9. Firelord

11. Thanos
12. Galactus

How far does he make it?

Please explain how he wins each match & what alien forms he uses to do so.

Urm... isnt everyone 2 onwards a planetary threat?

Ben would stop at 2 then, unless he manages to get Alien X to work. In which case he stops at 3.

Don't see him getting far without re using some aliens or being able to switch between them. Isn't making it past 2.
