Topic: Where did Bossk go?
Canonically, the last time we saw him was Empire Strikes Back. After that, however, we never really get to KNOW what he does afterward in the new canon.
Also yes I know Bossk made a small cameo in Return of the Jedi but he was in there for like 2 scenes in the background. If Disney is really gonna say Bossk died during the Carkoon Battle then that'll be more than disappointing for such a visually intriguing character.
At least Bossk is gonna appear in that new "Bounty Hunters" comic which is coming in March. But I'm 99.99% sure that takes place before Return of the Jedi.
