Infinity War reveals that the Red Skull was teleported to Vormir, where the Soul Stone is kept. The former villain explains to Thanos and Gamora that he’s been doomed to a purgatory where he can guid those who seek the Soul Stone but never attain it himself. Once Thanos claims the stone, Red Skull disappears.

In Infinity War, we find Red Skull on the planet Vormir, acting as the guardian of the Soul Stone, which he cannot possess himself. (So close, yet so far.) He informs Thanos that to obtain it, he must sacrifice something he loves, and he will all know what happens after that.

The Red Skull, also known as Johann Schmidt, is a HYDRA member and former Nazi whose face was deformed when he took an early version of the super-soldier serum that would eventually turn Steve Rogers (Chris Evans) into Captain America.

The hooded figure is Red Skull (originally played by Hugo Weaving but recast with Ross Marquand for Infinity War), the villain of Captain America: The First Avenger. In The First Avenger, Red Skull obtains the Tesseract (the Space Stone) and uses it to make weapons for Hydra, an offshoot of the Third Reich.
