I think of Knuckles as being a geokinetic/earthbender that can simulate pyrokinesis/firebending through the heat of magma/lava. Sonic Battle said that Knuckles has "supernatural control of the earth", so it's possible he can channel energy from the earth's core to use fire-based attacks.

Or something like that.
