[Mass Effect + The Hulk] The Hulk ends up in Tuchanka in a pre-genophage era unleashing... well, its Hulkness. Fast-evolving-and-reproducing krogan see him as a worthy challenge and try to take him on for months/decades. Centuries later the Salarians discover the krogan. How are they different?

You have the scenario... GO!

My personal take is of some kind of bigger even more resilient krogan who have abandoned gunpowder and nuclear weapons and returned to more physical ways and brutish aggression.

(If not the best subreddit for this, let me know which one would be. If it is, let's have fun).

EDIT.- In this scenario the Hulk has no means of leaving Tuchanka. Some of the krogan he fights are effectively killed, but there are also some that survive and manage to flee. The specifics reasons for the fighting is to be determined by each poster. Even if you consider one of the iterations in which Banner has more control over the Hulk and the transformation: 1.-Please consider of Tuchanka's constant danger. 2.-Please, no super scientist Hulk. Leave the scientist side to Banner or come up with awesome stories xD.

Every year, young Krogans gather near where the hermit has made his refuge for another right of passage in a world where only the strongest survive.

But unlike other rituals, they are not here to hunt or attempt to kill the beast - this is an altogether different rite of passage, for today it is not the strong or even the most cunning who will pass it.

The males are excited, they've heard the stories of the most dangerous creature on Tuchanka - elders claim to have seen it been eaten by thresher maws only to tear it's way out of their guts. Murals depict the day it arrived, and the months where it rampaged across the world, further leveling the ruined cities in it's rage before it finally retreated into the remote mountain rage where it now resides.

No Krogan has been able to best it, let alone kill it, those that try have wound up dead or maimed. Some clans even go so far as to worship it as a god.

The path through the mountains is a challenge in itself. When they arrive at it's lair, he ones closest to the front may see it's natural state and wonder if they have found the right beast. But once it's provoked the small pink animal will metamorphosis into the green, hulking monster... then they will run.

Only the most sure and fleet of foot will make it down the mountain unscathed.
