I thought of something interesting. Obito, Madara and somehow Izuna finds themselves in the EQGirls universe.

I also noticed that they remind of the Dazzlings in some way.

Madara is the leader and the fabulous one with long and crazy hair. Similar to Adagio in some ways. (She sings. He dances. XD)

Obito is the mean and violent one. Usually grumpy and would actually kill you if you annoy him. Aria isn't like that, but she is the grumpy one.

Izuna(don't know his canon personality so I'll use the picture for ref) He is the kind and soft spoken one. In ways, kind of like Sonata(only he isn't ditsy)

Sets before the battle of the bands.
