After years of preping Gorilla Grod has convince Animal related villains and a few heroes into thinking they are slaves to everyone and that can never be free unless they fight for it and others epic mind control. Grod told them he was planning something big so he sent a few of his soldiers to get some tech. who were Man-Bat, Beast Boy, Killer Croc and king Shark however they were intercepted by a response team. The first fight begins so who wins.
Namor is far and away the strongest on the field, and definitely the strongest flier (Batman was able to cripple and disable 30 Man Bat ninjas on his own).
They also have sonic weapons (Cyborg) which should help disable a few of the animals. And Cap is almost tailor made to take out a few of them. The main threat IMO is Beast Boy....but again, sonics would hurt him pretty badly.
What if beast boy immediately attacks Cyborg and gets him away from his team. King Shark could deal with Namor, Killer croc and Manbat could distract Cap and Nightwing until their partners got back.
Then...sonics. Which was preboot Cyborg's MO. Beast Boy would be unable to focus, and unable to change shape. Post reboot, all Cyborg would do is BFR them all the Apokolips.
King Shark can't fly, and isn't exactly the brightest tool in the box. Doubtful how he could deal with Namor.
Cap could deal with ManBat and Croc pretty easily, unless we were talking high end Croc who no sold angry Osiris punches. Then Nightwing would taser him into submission.
Could go either way depends on how well the animals can strategize. Theoretically Grodd should be able to neutralize everyone on the other team, at least temporarily, except for Cyborg. If the take him down quickly they have a shot. If not it's Team 2's fight to lose.
