Not neccasarily there are several versions of sonic that all have there own pros and cons a few are
-Dark Sonic
-Supersonic
-Werehog Sonic
there are many others but I do not think that one is more powerful than the others.
well it depends. sonic is the most powerful if he gets the chaos spere.
Sonic, although Mario doesn't like people to know that.
hes the most badest transformation in the world
Flamethrower Fire blast stomp secret power hyper beam ------------ Yep, its fire blast. Hyper beam is not that good.
most people think he did but he might return one day...:)
I think you mean the fourth transformation. It's Believix and it's the most powerful transformation (so far).
They can all be quite stubborn, Sonic never gives up, Knuckles is hot headed, Shadow refuses to be seen as weak, Eggman continues his evil plots, Amy won't stop chasing Sonic. In short, quite a hard question.
As Eternal Sailor Moon (Her final and most powerful transformation) her last and most powerful attack is "Silver Moon Crystal Power Kiss!" :)
Shadow the Hedgehog's most powerful form is often considered to be his Super Shadow form. In this transformation, he harnesses the power of the Chaos Emeralds, granting him enhanced abilities such as increased speed, strength, and the ability to fly. Super Shadow also gains access to powerful attacks, including the Chaos Control technique, allowing him to manipulate time and space. This form significantly amplifies his already formidable skills, making him one of the strongest characters in the Sonic franchise.
Stoats and weasels are one of the most hyper creatures.
um doctor robotnik? i know he was the main enemy, dont remember if he was the most powerful or not
In terms of physical strength, Knuckles the Echidna is the strongest Sonic character.Sonic and Shadow are tied in terms of speed.And Shadow is the strongest in terms of harnessing the power of the Chaos Emeralds.
