Wolverine and Captain America
Wolverine "without the adamantium skeleton" is practically equal to Captain America .. Both have strength (both can lift 800lbs), endurance, agility, speed, reflexes, durability superhuman and healing factor.. Strengthened immune system and retarded aging (longevity)
Ignoring the adamantium skeleton of Wolverine, and the adamantium shield of Captain, both have almost the same capabilities .. Considering that both are about the same level, both could be considered superhumans or human peak? or maybe mutants?
