Theraclese

Wow..this is a match, Doomsday probably throttles Swampy a few times before realizing the futility of his efforts, Doomsday does have the clear edge in strength, speed and endurance but Swamp Thing is still an elemental who has taken the likes of supes and captain atom, and i believe can either sedate or constrain Dooms through Chlorokinesis without killing him as to avoid him becoming immune after death.

Though we haven't directly seen too many feats from Dabura, (only been in a couple fights) I can say pretty confidently that he is between perfect cell and his super perfect form in terms of power, and still a force to be reckoned with, seeing everything that Cell was capable of. Not to say he has all of Cell's techniques but Dabura isn't without his own set of deadly abilities; he has been seen to be extremely fast-with thought speed to match, countless ways of manipulating ki, molten breath, razor slashes, and of course spit that turns you to stone. King Raizen at his fullest we've never seen, but everyone in all realms seems to have revered him as the strongest and possibly still the strongest even in his starving form. What we know is that he is an elite S level demon which implies that he is able to destroy something the size of a large city with relative ease, though even beings like Nappa in DBZ could do that and he's infinitely below Dabura, I'd say Dabura is a planet-buster, Raizen has shown a few energy manipulation tricks, and probably has strong shields too, but it just seems like Dabura has him beat in every way, all he rly has to do speed blitz and spit on him and it's all over
