I’ve been reading some of the old Marvel comics lately (got a big book of them for Christmas, just finished issue 12). Is it too much of a stretch to imagine that Crimson Jack got his ship from the Battle of Scarif in Rogue One?
Well it does fit Jack’s description of how he got it, so why not. It’s a pity it’s no longer canon because Jack hijacking a star destroyer at Scarif could have made a pretty interesting story.
(Btw, which omnibus is is that you’re reading? Hopefully it’s not one of those that stop right in the middle of a plot-line. The Doomworld story-line is fun, but in my opinion it only gets better from then on. All of the Goodwin/Infantino stories released prior to ESB are pretty great.)
