10 Supporting MCU Characters That Must Appear In The Disney Plus Series

Technically Wonder Man has never appeared in the MCU, but with Nathan Fillion already cast as the character for background material in Guardians 2, it would be criminal for him not to appear at some point.

For the benefit of those that don't know, James Gunn had cast Fillion as Wonder Man for Guardians of the Galaxy Volume 2 in a cameo role, yet the scenes in which he were visible were cut out, which was rather disappointing.

So, seeing as Guardians 3 is such a long ways off, bringing Fillion in to appear in one or some of the Disney+ shows would be a smart move. His presence in this universe is far more cosmic based thanks to Gunn, meaning the character could appear in Loki. He could even join the already surprisingly large cast of Wanda Vision, given his comic book history with the Scarlet Witch.
