Hulk Killer Humanoid

VS

Second Age Spawn

VS

Doomsday (Hunter Prey)

VS

Uber Pissed Savage Hulk

Doomsday takes out Hulk and HKH pretty handily.

No idea about Spawn.

Second age spawn had no limit to how much he could use his power if I recall...I think he takes it...spawn's energy blasts are Surfer level IMO.
