This is cute, he really can't. Iron Sand World or whatever it's called simply restricts his movements, now Orochimaru on the other hand due to Soft Physique, can easily maneuver around the thorns and strike accordingly.
L0l stop not a chance. Gamabunta easily jumps out his Iron sand rage as soon as the match starts not happening.
Iron Sand spikes on the ground, so wherever Bunta lands, he's pierced and poisoned? Orochimaru can easily make his sword go into levitation mode and sneak up on the d-low.
Sasori iron sand isn't like Gaara sand it's very limited one jump gets him out of the aoe weather it's in the air or on the ground.
