Mecha Knuckles is more aggressive and has more weapons

Mecha knuckles is on his last legs. A gust of wind would evaporate him. (that’s what it looks like anyway, i’m sure he’s very powerful)

Honestly, it feels like a equal fight. Mecha now has increased range with his wreaking ball, while Metal only has close range.

But Mecha seems to have lost his ability to glide, something Metal can do, along with just fly, plus his increased speed.
