In-Game Description
"A commander-in-chief in mercenary troops. He offers his services to the Regular Army."

Heidern is a playable unit in Metal Slug Attack, first appearing in the Extra Ops "Operation Ikari".

While Heidern has good combat capabilities, his high AP cost and moderate health (with no skill to boost them) greatly hampers his performance. He can be considered an inferior variant of Aswang, who is similar to him but has much more health and a lower AP cost.

His special, Storm Bringer, is fairly unique. Heidern performs a somersault and generates an aura around him. Enemies near Heidern will take rapid damage, and Heidern will heal himself with the damage inflicted on his foes. While it forces him to be in melee range (and can possibly kill him), Heidern can recover most if not all of his health if multiple enemies are being hit (and stunned at the same time). Storm Bringer can be interrupted by stuns.

Like Leona, as soon as MSA Skill small + 3 skill is unlocked, he is able to counter any close range attacks or any attacks that would knock him back.

When placed on a deck with the Donkey Slug, they form the "Operation Ikari" team, lowering their AP costs by 10%.

Attacks

Close Range

Attribute grenade Moon Slasher (Spread) - Swings his hand like a blade in an arc, dealing damage to enemies near him.

Long Range

Attribute grenade Cross Cutter (Single) - Swings his hands like a blade, generating a projectile and damaging enemies it hits. Performs twice with MSA Skill small + 2.

Special

Attribute grenade Storm Bringer (Spread) - Performs a somersault towards the enemy and generates an aura around him, damaging enemies while healing himself for the damage he inflicts on them. Duration increased with MSA Skill small + 4.
