if they fight which team you gonna choose and say why ?

Team A. Madoka is there. The fact that someone like Godoka is on a team means they would win easily.

Definitly Team A

bcz they have powerful people like
Itachi
Lelouch
Luffy
Erza

Itachi alone will be enough to defeat others..with his susano no one can stop him.......he he he h

Team A,Of course!
'Cause there are all strong characters!!
Including Erza!!

It was a tough choice since all four teams have 4-5 members I know of with their strengths and abilities. But I would probably go with either Team A or Team C since both teams have strong fighters and some has great strategies to use, especially since Team A has Erza, Luffy, Itachi, Lelouch and Eucliwood on the team while Team C has Rias, Roy, Rin, Suiginotu and Black Star on their team.

Team A
They have Lelouch and all Lelouch has to do is use his Geass and he'll kill anyone by controlling them to kill each other .

Team A has Madoka, who's.. a god, the brains of Lelouch, and the battle skills of Levi.

Team A seems pretty OP so I'll stick with them.

Team A is pretty OP so yeah XD

But still, there's team B with Touma, Gintoki and Izayoi, 3 characters that defies all logic so I'm pretty much rooting for them too XD

Team A,everybody said enough so i won't say anything since you already know the reason

Team A of course! there are all strong characters on there.

Team A. Everyone else already said why.

Team A. They've got such strong characters. Luffy, Erza, Itachi, Levi... and then a mastermind like Lelouch and a psycho like Yuno. That team is marvelous, lol.

Dunno the other two, but they must be good.

team a
cause there is Eucliwood Hellscythe,erza, itachi,and lufy
Eucliwood Hellscythe's words can defeat them

Team A. It has the strongest characters.
