This is my first time doing one of these so here it goes....
Sasori and Deidara
or
Kakuzu and Hidan
Oh shit they're fused?
Team Immortals easily has a chance then....well actually who's body is it Sasori's or Deidaras?
Not really XD
Give him Sasori's puppet body + point blank C4 (since he wont be affected) = victory!
How would he be able to make it so large from the ground?
If its point blank it doesen't need to be large. It would be like when Deidara did against Sasuke on top of the bird. Instead this time Deidara can keep the pressure on him instead of running away thanks to said immunity.
