1.) Naruto grows up knowing his heritage but also knows its a secret.

Main fighting style is taijutsu, fuinjutsu (sealing arts), kenjutsu (dual swords)

bloodline ~ Elemental Chakra chains

fire chakra makes them red hot

wind chakra lets them cut or slice

water chakra makes them more cold and flexable

earth chakra more sturdy and solid

lightning chakra gives it a shock and paralyse ability

When they first awaken there normal chakra chains he has to learn his elements like any other ninja (natural main affinity Wind from is father Secondary affinity for water from his mother)

2.) Gray Naruto He isnt happy go lucky with sad thoughts he keeps locked away like in canon but hes not Evil either he loves the people that loves him and the village because thats his home but besides that he minds his own buisness and sneak around threw the shadows growing up (if he gets kicked out of somewere he waits for it to close and steal it at night) He likes to read and people think hes lazy like shikamaru but he just doesnt care more like a mix of kakashi and asuma

Average talent not a prodigy just smart and level headed and he uses fuinjutsu/kenjutsu to honor the his lost clan (uzumaki his namikaze name is just a family name no clan)

Fox summoner

no bloodline just hightend senses from the Fox summons they share a bond with him (like the inuzuka clan for any kid naruto has they recieve a partner for life)

Apperince: Minatos hair color but kushinas type of hair (like a blonde inuyasha) and eyes are slit but still blue and after he signs the contract and bonds the Uzumaki-Namikaze family to the Demon Fox clan he recieves a mark on his cheeks and a half moon on his forehead (sesshomaru but in ruby red)

3.) Strong Silent type. confident but not overly cocky. Doesnt talk much (more then shino/sasuke less then kiba/canon naruto)

He has sharp nails only get long when added chakra to them. He finds out some things about his lineage during his academy days.

Uzumaki clan gives him a slow healing factor (kyuubi chakra just speeds it up if life threatning) and dense chakra (only uzumaki women recieve the chakra chain bloodline)

Genetics: Red hair and red or voilet purple eyes

Namikaze clan bloodline gives him a tougher body called (the lions hide "skin") but when his blood finally fully activate during puberty theres only 2 body type he can recieve tracker/hunter body lean but with hard muscle Gifted for speed (Minato). Gaurdian/protector body sturdy more muscular Gifted for heavy fighting (Jiraya).

Gentetics: wild spiky hair that frames the face in the front. Golden blonde or Bone white in color (called the lions mane)

Lion summoning contract lost back in the first ninja war havent been found

First Lion summoner since his great great great grandfather. Recieved the lost scroll by trying to summon a toad in excitment before signing the contract his grand father jiraya had

Apperince: Minatos face (plus the whiskers) jiraya length hair but blonde with Red highlights and roots. Eyes red like kurenai but with a voilet purple ring around the pupil. Body type tracker/hunter.
