Just out of curiosity how long would it take for Hulk to surpass these characters physically if he starts from base? No amps for the characters. Be reasonable.

Abomination

Kurse

Solomon Grundy

Namor (full hydration)

Hercules

Thanos

Tyrant (depowered)

All-Star Superman

Pre-Crisis Darkseid

Destroyer Armour (full Asgard control)

Trion Juggernaut

Galactus (full power)

68 minutes

I have not been reading hulk for a year now... is there a steady increase rate for his strenght that I don't know about?

The only ones I see him surpassing at all are Abomination, Namor, Hercules (Kurse & Destroyer maybe as well?). Don't agree with the idea that his strength is limitless because I don't think his anger is. The WWH storyline pretty much showed him at the angriest he could ever be (in the sense that what on earth else could possibly make him angrier).

He'd surpass Abomination and Namor pretty quickly (isn't he stronger than Namor at base anyway?). Hercules would take a while, long enough that Hercules would have a good chance of putting him down before he matched him.

Hulk can overwhelmed all of them except of Destroyer, Trion Juggy and Galactus full-fed...
