The Grandmaster, who´s aware of the existence of the DCU, challenges Batmite to a game to determine who would fare better against an Alien Queen, if heroes from his universe, or from Batmite´s. Batmite accepts and, the two joining forces, take 2 Alien Queens, as well as 8 champions from the MU and bring them to the DCU (this takes place before Flashpoint) where, in an isolated, secluded area, they create an arena for them to fight. The 8 people from the MU are Captain America, the Black Panther, Daredevil, Moon Knight, Shang-Chi, Night Hawk, Taskmaster & Bengal (this is before the Black Panther gained superhuman abilities or Shang-Chi enhances by Tony Stark).
The 8 people from the DCU are Batman, Nightwing, Robin (Damian Wayne), Red Hood, Wildcat, Catman, the Bronze Tiger & Richard Dragon.
The goal is to see which team would defeat an Alien Queen with less losses or, should there be a tie on that regard, in less time. Or if indeed, any of the 2 teams can achieve that result.
The members of both teams only have the standard equipment that they usually carry on themselves. No prep time, no bloodlust (except in the case of the Alien Queens...), morals on, all participants in character. The fight takes place during the day, so neither Moon Knight nor Night Hawk have superhuman strength.
First team DC engages one Alien Queen, then team Marvel engages the other one.
