Bump. Also, yes, Achilles is a Greek demigod. But what makes him so associated with Rampage is that he is the only Mythological hero so renowned (at least to my understanding) for dragging his enemy's corpse around via chariot.
I don't know much about this thne, but if he drags dead people on his chariot, why not have his taunt say something like "You dare challenge me?" And smackdown " Now you're going for a ride, eternally"
