i think it would b hard to beat em but i can think of a couple teams that would at least give em a run, if not beat em!!!!:
1st n 2nd hokage's
Madara n his brother
"The Sage's" Naruto n Jiraiya
"The Uzumaki's" Naruto n Nagato
Jiraiya n Orochimaru
i also wanted to say dat i think that people on here really discount how much power Gaara still has. He's still Kage n leader of da alliance forces for a reason...
