A KH comic series (barring the manga) would be nice, but NOT by Archie company. I say this now considering how they handled their series that AREN'T Archie. Case in point, they cut continuation of their Megaman comic and the artists & writers etc had to end the whole thing on something rather lackluster. Now with the Sonic comics, even though that was probably their most popular series, there were practically NO ADVERTISING for it. Instead they placed most of their attention on Archie and flippin' Riverdale. Not only that, but before we knew that the Sonic comic was going to IDW, they were "in talks" with Archie company and all of it lead to so, SO much delay on their Sonic comic; not even letting them actually finish their latest arc jfc (and I doubt there were any refunds to their subscribers for such delays).
imo It's bad business practice for a company to not raise awareness for one of their more successful products. Yes, even SEGA themselves are guilty for this considering that, outside of the Sonic Tumblr, there's little word or any at all about their Sonic Boom TV show (which is rather good imo). And when you look at the ratings of that TV show back in the 1st season collectively, if either SEGA or Cartoon Network had properly advertised the show and it wasn't at such an early timeslot back then, it could have easily reached ratings and viewcounts higher than flippin' Teen Titans Go. And now, even though its timeslot is more manageable, there aren't that many who actually have the Boomerang channel (just ugh, don't get me started on CN and their Teen Titans Go fetish)
Anyways, a KH comic in the story-style of the Sonic and Megaman comics would be interesting. But I would rather support the actual artists and writers of the comic before I let KH anywhere near the Archie company with a 13-mile long pole.
