Ult. Air Trap (ULT.エリアルセット,ULT. Eriarusetto?, lit. "ULT. Aerial Set") is a move used by Emerl in Sonic Battle. In the game, it serves as Emerl's ultimate Air Trap.
Whilst in the air, the user deploys two mines which land on the ground, set to detonate if they come into contact with an opponent. The mines can also be detonated if the user deploys another set of mines.
