Seagate

Seagate Prison is a facility in Marvel comic books that has also been introduced in the Marvel Cinematic Universe. Up to now, it has only been seen in the One-Shot All Hail the King, where it was shown to be the place that both Justin Hammer (Sam Rockwell) and Trevor Slattery (Ben Kingsley) had been sent, following their crimes in Iron Man 2 and Iron Man 3 respectively.

It is due to reappear on both the big and small screens in Ant-Man (as the place where Scott Lang, played by Paul Rudd, was held) and in Luke Cage (where the titular character, played by Mike Colter, will be held).

In the comic books, it is known for holding a number of villains and notable characters, including Beetle, Comanche, Crimebuster and Plantman and a television series set in the facility could be extremely interesting, as a number of recognisable characters from the source material come and go (with possible cameos from the likes of Ben Kingsley along the way).
