The Teen Titans from the CN show (Robin, Starfire, Raven, Cyborg, and Beast Boy). All feats apply. No summons for Oro. Orochimaru has his arms. (1) bloodlusted. (2) Not bloodlusted.
@ImTheDamnBatman: Raven`s telekinetic powers are going to be a big problem for Orochimaru as he has no real counter to said ability but he definitely does have the speed as well as versatility advantage. A Raven with no morals would instantly transform into her demon form and have him harshly BFR`d or she could use her Soul-self powers to take control of him.
Teen Titans win here.
The main blow would be from Raven. Orochimaru has never done well against "magic"/illusions AKA mind tricks -- Proof was shown when he went up against Uchiha Itachi. He could possibly deal with Cyborg, Robin, Beast Boy and MAYBE Starfire but definitely stops at Raven. Since this is a team battle and there is no prep involved, Orochimaru can't just focus all his attacks on Raven. Therefore, Raven might take down Oro before he even realizes it.
Allowing Orochimaru to do summons would turn the tide of the battle in his favor though. Edo tensei is beastly and I'm pretty sure, freaking illegal even in the Anime/Mangaverse. Summons can't go down even if the summoner does. Well, shit.
