It is about Alexander's powers, Ability fusion
He can fuse abilities to create new ones, the commenter idea was fusion of abilities to create Reality Manipulation.
Also, fusing physical abilities to create Eternal Evolution (Like Rimura Tempest or Rou from Re:monster.)
The user has the capability to evolve past any and all obstacles, limitations, restrictions, opponents, and environments, regardless of their current status, enabling them to evolve endlessly and infinitely with no limit or restriction to quantity and quality of their evolution, leaving the users existence in a constant state of evolution and growth.
Unlike most forms of adaptations and evolution, this power is not dependent on external factors and forces, such as environment, opponents, etc. The users will continue to evolve regardless of their internal and external condition and status. Their progress is continuous, even when they have evolved beyond every limitation, opponent, etc.
Otherwise Superior Adaptation( Like The Fury (Marvel Comics),which is the user can adapt to anything and quickly evolve to any situation, automatically gaining the necessary attributes to face them. Users with this form of adaptation that transcends anything can be known as the strongest beings in the world as they adapt and evolve to anything in their respective universe including extraterrestrial threats or even higher beings.
In a fight, they may adapt themselves to resist abilities, replicate and enhance them to surpass their opponents, or spontaneously develop specific countermeasures as they can dynamically analyze and understand anything that is thrown against them to quickly deducing the best course of action for their instant evolution. With said advances users can overpower (nearly) any opponent as they can adapt anything the user desires to support themselves, even if users fail they can learn and adapt to their failures to achieve success.
With superior and adaptive qualities, users can develop defensive and regenerative traits that self-regulates to the user's survival such as instant recovery, advanced immunities and/or even self-reconstruction from anything. With such developed features users can be selectively indestructible as they can counter anything that threatens regardless of what it may be, even if it means achieving immortality under special circumstances.
