Full intel means Hiruzen becomes prey to a strong Bansho Tenin + Asura Path missile combo/strong Bansho Tenin + chakra rod to the skull/strong Bansho Tenin + Soul Rip at the start of the match, giving Hiruzen no time to bite his thumb and summon Enma, use Kage Bunshin shuriken, or do anything besides die, really. And that's just one of the many ways Pain could win. Hiruzen's elemental jutsu and shuriken are useless against Preta Path and Shinra Tensei, whereas Hiruzen himself doesn't have the durability to shrug off Deva Path's more powerful Shinra Tenseis. Some Paths can solo this match, such as Deva, Animal, and Asura.
