Simone Missick has been everything Marvel cans could have hoped for as Misty Knight in Marvel’s Luke Cage. She just hasn’t had every visual element of her character, most notably Knight’s bionic arm. She simply hasn’t needed one, until now.
As fans saw in The Defenders, Knight lost her right arm, setting up an enhanced replacement. Knight will be appearing with her bionic arm in the second season of Luke Cage, as shown in the image above from Entertainment Weekly.
The arm was likely supplied or at least funded by Danny Rand (Finn Jones). It should give her abilities beyond those of her former, natural limb. It will be interesting to see how her potential new status as an enhanced individual will impact her relationship with Luke (Mike Colter) and any other Defenders who may appear.
