Metal Slug's resident Gigachad, Allen O'Neil

Notes:

The reason I post him there is because his physical appearance matches near-perfectly the Gigachad archetype, including the fact that he uses literal scrap pieces of tank as a handheld weapon.
The picture itself comes from the gacha game, Metal Slug Attack.
Allen O'Neil, Metal Slug and all that is related to Metal Slug belongs to SNK Corporation.
