There are currently 37 Marvel Future Fight Heroes and Villains that can be played. There seems to be a good chance that they will release more in the near future with an update. When starting out for the first time you’ll get Captain America, Iron Man and Black Widow. You’ll then get another hero very soon in the story who will be random.
Marvel Future Fight Heroes have a max level of 50, but their rank will have to be increased to raise the starting max of level 25. There are 6 ranks and each one will increase the level max by 5. Biometrics will also need to be found in order to recruit and upgrade rank.
As rank increases you will be able to unlock various skills and passive buffs that can be used during battles. Every one has 4 different pieces of gear that they wear which can also be improved. Materials will be needed to make gear stringer and will be found on Normal missions.
There are 4 different types to fight with including Combat, Blast, Speed and Universal. Every one has certain other characters that they go well with. They will trigger a Team Bonus that adds passive buffs, special skills for battle and do a team attack when switching to them in a fight. Having a group that work well together can drastically increase both survivability and DPS.
