Just curious

Regeneration let's you heal from damage, while invincibility prevents the damage from happening, therefore invincibility is considered op.

Super speed and strength are fine though, most characters have at least some form of increased strength or speed

No i mean like without bais toward our characters
Like if a normal human had it

???

Whar

If you were told to you could have one but you cannot be impossible to beat which would you choose

Ohh

Regeneration, because if it's like what Deadpool has then cancer and most diseases or viruses wouldn't be a problem
