Hands up who remembers ROM: The Space Knight? The character has been tied up with rights-holders Hasbro for years to my knowledge but it looks like that’s been sorted now. He’s coming back via IDW for Free Comic Book Day this year:
“Rom the Space Knight #0 will feature an introductory 10-page story of Rom’s arrival on Earth, an incident that sets up an ongoing Rom series launching in July 2016.”  Great cover by Zach Howard and Nelson Daniel
