the most powerful alien is alien x. there is no doubt in that. but as ben's second most powerful alien ,I can state clockwork. he can simply destroy omnitrix aliens except intangible aliens and diamondhead by slowing the time,and then just simply turn them into ashes with his time ray. there were many situation in ultimate alien or omniverse which clockwork were able to solve them with ease. for example, diagon.ben could use clock work time travel powers to prevent the seal from breaking. there were many other situations which he was able to solve them with his time rays or time travel powers.
