Ningame

is Might Guy's personal summon. He watches over Rock Lee when Guy isn't around.

Appearance
He is a very large tortoise. His shell is red with a yellow underside and swirls on the top with markings around his eyes which are yellow. He also wears a Konoha forehead protector around his neck and an orange bandage on his right front leg. He is also capable of speech just like most summoned animals are.

Chūnin Exam Arc
He was summoned when Lee challenged Sasuke Uchiha prior to the Chūnin Exams, and prevented the former from opening the Eight Gates. Guy appeared on top of the tortoise shortly after.

Confining the Jinchūriki Arc
Guy summons him while chasing after Kisame Hoshigaki while losing momentum after being thrown by Killer Bee. He complains that this is the first time he has summoned him in years, and the fact he did so in mid air. Guy uses his shell as a platform and jumps again causing him to fall to the ground, he ricochets off a giant tortoise's shell before hitting the ground.

Trivia

 * It could be considered ironic that Guy's summon is a tortoise. Tortoises are normally regarded as slow while Guy's entire fighting style focuses around speed and agility.
 * Ningame is one of ten summons that wears a headband, suggesting that his loyalty is strictly to Konoha. The other nine are Hiruzen Sarutobi's summon Enma and Kakashi's eight ninken.
 * He has seemingly grown larger during his absence.
