Serpa is Fu-Xi's son. He has black scales, red markings, and blue eyes. He also has small, needle-like fangs.

Serpa was born to Fu-Xi, who had escaped from prison, and his wife who passed away shortly after Serpa was born. Fu-Xi was captured and taken back to prison with his son. Shortly after this, Serpa grew a strong friendship with the other kids in the nursery and helped them escape from the prison. Serpa worked as a dancer and performer for the villagers of the valley of peace and eventually caught the attention of Bush and Meadow who were impressed and joined in on one of his performances. Serpa was eventually accepted into The Dragon Knights.

Like his father, Serpa sees himself as a defender of snakes but believes he and "two-leggers" can be equals if the two parties will give each other a chance. Serpa is brave, noble, and kind. He knows a lot about poisons but prefers not to use them on anyone, even on enemies.

Serpa always wanted to make his father proud by avenging the Serpas but didn't want to end up like him.

Serpa, Meadow, and Bush have a strong friendship with one another.

He also looked to Viper as his motherly figure.

Trivia:

Serpa is named for his species.

Serpa has not bitten anyone in the show, onscreen anyway.
