Snake Eyes in the DC Universe would be interesting to think about. Imagine him and the Joes fighting against the League of Assassins. Batman teaming up with Snake Eyes would be cool to see.
Most universe's version of Snake Eyes are, well, relying on honor there is not going to help much. He's a ninja...and will use dirty tricks and worse to win, there are exceptions to that with limits to what he's willing to do, but trying to rely on honor on a black ops ninja... And even with honor involved, imagine trying that with one like in Resolute, that's just going to leave a dead Batman behind.
I was wondering why Bats said Snake Eyes had a no kill rule. He killed all the time in the original comics and the movies; and in Resolute. But I guess it makes sense for one of the Saturday morning show versions to have this rule.
Bruce recently fought Snake Eyes to a stalemate multiple times during the Batman x Fortnite. So it should be possible for him to beat Snake Eyes, with High Difficulty.
They have met. Fortnite crossover but it counts. They were evenly matched. Learned to respect each other since neither could talk in the Fortnite dimension.
Batman holds honorable fighting. However, he learned from Wong fei important lesson: went out match…cheat. Also snake eyes would prove as a good ally, as well as Batman could help each other out with Any ninja threat. Also, Batman‘s next contingency plan should be about Charlie from firestarter or Carrie the psychic power teen.
While Snake Eyes is honorable, he also cheats like crazy in many fights. In GI Joe 21, he faces off against a ninja who pulls out a pair of sai's. Snake tosses a GRENADE at him!
