Dark Horse Killeroid Runs The Gauntlet
Killeroid from the Ultraman Tiga comic was one of the most impressive villains I have seen in a long time. The scary part is that he never even actually tried as he and Tiga stated. His live action version was just as powerful in some ways, and in some ways not. And since TV Killeroid is, well, TV related, I'll use this amazingly powerful Dark Horse version. I will list as many feats as I can that he had. But remember, they stated and showed that he wasn't even trying to fight.
Slept in the earth's core, then walked around in it
Flew through the earth's atmoshepere
Hovered in deep space with no issue
Created earthquakes that went for miles in one punch
Stood and took earth shattering lasers while having a conversation
Made Ultraman Tiga his ***** with a few moves
Destroyed Makeela, a cosmic shape-shifting monster who destroyed civilizations with no effort, in one wave of a hand
Absorbed a nuclear holocaust that was wiping out every single thing on earth without any effort at all, and even said "Oh, please! THIS is what is destroying all life on the planet?"
Punched through five feet of steel without trying
Crunched a diamond into rubble with his bare hand
Punched his way through thousands of feet of ground in less than a minute
Chucked a building into deep space with one hand
Knocked out a 500 foot tall monster with a few punches when he changed to six feet
Teleports away faster than a Luminizer(super light blasts of destruction)
He had the skill of a million super soldier warriors.
Remember, all of this time, he wasn't even trying
