bubbles. In gameplay, they can be found on the racing courses inside glass capsules with a red cap on the top and bottom and a green kite shield on the inside.
When obtaining the Shield, it not only prevents the player from taking damage, but also from losing a try whenever they come to a stop from colliding with an obstacle. After a certain period of time, the Shield will disappear. However, certain Sprites allow the player to manipulate it; Aegis extents the Shield's duration and Targa makes the Shield appear more often.
Sonic Boom: Fire & Ice
In Sonic Boom: Fire & Ice, the Shields look like they did in Sonic Boom: Shattered Crystal. Like in Sonic Boom: Shattered Crystal, they are found inside the adventure levels where they can be obtained by opening item capsules resembling golden bubbles with a group of seven circles inside them. These capsules break when touched and can be targeted with the Homing Attack.
