Cyclops. Anyone who describes him as a "boy-scout" or a "cop" is so off base.
That’s literally what they call him in the X-men animated series: a Boy Scout.
I think it was right before he jumped without a parachute and survived by nuking the ground so hard the updraft saved him from the fall.
Isn’t that by Wolverine? That don’t really count
I think Rogue also calls him that. Maybe not though.
