Gamabunta and all the other summons.
Blood and any remains left over would still allow the immortals to regenerate.
Ino body possessing and then "eating".
1. Ino needs to have support from her teammates to setup her body possession as misuse of it would leave her physical body helpless while it is incapacitated. She only has one shot if she's taking down an entire group.
