Feral form mecha!
I requested for it to be done in a kind of manga style. So the Japanese text reads: "Henshin! (transform)" in the top left panel and 'Gao!', a roaring sound effect.
Another fun note is that the armor/mecha was based off Transformers G1 Sky Lynx, still one of my favorite Transformers to this day.
