Mecha Allen is the independent variant of the original Allen O'Neil in Metal Slug Attack. The Mecha Allen's description is much more different than the ones in Metal Slug Defense. Mecha Allen is stronger than the original Allen, but is weaker than Wrath Allen. It gains an increased boost in its stats, but loses the stun capability that original Allen had.
