characters that should be playable

PeanutSwag

in the game, there are many characters that we should be able to play as. There is jessica jones, i believe she should be playable because in the MCOC promo art, she appears on them often. She also has her own character model.
2 more characters that should be playable are Emma Frost and Mr. Sinister. In the loading screen for the monthly event with sabretooth,bishop, and sentinel, there are pictures on the wall that show names and portraits of the characters. E. Frost is showed as a name but the picture was covered. N. Essex had a picture but most of it was cut off, same as the name, it showed "N. ESS"
the last character that should be playable is heimdall. This was just minor, but his name is mentioned on the cosmic awareness mastery, confirming that there is a possible chance of him entering the contest.

There is a character wishlist megathread somewhere. That’s where the mods push threads like this. They release one champion every other week, for balance reasons they can’t just put out 5 or 6 Mutants in a row. Also, they have stated that they have no plans to release Jessica Jones as a playable character.

Jessica jones is lame though would just be black widow 2.0.
