Trial Of The Metahumans

1,Captain America
2.Deadpool
3.Deathstroke
4.Wolverine

Out of these characters who can last the longest without the following.

1.Food
2.Water
3.Oxygen

Tie between Wolverine and Deadpool.

12 minutes and all four are dead without power.
At meta level I think the 8 minutes extra would give them time to burn the oxygen and convert it into steam like a vape.
