I can use different bodies to see all zones with no blind spots and each body has its own unique ability:
First Body (Yahiko)
Pein's first observed body is that of his childhood companion Yahiko, possessing medium length spiky hair six piercings on each ear and a metal bar piercing through each ear, three piercings through the side of his upper nose and one spike stud on each end of his bottom lip. This body is apparently his preferred form for interacting with others since it has participated in all sealing rituals and was seen in several flashbacks by Rain village members. This body has the ability to control rain, and can conjure and stop it at will, even maintain it for long periods of time.[9] This is apparently tied into his mood. In addition he can detect the movements and chakra levels of people travelling within the rain, making it difficult to infiltrate the Hidden Rain village by stealth
Second Body
A thin Akatsuki member summoned by Pein with orange hair, various piercings and Pein's Rinnegan eyes. He shares his vision with the second human summon and Pein himself. He also uses primarily taijutsu and is very fast.
Third Body
The third body is a fat, bulky man with six spike stud piercings covering his entire bottom lip, two studs vertical on the front of his nose, two spike studs one on each cheek, a metal bar going through each ear, and a stud on his shoulder one on each side close to his neck. He is a defensive body, somehow capable of absorbing any ninjutsu related technique, even an over-sized Rasengan and a combination elemental attack with no sign of injury. Originally this body was from Kusagakure.
Fourth Body
The fourth is a tall slender man with very long loose hair, a diagonal bar though his nose, two studs vertically on each cheek, two studs horizontal from each other on his upper chin, and a stud on his shoulders near his neck. Apart from some hand to hand combat this body's abilities remain obscure, largely because Jiraiya damaged his eyes early on in the fight. However, during this fight, he placed his hand on a pipe and was able to instantly sense Jiraiya's location, suggesting he may have some sort of tracking ability. This body was originally from Takigakure.
Fifth Body
The fifth is a tall bald man with a very unusual body shape, possessing a very thick neck, a big square shaped jaw, with a large ring piercing on his nose, spike studs all around his head, and an enormous spike stud on his chin. He can somehow detach and fire his left arm like a missile for long range attacks, capable of shattering stone on impact. This body is also implied to have torn off Jiraiya's arm when he ambushed him.
Sixth Body
His sixth body is a stocky muscular man with a spiky mop of hair, triple bar ear piercings, a stud on his upper nose, a stud on his shoulders near his neck, and a row of studs diagonally down each cheek. This body's abilities and origin remain a mystery although it is speculated that it may have something to do with the resurrection of Pein's fatally injured bodies.
I can also summon many animals that share the rinnegan:
Crayfish
A giant crayfish that can spew a jet of bubbles from its mouth. It was one of Pein's first summons.
Hell Hound
A summoned creature with similar abilities to Cerberus the Hound of Hades. Jiraiya had a hard time combating this creature because every hit seems to make it stronger and grow more heads. The heads would then split into more hell hounds.
Bull
a bull that uses its strength to fight
Chameleon
A giant chameleon with a tail in the form of a snake, small wing like appendages on its back and a horn on its head with several spikes pierced through it. The chameleon has the ability to turn itself completely invisible
Hard Beak Bird
a bird i can fly on
Other summons:
Demon Sealing Statue
The giant statue is used to extract and seal the essence of captured tailed beasts. Each member stands on one of the statue's fingers and perform the sealing jutsu: Illusionary Dragon Nine Consuming Seals to begin the extraction process. Once a tailed beast is extracted, it is consumed by the statue and one of its nine eyes is opened.
Regular jutsus:
Fuuton: Cyclone Blow (Ninjutsu)
Reppushou. Cyclone Blow was used by Nagato to create a surge of high wind that can be used to supercharge the speeds of throw projectiles. Theoretically, it can also be used to deflect incoming attacks
Body Switching
The mechanics behind this ability/jutsu is still not clear, but it is likely something to do with the Rinnegan. Pein can readily switch bodies between one of six stored in stasis-like states; each is said to be suited for a particular type of mission.
Illusionary Dragon Nine Consuming Seals (Seal) (Special)
This jutsu creates nine illusionary dragons from the statue's mouth which crash into and envelop the demon beast host. The extraction jutsu requires all available Akatsuki members to be present. It also requires a large amount of chakra and usually several days to complete. Once the tailed beast is extracted, the human host will die.
Shapeshifting Technique
This technique was used by Pein, to keep intruders away, while they sealed of Shukaku from Gaara. It involves a person giving up 30 % of ones chakra, in order to transform someone into a perfect clone of them, with all of their abillities, weapons, strength, memories and personality. However, since the clone is dependent on the given chakra, they can't use major chakra draining techniques. Once the clones are killed, or uses up their chakra, they will revert to their original form. This technique was used on Yura and another unnamed Sasori underling and transformed into Itachi Uchiha and Kisame Hoshigaki respective. Later on when the fights where over, Zetsu "disposed" of the bodies, presumably to keep the secret of the technique
Gale Wind Palm
Fuuton • Reppushou is a Ninjutsu technique utilizing the Wind Element. After forming the needed hand seals, Nagato will send a strong gust of wind towards his target. When acting in conjunction with another thrown weapon, the wind can increase its power and deadliness.
Pain's Absorption Technique (Unnamed)
This unnamed Ninjutsu technique allows Pain to absorb the substance of incoming attacks. Pain can apparently absorb both plain chakra and elemental attacks and effective nullify them.
Pain's Chakra Detecting Rain (Unnamed)
This unnamed Ninjutsu technique allows Pain to blanket a wide area with a downpour of rain. He can maintain a connection to the rain and tell when someone is obstructing it. This also allows him to detect the individual's chakra level and skill.
Rain Blind
Kouu Buraindo is a jutsu for a quick escape. Upon executing the hand seals for this technique, a flash rain appears, coming down in sheets, to blanket your getaway. Repeated users of this jutsu are fond of using Kawarimi to replace them with a splash of water. The flash rain may catch you off guard and daze you for a moment, even if you expect it.
Rain Bomb
This is a dense, hard ball of collected humidity from around the air. It can be used as a makeshift shield to absorb kunai and shuriken, or utilized as an offensive weapon. Once it impacts upon a target, it explodes into many droplets of water charged with chakra. Therefore, the raindrops are akin to fragments of metal until the chakra is dispersed into the air. A lot of water is drawn out of the air, especially if Kouudan is used consecutively, and, as a result, more humidity techniques are difficult to use. If the jutsu was used in a dry area, it would be even harder to do so.
Rain Bullet
Only usable while raining, this jutsu causes the raindrops around it's user to shoot at a designated target at high speed. Stops after a short period of time.
Rain Clone Teqhnique
Only usable while raining, this jutsu is a weaker version of the Mizu Bunshin. It can attack, but is far weaker than its creator and dissipates in one hit, or when the rain stops.
Bolt Shock
An advanced form of Raiton that uses chakra to increase the amount of bio-electricity in the brain and sends the excess down to the hands in order to form advanced Raiton techniques.
Bolt Sword
A technique utilizing an advanced for of Raiton. After drawing out the bio-electricity focused in his hands, Pein can form swords of this electricity in front of his palm. The borutou, unlike the boruken, can be grasped by Pein, and he will remain unaffected by the bio-electricity. The borutou do cause actual damage to a living opponent, and are strong enough to cut through steel. They have the side effect of causing one to become temporarily paralyzed. The paralysis lasts for five seconds.
