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 have 140 health each, sharing the health bar fifty-fifty.
The large twin is called Contusion and the small twin is called Suture.[1][2]
Behavior[edit | edit source]
- Contusion will chase the player, then periodically charge at them at high speeds. Afterward, he will stop to catch his breath, presumably because he is being choked by the umbilical cord holding them together.
- Suture, while attached to Contusion, will shoot projectiles 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 him, as the knock-back from tears could cause him to gain speed.
Champion Versions
[edit | edit source]
- Cyan: There is no difference to the normal version, other than dropping a Soul Heart if Contusion is killed last.
- Green: They start separated from each other and have no difference in attacks.

Trivia[edit | edit source]
- Gemini appeared in the original The Binding of Isaac.
- Gemini seems to be an example of a "parasitic twin", with Suture being the underdeveloped twin, dependent on Contusion.
- Blighted Ovum is the posthumous version of them, and Steven is the alternate version.
- The Gemini pair is named after the astrological sign of the same name; not to mention that the symbol of Gemini is a pair of twins.
- The Gemini pair was originally designed to be a boss in Gish and was called Suture Contusion, with the larger twin being Contusion for the boot-shaped dent in his head.[2]
- 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.
- The names of the brothers are inspired by a song by The Mars Volta[1]
