Gotham: 10 Best Batman Villains Not Yet Used On The Show
4. Lady Shiva (Sandra Wu-San)
As one of the few characters in the DC Universe capable of going physically toe-to-toe with Batman, Lady Shiva is an important character in the world of The Dark Knight. In the comics Shiva often functions as a trainer to many members of the Batman family.
Most notably, this is seen in the aftermath of the main Knightfall story arc, where Batman is nearly killed by Bane and then must be retrained by Shiva before reclaiming the mantle of Batman.
In a hypothetical Gotham appearance, Shiva could occupy a similar role, helping to accelerate a young Bruce Wayne's journey towards his destiny.
