Invisible Woman is coming to MARVEL Strike Force along with the rest of the Fantastic Four team. That being said, you will need to unlock her as a playable character. You won't get the entire team together, but they do work best as a team, meaning you'll want to unlock them all. To unlock Invisible Woman you will need a a 5-star villain team. Specifically the Sinister Six. This is because Invisible Woman herself is a 5-star heroine.
According to the MARVEL Strike Force team you won't have a chance at getting Invisible Woman unless you have a full 5-star team of Sinister Six villains. While you can already grab Green Goblin from Nexus 5-6, the other villains are heading in soon. They will be available starting sometime next week. For Shocker, you'll simply need to complete his campaign node. Vulture and Mysterio will be appearing in the Arena and Raid stores respectively.
If you've already got a Sinister Six team set up, then you should be able to head right into the game and acquire Invisible Woman. In addition to telling players how to acquire her, the development team has also given more details about here abilities.
First and foremost she plays more of a supportive role. While she has attacks of her own, she is best suited for helping to protect her teammates. To do this she uses abilities like her special to clear out debuffs. For instance, her special ability will allow her to clear two negative effects from herself and all of her allies. She can also use the special t apply a steal buff to herself and all her allies, which can help to reduce incoming damage.
This ability has a few more useful advantages too. It can clear stealth from all allies, or just the one with the most health. If you choose the latter then the ability will replace stealth with three deflect and immunity for two turns. Her special is also capable of increasing her and her team's defense for up to two turns.
Her ultimate ability is where things get more powerful. With this move, Invisible Woman decreases the offense for all enemies for two turns. The move will also apply a power barrier to all allies. This barrier has HP that's equal to 40-percent of Invisible Woman's maximum health. That makes for a precedent to get her health as high as possible so the barrier is stronger.
In addition to her Special and Ultimate abilities Invisible Woman also has a basic attack and a passive. The passive attributes are always active as they work in the background. This is where barrier comes in quite handy. A passive effect of it is that enemies who attack any ally with barrier up will receive 250-percent incoming damage. That makes it an offensive and defensive move that could be invaluable in harder fights.
She has other passive abilities as well. When paired with Fantastic Four allies and Namor, all of them gain a 20-percent buff to their max health. They really are stronger when paired together. As for her basic attack, Invisible Woman will first do 290-percent damage to the primary target. Directly after attacking she'll cast a barrier on herself that will be equal to 10-percent of her max health.
When you get right down to it Invisible Woman is a powerful heroine you'll want in your roster. Especially if you're going for the entire Fantastic Four team.
