GH (presumably somehow connected to "Guest House") is the code designation for a partial blue-skinned alien corpse that was introduced in "T.A.H.I.T.I.". The corpse is floating in liquid in a hollow cylindrical tube, and is missing legs and a pelvis, with tubes going into its organs. These appear to export substances that are synthesized into:

Of these, GH.325 was revealed to have been used on Coulson for his resurrection and was acquired by Coulson and his team to heal Skye.

All connected elements and resources were seemingly buried with the collapse of the Guest House.

GH's bodily appearance is similar to Ronan the Accuser, a Kree in Guardians of the Galaxy.




  • Skye's actress Chloe Bennet claimed that the blue alien corpse was from a Kree[1]. She, however, stated that this was not official confirmation, since she was just guessing like most fans[2].
  • Lady Sif tells Coulson that she has met many blue-skinned aliens. She mentions Interdites, Levians, Pheragots, Kree, Sarks, Centaurians, and Frost Giants.[3]
