Burst Attacks are a mechanic in Burst Champions.
A Burst Attack is a mechanic similar to "super attacks" in other fighting games. They act as very powerful attacks for whichever character they're assigned to. A Burst Attack can be pulled off when a character's Burst Meter is filled up all the way (except for Lime, who can unleash her Burst Attack as long as the Burst Meter is filled to at least 25%).
