Looking for a NOVA aka Richard Riker for dcmu so Quill can banter with him and have hilarious shenanigans since they're both "grounded." Jensen Ackles would be an amazing PB but open to any!
And obviously a Gamora, Rocket, Drax, Angela, and Groot would be fantastical. Also Captain Universe, Tony Stark/Iron Man, Major Victory, Yondu, Victoria.
