Wrath is of absolutely no threat to Jack.
Maybe not alone, but with Gorgon I think he poses a formidable threat.
I don't remember enough of Samurai Jack but I think Gorgon vs Jack is a close fight. Wrath might give the team an edge.
I'd say Gorgon has what it takes to give Jack trouble and steal a few wins, but Jack takes a healthy majority in a one-on-one fight against Tomi.
