Healing Factor (Deathstroke, X-23, Wolverine or Deadpool)

Sorry if this has been done....of these 4 who has best healing factor. If you want to add any others feel free. I chose these 4 because heal factor is one of their major assets in battle.

Scans are welcome!

Wolverine or Deadpool

I think Deadpools is the best. He can grow back limbs quicker than the rest (as far as I know, I could be wrong)

@rev_sulphur: In the "Deadpool Kills Marvel Universe" His head get popped by the Invisible Woman and grows back....quickly. But that was a ridiculous story haha.

Deadpool by far.

Deadpool I think.

This.

Deathstroke has no place here,btw

A better addition that fits the OP's guidelines would be Hulk

Wolverine i think.

Wade

deadpool>wolverine>x-23>deathstroke

Deadpool

Supposedly X-23 has a better healing factor but Logan's feats are better.

I'm pretty sure when they engineered Deadpool's healing factor from Wolverine, the modified it so it was more powerful/faster-acting/stain-resistant/machine washable/etc.

Deadpool.
