Sonic doesn’t only love his friends, he also cares for the animals that share his world. So when the nefarious Robotnik imprisons them the plucky hedgehog quite rightly vows revenge. Every time you face off against the rotund Doc, you not only have the satisfaction of trouncing him and watching him flounce off in a sulk, but you also experience the joy of seeing all Sonic’s freed woodland friends bounce and fly away to safety. Awwwww.
