Clark is a unit that appears in Metal Slug Attack. Parts can be obtained through the P.O.W. Rescue minigame. Clark attacks with the Iron Lizard as his primary weapon. When using his special attack, Clark throws one barrel of explosives in a small arc towards the enemy. The barrels fly high enough to hit enemies on the ceiling, and with File:MSA Skill small +.png 3 unlocked, his special recharges faster. With File:MSA Skill small +.png 4 unlocked, Clark throws three barrels at a time instead.
