The summoning technique in Naruto requires the user to sign an
ancient scroll in their own blood and end the signature with a
handprint, also in their blood. Multiple characters perform the
Kuchiyose no Jutsu (summoning technique) in the series, each with their
own distinct animal of choice.
Interestingly enough there is an ancient Japanese myth that states:
"The Snake defeats the Frog, the Slug defeats the Snake, the Frog
defeats the Slug." The 3 Senins and their new proteges (Jiraiya is
teaching Naruto, Orochimaru is teaching Sasuke, and Tsunade is teaching
Sakura) can each summon these creatures respectively.
Bees
Standard Bee - The Standard bee used by the Kamizurui
clan. Its stinger is loaded with an exceptionally lethal poison, and it
can be made to carry exploding tags to inflict massive damage on an
enemy. Another common tactic is to have them attack in large numbers,
along with fake bees made from honey, to confuse enemies.
Giant Larva - Similar in appearance to regular bee
larva, only much bigger. Often used in traps by the Kamizurui Clan,
these larvae can drain an enemy's chakra from a distance, making them
hard to attack.
Suzumebachi's Giant Bee - This is a special bee
summoned by Suzumebachi of the Kamizurui Clan. Loaded with a jaw of
razor sharp teeth, a deadly stinger, and wings capable of causing gale
force winds, this insect is a difficult opponent to defeat. It can also
spit massive amounts of honey from its mouth to trap and ensnare its
victims before moving in for the kill.
Birds
Gennou's Giant Bird - This giant bird is summoning of
the Hidden Heat Haze Village ninja Gennou. Since the Heat Haze Village
was destroyed and Gennou is its last surviving ninja, it is unknown
whether or not anyone else has the ability to summon a bird.
Dogs
Dog Pack - This is a pack of about 7 or 8 dogs
summoned by Kakashi during the Zabuza saga and again during the Sasuke
chase. These dogs help Kakashi fight by holding down the enemy to give
him a clear shot. They also help Kakashi track down people. Each dog
wields a cape with Japanese letters that forms a facial expression.
Pakkun - Pakkun is the smallest of the dog pack and
the only one capable of talking. Kakashi summoned him separately from
the dog pack to help Naruto, Sakura and Shikamaru track down Sasuke and
Gaara during the invasion of Konoha. He was the first of the dogs to
track the scent of Sasuke during this chase.
Fish
Piranha Schools - A swarm of tiny, vicious piranha
summoned by the mysterious ninja Ruiga, they appear when he first uses
his Suiton Seibun Houfutsu (Water Cannon Replica) technique to capture
his opponent in a large mass of water drawn from the ground. The
piranha go into the water mass to rip his victim apart. Ruiga can also
move the water masses with the piranha inside to allow the deadly fish
to chase down other prey.
Ruiga's Shark - This is a large, man-eating Great
White Shark summoned by the mysterious ninja Ruiga. He first uses his
Suiton Seibun Seibun Houfutsu (Water Cannon Replica) technique to
create a large mass of water drawn from the ground, then he summons the
shark inside the water mass so he can move the water mass and allow the
hark to chase down its prey. While sharks are usually salt-water
creatures, this one can apparently breath freshwater as well because it
is able to survive in the water mass created from freshwater drawn from
the ground.
Humans
Resurrections - Orochimaru uses a forbidden summoning
technique to resurrect humans. This summoning requires a human
sacrifice for each person resurrected. A spell casted kunai is placed
into the summoned body. This move causes resurrected humans have no
mind of their own; they are completely under the control of the one who
summons them. The only thing left in their minds is the jutsus and
other skills they learned while they were alive. Orochimaru summoned
both the 1st and 2nd Hokage in his fight with the Sarutobi (the 3rd)
and attempted to summon the 4th but Sarutobi stopped his coffin from
opening.
Lizards
Shiromari - Shiromari is a very loyal chameleon summon
with the ability to mold his body into any shape at will. Naruto
encounters him in the shape of a castle which he had been in for fifty
years, acting under the orders of his deceased summoner. He disappeared
after Naruto destroyed his contract scroll.
Monkeys
Enma - Enma is the monkey king and is able to
transform into a large length-altering staff. He was summoned by
Sarutobi during the invasion of Konoha in the epic battle between him
and his former student, Orochimaru.
Pain's Summonings
Pain's Giant Crustacean - Pain summons this creature
during his battle with Jirayai. We only see it for a short time so we
don't know too much about it other than the fact that it has the
ability to make bubbles.
Pain's Giant Chameleon - Pain summons this creature
during his battle with Jirayai. This creature has the ability to blend
in with his surroundings rendering himself naked to the human eye.
