"Summons that Akuma can Summon"
Summoned Creature: Hidden Shadow Snake Hands
Rank: C
Appearance:

Spoiler:

Description: This technique allows the user to eject snakes from their wrist or sleeve, usually after a punching motion. The snakes are used primarily to attack from a distance and, being snakes, can inflict multiple poisonous wounds on the victim's body or hold them in place. The snakes can also open their mouths to extend Kusanagi-like blades.

This technique can also be classified as a variation of the Summoning Technique. This technique can also produce snakes from different parts of the user's body, as seen when Orochimaru created a snake in his mouth to attack the Third Hokage during their battle.
Jutsu:

Summoned Creature: Many Hidden Shadow Snake Hands
Rank: B
Appearance:

Spoiler:

Description: By increasing the amount of snakes summoned with the Hidden Shadow Snake Hands, the diversity of this ninjutsu is increased. The swarm of big snakes appear in an instant, each snake individually doing something like intimidating, diverting, or capturing the enemy in a cooperative attack. Without giving them the time to react, the enemy is entangled.
Jutsu:

Summoned Creature: Snake Authority Spell
Rank: C
Appearance:

Spoiler:

Description: The user summons two big snakes which crawl out from one's sleeves, and coil around the enemy capturing them. This is a great technique for capturing someone alive, or for inflicting damage by constriction, and if the situation calls for it, the snakes can bite the victim with their poison fangs. With the summons specified beforehand, the procedure can be shortened by using blood on a summoning "contract seal" (結印, ketsuin), making it possible to use the technique immediately. The further addition of the user's murderous intent can weaken their target's resolve.
Snakes summoned by this technique are on a whole other level in terms of intelligence and strength, compared to normal summons. It is said that even shinobi with great skill are unable to escape from this restraint.
Jutsu:

Summoned Creature: Formation of Ten Thousand Snakes
Rank: B
Appearance:

Spoiler:

Description: With this technique, Orochimaru can release a torrent of countless snakes from his mouth, forming a wall of snakes. The snakes will then rise and rush towards his target, being almost impossible to stop or evade. While crawling together the snakes form a defensive wall blocking almost any attack. The snakes can also open their mouths to extend Kusanagi-like blades.

Jutsu:

Summoned Creature: Manda
Rank: A
Appearance: He was coloured purple, and had black rings running down intervals on his body. He had massive fangs, though they were arranged in a way similar to that of a constrictor snake instead of a viper or other venomous snake species, presumably carrying venom in them from the way they were designed, and green eyes. He also had four horn-like protrusions on his head.
Description: Manda was the largest snake in the world, being recently out-sized by his clone, Manda II He can easily tower over buildings and trees. Also known as the king of snakes. He is not that trustworthy and only ably to summon when the summoner gains his trust.
Jutsu:

Summoned Creature: Manda II
Rank: A
Appearance: Manda II is even larger than the original, almost the same length as the Island Turtle, making it one of the largest summons so far in the series. It also has four appendages similar to arms with four clawed fingers along with a cobra-like hood and a rattlesnake's tail. Manda II's teeth also take on the form of a poisonous snake's fangs, resembling those of a cobra while Manda's teeth took on the form of constrictor snake's teeth. He has the same dark markings over his eyes as the original Manda. In contrast to the original Manda, which was based more on a anaconda-like constrictor, Manda II has a mixture of features from many types of snakes and even oriental dragons.
Description: tHIS manda is more like a mix of a python and a dragon. Created from cells from Manda and scientific experiments. Manda II has four legs making him seem some what of a dragon. Manda II is capable of causing more destruction and does more damage then Manda. It is said that Manda II can take out the Giant Island Turtle with ease but no one knows for sure.
Jutsu:

Summoned Creature: Art of the Eight Headed Serpent
Rank: S
Appearance:

Spoiler:

Description: This is a very strong summon to master. It causes eight white snakes to be summoned. These snakes are massive and is rumored to be equal in hight and power as Manda. For some one to even have the ability to summon these snakes they have to have 100% trust from the snakes and be at least a S rank ninja. These eight snakes are far more none trustworthy then Manda and will some times try to betray the summoner. These eight will put the summoner to a test before they will even begin to have some small loyalty.
