Hubert the Goblin

Hubert the Goblin was a main antagonist from Mystic Forest Fighters.

Starting off as a minor villain, Hubert rose to power when he led his army of goblins to assassinate the royal family of the Unknown Side, allowing for himself to take over. He ruled with an iron fist and attempted to enslave all non-goblin species, causing a resistance to form. Although he put up a good fight, he was eventually overpowered and beheaded by Luke, who took over as king.

Bio
Hubert was born as the son of Derei the Goblin, who ruled over the land of Realgon and spoke at the king's council. Derei taught Hubert how to fight and act aggressively, allowing Hubert to grow into a ruthless goblin. To seize control of Realgon, Hubert challenged Derei to a duel, and successfully killed his father. Due to this, Hubert was named the ruler of Realgon and took his place at the king's council. His castle functioned as the prison for dragons in between the Dragon Games events, as well as a home for the protectors of the prison's key. When Herb, a key protector, befriended Gus the Dragon and began plotting to have the Unknown Side overrun by dragons, Hubert was hired to be Herb's personal assistant and connection to the outside world. Hubert agreed to the job as long as the goblins would be spared from the dragon's wrath.
