Adapting in Marvel

Brian transmigrated into the Marvel universe and became a newly awakened Mutant, obtaining the ability to "See through and understand the laws of operation of everything."

At the time of Mutant's first battle, in order to make himself stronger, Brian turned into a brain-opening maniac without hesitation, observed Mutant's brain, mastered its ability, and combined thousands of variant abilities in one.

At the moment of the final battle between X-Men and Hellfire Club, Brian ascended the throne and became the new king of Hellfire Club.

Then he faced Apocalypse and plundered Apocalypse's variant ability.

He also used Kitty Pryde's ability and upgraded it to travel through various Marvel timelines, harvest Mutant Ability, and finally grew into the immortal Mutant God.

And all this started when Brian just awakened his ability and met a black taxi driver named Darwin.

By plundering Darwin's reactive evolution at the beginning, Brian had the foundation to gain a foothold in the Mutant universe, and also made him a level 5 Mutant on par with Black King Shaw.
