Bahamut Overdrive (バハムート・オーバードライブ Bahamūto Ōbādoraibu?), also known as Ultimate Super-Being, is one of the final bosses in Contra: Hard Corps. It is a being radiating with energy, result of Colonel Bahamut merging his spirit with the alien cell.


In order to fight Bahamut Overdrive, the player must choose the following options during the course of the game:

  • "Rescue the research center"
  • "Surrender and fight later"

In the last stage, Big Battle, the leader of the rebellion, Colonel Bahamut, succeeds in merging his spirit with the corporeal qualities of the alien, which results in him transforming into an all-powerful symbiotic being.

The creature first manifests as a muscular human-alien hybrid radiating with energy. The brute displays superhuman speed and agility, and is even capable of projecting blasts of its own energy in order to attack from a distance.

However, the entity results to be very unstable and unable to contain its own power, and ends up losing control and transforming into a giant and deformed two-headed monstrosity.

As it grows more unstable, it mutates once again, this time into a beating heart-like organ surrounded by tormented-looking humanoid faces that pulsate outward whenever the heart is hit. It has 120 HP and simply floats around the room until its destruction, which grants 15,000 points to whomever dealt the finishing blow to it.

  • The Somatic Brain Organism miniboss from Contra: Legacy of War strikingly resembles Bahamut Overdrive's third form, being a large sphere composed of humanoid faces that attacks by expanding and retracting, and which also shield a living organ inside it, in this case a brain.
  • In the first phase of the fight, Bahamut's attacks bear some similarities to Street Fighter moves, specifically moves used by Akuma. Coincidentally, Akuma was first introduced in Super Street Fighter II Turbo, a game released just a few months prior to the release of Contra: Hard Corps.
    • The first attack involves a powerful tackle that produces after images. This could possibly resemble Akuma's Ashura Senku, with the main difference being Bahamut's variant is lethal.
    • The second attack involves firing off a volley of energy projectiles while in the air. This may slightly resemble the Zanku Hadoken.
    • The third attack involves firing a powerful energy blast straightforward from his hands. This move bears a similarity to the famous Hadoken from the Street Fighter series, or the Kamehameha from the Dragon Ball series. The former move is also based off the latter.
