Man everyone is giving these really thoughtful suggestions and I just want to see the Cobalt's take down one of the big chonkers like Asterion or Themba shadow of the colossus style. Those three are absolute menaces and I love them.
Also everyone seems to think that in a fight of Kota v Luke then Kota would win, which isn't necessarily wrong, but this is Luke, he is both A a horny bastard, and B scrappy as hell. He would love that XD
