A Hulk-like creature does not necessarily mean that the Hulk by himself can destroy Superman. Let's see now, can the Hulk fly into space? Can he live through a nuclear explosion? Can he survive the heat of the sun? I recall my brother who is a comic enthusiast that even Stan Lee said in an interview that DC had more powerful heroes BUT he said that @ least Marvel's strongest was not an alien from another planet. I'm sorry if this bursts your bubble, hon, but as I see it, I really don't think Hulk can beat Superman up if there is no Kryptonite or anything that drains his power.
Of course I could be very wrong in this & this is only my opinion, one I built on info from my brother & from what I know of the both of these super heroes. I am confused, though, hon: IF Domsday is from Krypton then why doesn't he have Superman's powers? Supergirl does and she is from that planet in the red star system. Even the dog, Krypto had super powers sine he was from there. So I guess Wikipedia is not the standing expert on this & perhaps we should contact someone in DC. Just a thought.
Hon, I luv the drawing & the way you have this since I am a Marvel girl, I admit I can be wrong about this & I shall do research on this soon. In college you never use one source of reference in case the one you use is not accurate. I'm not saying Wikipedia is not right but I saw the first sign that something is not right if Doomsday is from the same planet that Superman, Supergirl & even Superdog is but he doesn't have the same powers. Something doesn't add up BUT that could be the school teacher in me, hon. Sorry
