Deidara's C4 Garuda? The one that destroys someone on a cellular level. It appears one needs an actual blood stream so Sasori is out, and obito can escape via kumai. But what about the rest? Coukd nagato or konan survive? Could Madara? Could hashirama? Of course not counting godly beings like Kaguya since she'll just regenerate but what are your thoughts? Was Deidara that hax but downplayed? Or was C4 very selective?
