my killing team would be...

Gaara: first striker, and defensive shield.

Kabuto: Strategic force, medic jutsus..

Naruto: seconed strike, uses the cover of gaara's sand to suprise and deal out Kage bunshins...

this team is strong even without pulling out any big cannons, and when they do use thier hidden powers... people will die...

the only team that can rival this one would have to be the 3 sennins or the Itachi + gang...

this is, without a doubt, the most powerfull genin team..


BTW: too bad i couldn't put Hinata in... but the 3 men teams are only for practise, there can be 5 men teams or any other number..
