The Black Widow is a playable character in Marvel Future Fight with the Speed type. You will start the game with Black Widow for free. In my opinion she is fairly weak with her low HP and low defense. If your planning on using her make sure to find the Best Team so you can take advantage of passive buffs and new skills.

Skills – These are Manual action or passive abilities that apply during battles. You start with 2 and will need to reach Rank 3 for the 3rd skill, rank 5 for 4th passive and rank 6 for 5th skill. It can take a very long time to get all of them so try and focus on a good group for the long haul.
