I guess. Forces got one (which I heard was actually written by Flynn) so I don't see why Frontiers shouldn't get one too.

Probably just prequel comic(s) or like the TSR one-shot

Whether it should or not, Flynn has stated one will probably not happen, because Sega doesn't want the comics to "steal the spotlight" from the recent games.

Maybe a comic based of it's events in the idw universe similar to Archies game adaptions

Imagine if there was a side quest in Frontiers where you have to give yourself the metal virus temporarily and make your way through a stage without stopping for too long.

Im not sure
