This article is about the boss. For the item, see Gemini (Item).

Gemini is one of the bosses that can appear in The Basement. Gemini is composed of not one, but two separate "bosses": One large twin with a smaller twin attached. They both have the same amount of health, sharing the health bar fifty-fifty.

The large twin is called Contusion and the small twin is called Suture.

Behavior

• Contusion will chase the player, then periodically charge at them at high speeds. Afterwards it will stop to catch its breath, presumably because it is being choked by the umbilical cord holding them together.
• Suture, while attached to the larger, will shoot tears at the player if not behind an obstacle.
• When Contusion is killed, Suture will detach and begin charging furiously at the player. Caution is advised when trying to juggle it, as the knock-back from tears could cause it to gain speed.

Trivia

• Gemini appeared in the original Binding of Isaac.
• Blighted Ovum is the posthumous version of them, and Steven is the alternate version.
• Gemini are named after the astrological sign of the same name; not to mention that the symbol of Gemini are twins.
• Gemini were originally designed to be a boss in Gish and were called Suture Contusion. The larger one being Contusion for the boot shaped dent in his head.[1]
• Contusion is the medical name for a bruise, whereas suture is the medical name for a thread used to close gaping wounds, commonly called stitches.
• Suture seems to be more dependent of Contusion than the latter one is from him, as Contusion will ignore his brother's death and won't change his behavior while Suture will seem to start panicking if Contusion is killed before him.

Bugs

Bug! For The Cellar to unlock, the player must kill all the Basement bosses once. Gemini, however, counts as two depending on which part is killed first.

Bug! If you Stun Suture at the same time that it tries to shoot Isaac, it will cause the sound effect to loop infinitely until Suture is killed.

Bug! If Gemini's chain hits Red Poop or Spikes, the chain will disappear but Contusion and Suture will still be joined.
