The Sonic Boom[1] is a move that appears in Sonic Adventure and Sonic Adventure DX: Director's Cut. It is a technique used by Chaos 4, where it attacks with energy waves.


When using the Sonic Boom, Chaos 4 shoots out a red blade-like shockwave at its opponents from its tail.[1]

In gameplay, this technique is used during the Chaos 4 boss battle. When preparing to use this attack, Chaos 4 will let out a red flash, and will then shoot out either one or two Sonic Booms. If the player is hit by this attack, they will take damage. Chaos 4 only uses this attack when the player is far away from it.
