When a character like venom from spider-man foes fast forces says he automatically breaks away do you still roll for breakaway???????

SYMBIOTE: Venom can use Shape Change and Plasticity and automatically breaks away.
this is what his card says

Venom wouldn't have to roll for breakaway unless an adjacent opposing character can use plasticity or if there was some other game effect that makes a character not automatically break away.

I believe it was the old Galactus and some other old colossal figures which said something like "Breakaway rolls automatically succeed."

With wording like that you would roll break away, but not with wording as quoted above.

Thanks guys me and my buddy where wondering because of the rule "that a one always fails and a 6 always succeeds and could not find anything on line that said either way.

I can see how your logic led you here. Although Harpua and other posters are correct, I had never considered this logic before. It's nice to see no matter how well you know the rules, there is always someone with a different interpretation leading down another path. I applaud your rules logic even if it ended somewhere other than intended.
