The Kusanagi couldn't pierce him, but Shizune's tiny needle can?
What can Asuma do here? Hiruzen's doton: doryuheki > all of Asuma's ( and Anko's ) katons.
The team lacks the speed feats to dodge Enma's attacks, and none of them can damage Enma's body.
Again, Anko can immobilize the monkey with her snake jutsu. It happened so it can happen now, too. I was talking about Asuma vs Enma. : D Asuma clearly kills the monkey.
If Enma is in his fleshy form he will be pierced by a needle.
Enma is mostly useful here as a staff.
I actually believe the three jonin are faster than Hiruzen. But speed isn't really everything. Asuma could probably go almost toe to toe with Hiruzen, while Shizune hinders him with her poisons and Anko with her snakes, and summons her big filler snake. : D
I seriously see the jonin winning extremely high diff.
