Fan Casting Grayven in Adam Strange

Tries to conquer Ranagar City and take control of the Zeta beam technology to further the Apokoliptan conquest. Or because Grail told him to as it could bypass the being locked out of Earth thing. Honestly never knew about this one but Michael Rooker could do a Yondu type, but maybe even more morally questionable? Don't really want a vying for Darkseids attention as he'd be gone by this time anyway (set after JL 3) More of a sees a weakness in Darkseid
