King Ashura is a crossover character from RG Veda and should not be mistaken for another crossover character from RG Veda, Ashura-ō, who is this Ashura's son in RG Veda. (Ashura-ō means King Ashura and is a title also used as a name in RG Veda, which both of these characters bear, though there the son is usually referred to as "Ashura".)

* Age: 12-13 in Part I, 15 in Part II
* Rank: Chunin
* Seiyu: Nana Mizuki

Hinata Hyuga (日向ヒナタ, Hyūga Hinata?) is the eldest daughter of the Hyuga clan's main branch, and thus is the heiress of the clan. Her father trained her to use the clan's more basic abilities such as the Gentle Fist style of combat, though in time he came to deem her a lost cause and left her to train by herself. Throughout her early time in Team 8, Hinata's lack of self-confidence and unwillingness to fight bring her failure in every mission she is assigned. In an attempt to change herself Hinata enters the Chunin Exams, where she is forced to fight against her cousin, Neji Hyuga. Her efforts eventually allow her to acquire a better relationship with her father, who encourages her to continue working on improving herself.

Hinata has a long-standing crush on Naruto Uzumaki, which has been present since their time in the Academy. Her feelings for him are rooted in his determination, confidence, and strength, all of which she feels she lacks. Despite her rather obvious feelings, Hinata has yet to openly admit that she likes Naruto, though many characters have been shown to be aware of it. Similarly, Naruto has remained completely oblivious to Hinata's feelings, though he has come to enjoy her company more than he once did. Hinata tends to break away from her usually timid self when around Naruto, such as going out of her way to help him or putting more effort into something because he is nearby. She also becomes more assertive on Naruto's behalf and never hesitates to defend him, even to himself. Naruto also acts as a key component in her quest to better herself, as she trains so that she can be like him and impress him at the same time.

A charming and optimistic mercenary who travels with a white bird (of unknown spieces) named Kurruku. Kotona's real name has yet to be revealed, she's only using an alias. Although preferring to use her beauty and diplomatic nature to avoid conflict. She joins Ruuji in his quest for a generator mechanic as a way to repay him for his help in defeating a group of Zoid thieves.

She was brought up to be a skilled assassin and has many weapons hidden on her body. It was later revealed that her people are actually part of a surviving group that avoided the "The God's Fury" event and rebuilt their society at Iron Rock. Throughout the years her people began to forget their origins, but a small group of them has kept the secret for generations as custodians to the city and to their sleeping Gil Dragon. She knows various ancient phrases passed down by her mother and that her real name is actually the Gil Dragon's activation codes. No one can know her true name unless it's her husband.

She pilots the Zoid Rainbow Peak. Her Japanese VA is Shizuka Itoh. Her English VA is Julie Ann Taylor.

Rider is a fictional character from the Japanese visual novel and anime series Fate/stay night by TYPE-MOON.

She is the Servant of Shinji, first seen scouting around Homurabara Gakuen. Rider is silent, sultry, and vigilant, never hesitating to shield her Master from harm. Her weapon of choice is a pair of long iron nails fastened to opposite ends a single chain, which she effectively thrusts from distances.

Teletha "Tessa" Testarossa is the charming and clumsy Captain of the revered TDD-1 Tuatha de Danaan submarine of the anti-terrorist organization Mithril. She is American by birth but has lived on submarines and military bases for the majority of her life. She was born on December 24, 1985 and is a child prodigy who rose to such a high rank at the age of only sixteen. She has platinum/silver hair and gray eyes. Later revealed as being a Whispered, her high level of mathematical and scientific adeptness is dwarfed only by her brother's, which seems to have given her a sense of inferiority. Though not very athletically inclined, but has shown to be a very good swimmer (as shown in episode 8 of Full Metal Panic? Fumoffu!). She has an interest in Sousuke that extends beyond a professional one, generating a love triangle she shares with Sousuke Sagara and Kaname Chidori. Even though Chidori and Tessa seem to compete against each other for Sousuke, they are good friends in reality, as during several episodes they talk about Sousuke and his unique military charm.

Yōko (ようこ, Yōko)
Yōko is the female lead of the show. She has two main abilities. The first is jaen (likely 蛇炎, meaning "serpent blaze"), where she shoots a coiling strand of fire out of her fingertips. There is also dai-jaen (likely 大蛇炎, "mega serpent blaze"), which is just a larger, more powerful variation. The second ability is shukichi, an ability which allows her to teleport objects. Strangely enough, although she is generally fearless in the face of evil spirits, she is terrified of normal dogs. Later on in the series, it is revealed that Yōko is not an Inukami at all, but rather a kitsune (which would explain her fear of dogs; foxes and dogs are natural enemies) and the daughter of the legendary Dai Yōko. During an escape from Hake she met the child Keita, who was with her for three days and shared his chocolate cake with her, which became one of her favorite things. Due to this incident, she wanted to become Keita's Inukami to make a contract with him.
