Forest Dweller

You fly above him and hold your hand out. The ice block appears, dropping towards him at a high speed. As he is struck, the shards of your mirrors fly into him, piercing hard. He cries out in pain and desperation as he plummets to the ground.
The ice shatters and he flies back up, brimming with wind.

He didn't even announce his new transformation. He's losing his calm.
