Fire Sonic is one of Sonic’s Alternate Forms, first introduced in Episode 8. Using a Fire Flower will be able to make him transform, like Mario.

Sonic’s personality is still the same in this form, just like in his regular form. He is still laid back, but in his form he is a bit more confident in his abilities to deal massive damage to his foes and help his friends.

Fire Sonic has all of his primary abilities, even when transforming. His strength is greatly increased, being almost as powerful as Mecha Sonic (although this is unconfirmed) and possibly Shadow. He gains the ability to easily move almost as fast as teleporting to catch up to enemies for multiple punching and kicking combos. His speed is greatly enhanced, being able to accelerate at higher speeds than what he could orginally do. His body becomes enveloped in flames when he does speed up, making him able to ram and knock out anything in his way. His Hurricane Kick ability is powered up, even allowing him to finish off with a stronger kick. Fire Sonic can shoot out fireballs, like Mario, at even greater speeds and more power, taking out a lot more enemies much faster. When he focuses his energy and flip-kicks, a flame shoots out, more powerful than regular fireballs. He can also use a powerful move that starts off with him running around his enemies, creating a ring of fire, stopping after it’s created, and finishing it off with a cyclone of flames, making that possibly his most powerful attack in his transformation.
