The Balor is a Rebel vehicle introduced in Metal Slug Advance.


The Balor is a Rebel Army submarine vessel used as a stationary weapon to assist ground troops. The Balor presents itself by being lowered on a crane. It attacks by dropping torpedoes in arc, and a Rebel soldier is on board with an RPG-2.

The Balor is only present in Mission 2 of Metal Slug Advance.

In Other Games

Metal Slug Defense

The Balor appears as a floating stationary unit. It deploys itself on the nearest ground unit. Its normal attack is the Rebel using his RPG while its special is dropping a barrage of torpedoes on the players.

Metal Slug Attack

The Balor returns in the "Tough & Cool" Extra Ops as a Rare Boss unit. Pieces are now available in the Ptolemaic Another Story 5.

The Balor now deploys much closer to the nearest enemy unit. This is advantageous when no enemies are present, since it'll deploy right on the base. The Rebel fires homing missiles while the sub's special now increases the number of torpedoes dropped. When its HP is depleted, the Balor will drop its last set of missiles before it explodes.


  • In Irish mythology, Balor was the tyrant warrior of the Fomorians, He is often described as a giant with a large eye that wreaks destruction when opened.
  • In Metal Slug Defense, the Balor was incorrectly placed in the Independent faction before being fixed in the subsequent update.
