Critical Hit
The Scrapper is a fierce melee combatant. In hand to hand, no other hero can compare. All Scrapper melee attacks do extra damage. This is mainly useful when facing named opponents.
Scrappers do +2 damage with melee attacks.
Build
A scrapper uses Powers skill and Super schticks or Martial Arts skill and Fu schticks.
If going with Powers the obvious power choices are Abysmal Spines and Magic Melee. With Fu, anything goes, but Signature Weapon and Dragon Fist from the Path of the Selective Master are both common, though not in combination.
