Red Skull

The Red Skull gained possession of the Tesseract – the first Infinity Stone to appear in the Marvel Cinematic Universe – back in 2011’s Captain America: The First Avenger, but trying to touch it with his bare hands resulted in him apparently being killed.

Since then, however, it has been rumoured that it merely transported him across the universe – it is the MCU version of the Space Gem, after all – and, therefore, he may well still be alive and kicking in the cosmos.

Unless he’s undergone a personality transplant while in space, he will still be seeking out power. With that in mind, he could have obtained one of the remaining Infinity Stones. Could he be an accomplice of Thanos in the Avengers: Infinity War movies? We think there’s a good chance of that happening!

Now for the most obvious potential holder of one of the remaining Infinity Stones.
