3rd raikage tied with the hachibi so taken his powers into account 4th raikage cannot go further than tieing with one of them,
the others,
gaara's defense won't save him for long,
tsunade's punches/kickes wouldn't do that much of a job,
mei has a strong offence but her defence is weak, she'll be done in her first mistake,
since onoki can fly he has a lot of advantage but nanabi can fly as well so it won't matter his dust element wouldn't work on flying opponents and since he's got his hand full with nanabi he won't be able to help the others,
so bijuus tear them apart
