I believe Seitz is supposed to be voicing Grodd, but his being in the cast did leave me wondering whether he also might reprise Etrigan as well.
Yeah, it's great they were able to get Megalyn to reprise Mari. I thought it sounded like her in those clips, but I didn't think they'd be able to get her back as Vixen for this.It's also pretty cool that her voice actress is Megalyn aka the actress who plays her on Arrow and voices her in those animated shorts.
Very happy to be wrong .
