Jack and his friends have shown up in Beyond Canon trying to take out the Delta kids but failing. This has been their only appearance so far which made me wonder if their gonna keep being a problem or they're just gonna get killed off by one of the characters. We've already seen that carapacians aren't controlling the commands so it's possible Jack won't get much screen time. The old Jack in the Candy timeline is dead (Maybe Meat Jack is alive? His Midnight Crew self exists there but he just shows up in a backup story) so this might be representative of his importance to Beyond Canon.
