@0ps Not really, it just explain the superpowers, though the MC's power source might be different since his immortality is beyond even the 'unkillable dude' project from Terror Man and he was tooted as their best effort toward immortality (though the same guys also made a brain that control a space station with a giant laser so maybe the 'unkillable guy' was their best effort after losing the MC's, just like they lost the Terror Man MC's power.)
The only other context that you need from Terror Man is that the guy you see learning of the Season 1 Bad Guy's death is the MC of Terror Man so the Bad Guy's revenge might have been related to the Terror Man plot.
