Galfore was Starfire's guardian and protector in her childhood years, a relationship which created a strong bond between the two. When Starfire returned to her planet for a marriage prearranged by her sister Blackfire, Galfore was the only one to openly express his doubts about the whole affair and despise Glgrdsklechhh, the prospective groom. He was also quick to notice that Starfire was not at all happy with the arrangement because she had clearly given her heart to someone else.
When the wedding, and the Drenthax invasion which initiated it, turned out to be a hoax orchestrated by Blackfire, Starfire challenged her for the crown and defeated her. However, after setting the most important affairs in order, she decided to abdicate because of her affection for her friends (Robin in particular) and left for Earth. But before she departed, she made Galfore the Grand Ruler of Tamaran in her stead, a position which he accepted for the good of his foster daughter.
PersonalityWhile Galfore gives an initial impression of being intimidating and strict, he is actually very kind, caring, and polite. He really cares for Starfire and thus is highly protective of her, even against her friends (simply due to her status as a member of the royal household). He likes to speak his mind and act upon it, though as a retainer he did remain conscious of his own status.
His relationship with Starfire is very close, like between a father and a daughter, and he only has the best interests for her in mind. The extent of this trust between them is proven when Starfire made him Grand Ruler of Tamaran in her stead.
Powers and Abilities
Galfore's powers, if any, are unrevealed, but his hulking appearance suggests that he is super strong. Also, as mentioned earlier in the series as a Tamaranean gene, he may have the power to generate starbolts similar to those of Starfire's.
