  1. Okay… um..
    Utimate Heatblast, Ghostfreak, and Alien X were never canon. Fanfiction probably shouldn’t apply in the list…

  2. Bruh wtf, ultimate big chill, humongousaur, swampfire and pretty much every other ultimate besides way big COULDNT beat ultimate Kevin but echo echo was about to murder him with a single sonic doom. Wtf lmao, how is he ranked below fucking big chill and swamp fire. The others weren’t even fucking canon like heatblast ghost freak and alien X, the only one they got right was the abomination that is ultimate wild mutt, they didn’t even add fucking cannonbolt. It goes like this: (weakest to strongest)
    Big chill
    Echo echo (humoungaur did nothing to ultimate Kevin meanwhile echo echo was about to murder him)
    Way big

  3. So,i’m not sure about this, but in my opinion clockwork’s a pretty strong alien too.
    Clockwork can fire green time rays from his hands or chest, which have various effects like sending people back in time,aging an object/person to dust,restoring individuals who have been erased from time, sending them into a different timeline,and reverting them to a previous state while also immobilizing them.
    eventhough If something hits Clockwork’s head key, he can be badly stunned; this shows that Clockwork is not very agile, as he admits that he “is not good for dodging,with enough power and skill, Clockwork can perform a temporal consciousness conversion in which a person’s consciousness is swapped with that of a younger or older version of the target in question,much like what Eon did to Ben Prime’s 16 and 11-year-old selves.
    Hope this helps,i have used some references
