Too Many Cool Powers
The more everyone watched, the more they liked this X-Men realm. And as they watched, they also learned that senior Wolverine's real name was Logan. But they liked the name Wolverine better.
It was too cool and made him look like a God.
When senior Wolverine flew out of his flying carriage (car), he quickly healed under a minute. They could feel the strong healing qi technique from him
'What a useful skill,' they thought.
They also realized that senior Wolverine had a super-sensitive nose. He could smell anything from a mile away. No smell could get past him. This could be useful for alchemy.
In Alchemy, one needed to distinguish the components of a pill or an elixir by the smell. Even distinguishing poison in a pill could also help save a life.
The Alchemists watching had already determined what powers they wanted.
