Taiyang Xiao Long

Taiyang Xiao Long is the father of Yang Xiao Long and Ruby Rose. He is mentioned to be a teacher at Signal Academy on the island of Patch where the girls grew up.

Appearance
Taiyang is a man with blond hair and lilac eyes who also has a tattoo on his right arm. He wears brown cargo shorts with a dark brown belt, black shoes, and a brown leather vest over a tan dress shirt(that has it's right sleeve cut off). For armor, he wears a metal spaulder, leather vambrace, and a brown fingerless glove. All on his right arm.

In his younger days, he didn't have his tattoo and wore brown cargo pants rather than shorts.

Personality
Taiyang is said to be a bit overprotective by both of his daughters, yet still open and caring. His attitude towards helping others in need was shared between his spouses and was passed along to his children too. He appears to have an eccentric side, as he is stated to do things like send the family pet Zwei through the mail all the time.

During his period of mourning the disappearance and possible passing of Summer Rose, Yang said he "shut down", showing that he valued her presence greatly and was devastated by her loss. His over-protectiveness of his daughters likely stems from both this and the incident where they were almost slaughtered by Beowolves, had their uncle Qrow not been around to save them.

Given his eccentric side, the fact that he decided to train Yang as Ruby said in Round One, and the fact that he let both of his daughters become huntresses, it's likely he managed to move on from his emotional breakdown to become a better father.

Trivia

 * The Chinese transcription of his name, Tàiyáng Xiǎolóng (Simplified: 太阳小龙; Traditional: 太陽小龍) can be translated literally to "Sun Little Dragon". This has the same literal meaning as Yang's name; the characters tài yang (太阳) together mean Sun. tài (太) on its own can be a grammatical intensifier analogous to "very", or an adjective roughly meaning "excessive", "big", or can be used to refer to elders within the family, which gives the possible translation of "Elder Yang Xiao Long".
 * Taiyang is the second family member within Ruby and Yang's family to be a professor at Signal, along with their uncle Qrow.
 * Taiyang shares his color scheme with his daughter, Yang.
 * It's stated he taught Yang how to fight.
 * It is unknown if he was married to Raven or Summer, meaning that Yang and/or Ruby might be illegitimate children.