Jirayai uses some kind of barrier supposedly made of chakra to find
this creature.
Pain's Giant Dog - Pain summons this creature during
his battle with Jirayai. This creature is a nine headed dog that splits
into nine different dogs whenever it attacks.
Pain's Giant Bird - Pain summons this creature during
his battle with Jirayai. It is not known if this creature has any
special powers as it is only seen for a short time. Like all the other
summons, it shares Pain's Rinnegan eyes and his array of piercing.
Pain's Giant Ram - Pain summons this creature during
his battle with Jirayai. Nothing is known of this creature. Just like
all the other summons it shares Pain's Rinnegan eyes and his array of
piercing.
Pain's Giant Panda - Pain summons this creature during his battle with Jirayai. Pain uses this creature to block one of Jirayai's attacks.
Salamanders
Hanzou's Salamander - This is the personal summon of
the Hanzou and is supposedly made of water. Little is known about this
summon as it is only seen briefly in flashbacks of Jirayia's past, but
it is assumed that it is very powerful.
Slugs
Katsuya - Assumed to be the queen of all slugs,
Katsuya was summoned by Tsunade during the Senin battle. Katsuya has
the ability to split off bits of her own body to form miniature
versions of herself. If she is hit hard enough, she can turn her entire
body into hundreds of miniature versions of herself instantly.
Snakes
3-Headed Snake - This snake, like most of the snakes seen in the series
is gigantic, but is has 3 heads. It was summoned during the attack on Konoha by the multiple sound/sand shinobis.
Manda - Manda is the leader of all snakes and was
summoned by Orochimaru and Kabuto during the senin battle. This seems
to be the only snake-summon able to talk as well as the only one with a
horned head. Manda is extremely bossy and demands that Orochimaru give
him living sacrifices each time he is summoned.
Common Snake - This is Orochimaru's common, unnamed
snake summon. The first common snake was summoned by Orochimaru during
the Chuunin Exams to distract Naruto so there would be no trouble while
Orochimaru gave Sasuke the curse seal.
Snake Hand - This snake summon was used by Anko during the Chuunin exams. A trio of small snakes extends from the users arm and attacks.
Spiders
Kidoumaru's Spider - This large spider was summoned by
the 6-armed Kidoumaru of the Sound Five. It has the ability to summon
its own army of little spiders.
Spirits
Tayuya's Oni- This large blind spirit summoned by
Tuyuya. She plays his flute to tell this blind spirit what to do. This
spirit is composed mostly of Tayuya's chakra.
Toads
Common Frog - This is more or less Jiraiya's helper
frog or possibly his look out frog. It was seen facing the open area
while Jiraiya was peeping at the women in the hot springs. This frog
has no specified name.
Demolisher Frog - This gigantic frog was summoned by
Jiraiya to help defend Konoha during the Sound/Sand invasion and also
made an appearance at the hospital when Jiraiya came to tell Naruto
about the intensive 2 and a half year training he was taking him on.
Gamabunta - Gamabunta is the king of all frogs. He was
summoned by the 4th Hokage to battle the Kyuubi, by Jiraiya when the 3
Senins battled, and by Naruto during his teaching of the Kuchiyose no
Jutsu and battle against Shukaku.
Gamaken - This is another one of Jirayia's toad
summons which he calls upon in the battle with Pain. Gamaken carries a
large shield and staff with a split spiked end.
Gamakichi - Extremely small compared to the other frog
summons, Gamakichi is the son of Gamabunta and was summoned by Naruto
by accident when he attempted to summon Gamabunta during the Shukaku
fight.
Gamatatsu - Gamatatsu is another extremely small frog.
He is the son of Gamabunta and brother of Gamakichi. He was
accidentally summoned by Naruto during the fight with Shukaku and was
also summoned in the first episode of the series. It is safe to say, he
is the dumbest of the frogs summoned.
Toad Sennin - These two toads named Ma and Pa are
advisors to the Elder Toad Sage. They have to ability to combine with
Jiraiya. When they do, Jiraiya becomes much stronger and has the
ability to use the toad's jutsus.
Turtles
Nin Kame - A Normal-sized turtle summoned by Gai, Nin Kame is able to talk and seems to direct Lee when Gai is not around.
Umibouzu
Umibouzu - Amachi summoned this Umibouzu (sea monster)
to help him terrorize the Sea Country. Something more than sea water
and something less than a sentient being, the Umibouzu is a moving
water technique that obeys Amachi's command.
Weasels
Kirikiri Mai - Kirikiri Mai is a weasel-like creature
that is summoned by Temari during the fight with Tayuya. It can fly and
carries a sickle that cuts everything in its path. This creature was
actually taken straight from Japanese mythology.
