There’s actually another young, female, telepathic superhero originating from DC Comics whom I also think would be a good fit for Millicent Simmonds.
With a dark backstory and threateningly powerful psychokinetic abilities, this Titan requires a threateningly powerful performer like Millicent Simmonds.
Opening it up to more characters who can express themselves non-verbally, like telepaths, felt like an appropriate and fun direction to go.
However, unlike Dolphin or Saturn Girl, this character is not deaf nor unable to speak orally, but I thought that it would be unfair to tie down the actress’ options to those two categories.
