This sort of thing might be more clear once we (kickstarters) get the next chapter installment.
I am trying to gauge the relative power levels of minions. What are some real world examples or Marvel/DC examples of d10 and d12 level minions?
I think street thugs are d4 minions. Veteran street thugs or regular army soldiers would be d6.
I would categorize the Sentinels (X-men villain robots) as d12 Minions. Giant threats that it's possible to take out in one hit, but you gotta get lucky, they're a threat the whole time they are around, and good luck if you get hit by one at full power.
In My Hero Accadamia there is a villan attack at the disaster training center, some of the low grade, expendable bad guys could be 10s
probably most of the card game targets with higher HP too. Voss might send a lot of D6 but some could be 10 or 12. And when an Orginization Underboss calls in "the big guns" to "take care" of a problem they would still be minions. Also most of the big scary cryptids would still only be minions
