Hulk is definitely more of a Grundy ripoff, then Doomsday is a Hulk ripoff. Doomsday is an entirely different type of character, tbh.
But aside from those already mentioned:
-Deadpool/Deathstroke
-Deadshot/Bullseye
-Black-Cat/Catwoman
-Doctor Fate/Doctor Strange
-Green Arrow/Hawkeye
-Brainiac/Ultron
-Dick Grayson/Bucky Barnes
-Original Doom Patrol/Original X-Men
-Fantastic 4/Challengers of the Unknown
-Nova Corps/GLC
-Red Tornado/Vision
etc. etc.

Grundy had and has adapting powers btw. and to my knowledge Grundy was an inspiration to Hulk.If anything Doomsday shares more similarities with Grundy than Hulk. No alter ego, if he dies he comes back with adapted powers, design, color, super strength, invulnerability etc.
1962 First appearance, cover.
Solom Grundy first appeared 1944
Here a cover 2 years prior to the first appearance of Hulk.
Justice League of America (1960 1st Series)Nothing bad being inspired by Grundy imo, Hulk has traits of Dr. Jekyll and Mr. Hyde too, so the twist is there.

...and throwing in that Grundy actually took on more Hulk qualities over the years, as DC writers were inspired by the Marvel character.
I mean it is no shame if Hulk isn't an original character, but stop saying there is nothing different about Doomsday and Hulk.
Hell just the way their powers operate, Doomsday doesn't get stronger the angrier he gets, that is Hulk. He gets stronger by adapting and evolving to attacks that kill him. Sometimes he adapts to attacks on the fly. Hulk isn't known to suddenly gain a ranged attack if his opponent has one. He's also not thousands of years old. He's also not an alien.
