What if all the strong ninjas were in Konoha Obito attacked?

[Somnath Ghosh]

minato is only can mach up with obitos teleportation

 

[icewarya]

uchiha's were somehow involed in the kyubi attack so they planned to stay inside.... for all others kyubi is too much to handle....

A few people couldv'e gave Tobi a hard time or beat him. Orochimaru along with Jiraiya and Tsunade all together.
Itachi could most likely kill him, Hiruzen as well

 

[namikaze12]

Only Minato was able to fight Tobi at that moment....not even Prime Hiruzen could do a sh!t...
And Kyuubi was more than enough for the remaining even though in the end, it was Minato who dealt with the monster...
