I am going to call Hive/Alveus Alveus.
When referencing Deadpool/Wolverine, I am actually referencing Mutants with regenerative abilities.
I will use the term Consume to refer to Alveus's power to consume a human to regenerate himself.
I will use the term Possess to refer to Alveus using a dead human body to host himself.
End of Foreword
What would happen if Alveus attempted to consume Deadpool/Wolverine?
I assume that Alveus can posses and consume Deadpool/Wolverine. They are not Inhumans which is the only condition that has to be met for consumption and possession. I assume that possession might be more complicated as they need to be dead; not only are they hard to kill, they will also put up a fight :). Furthermore, since Alveus can regenerate as well, the use of Deadpool/Wolverine seems a bit redundant. Perhaps the mechanics of Deadpool/Wolverine's regeneration is better than Alveus's ability.
For Alveus to consume a body, it appears that there are only two conditions that must be met:
- The consumed must be human
- The consumed must be alive
I am not sure what the mechanics of Alveus's consumption ability is. I believe that Alveus controls parasites that eat the flesh of the human. The parasites return the nutrients or themselves to Alveus.
I imagine that if Alveus were to attempt to consume Deadpool/Wolverine, that the parasites would consume while Deadpool/Wolverine would regenerate. (similar to Wolverine vs Phoenix in X-Men Last Stand).
I also imagine their is no canon answer to this question.
