What is everyone's Powers?

Most of the most recognizable characters have a singular aspect, a single quantifiable power concept. Sonic is super speed, Knuckles is Super Strength, Tails is Super Intelligence, Amy believe it or not has Lightning Based Abilities, using her hammer to channel it into strength. But after that, I'm lost, I see an alligator, a hedgehog from the future, a cat, then theres the Robots that Gain Sentience out of nowhere?
