Yeah ,remember when Oro touched KN4 and he vaporises in a sec,he had no choice but to switch bodies,the Kyubi chakra burns everytning that comes in contact with.Naruto's clothes are the same like Goku's,witch he had from King Kai
I don't think it was specified that the chakra was actually hot, I thought it was just the nature of the chakra itself that sorta leaked through his open wounds and kinda took over. In which case, why wasn't there any blood on his clothes?
Reminds me of the VoTE and when Naruto was b*yatchslapping Sasuke with Kyuubi chakra and I was wondering why he wasn't getting burns. We all saw what happened with Sakura when she got a little Kyuubi slapping. Subtle inconsistencies are common in the Naruto universe.
Why not, if it makes sense in the plot? (I know, don't ask for logic in a manga :\)
I thought it was cool how in Guyver the Bioboosted Armor, when Sho transformed to Guyver-mode his clothes got destroyed and then when he transformed back to human form he was naked (at least the first few times).
