Oktavus

Oktavus is the father of Ursula's non-canon son, Orson, in The Little Mermaid 2 reboot.

He doesn't make an appearance in the story and is only mentioned, though Orson's description of him is solely based on what Ursula shared, as he never got to build a relationship with his father himself.

He was created by VampireMeerkat and made his first online appearance at Tumblr on May 20, 2019.

Personality
Oktavus is a joyless and serious person, who finds it difficult to interact with others. Because of this, it took him 10 years to push through and officially ask Ursula to be his partner. Her sly demeanour and respected title as witch of the sea spoke to him, but when he got acquainted with her "loud stage actress" side, his attraction for her dwindled. He wished for her to be more like him, while Ursula preferred he developed a sense of humor.

Their son was born from love, but Oktavus' patience with Ursula had ran dry after he was only 2 years old, whereafter he also started to criticize her increased weight and use of flamboyantly coloured make-up. As the young Orson showed a clear preference for his coddling mother, Oktavus believed there was no reason to stick around and erased himself from his family's life.

He never returned or felt regret, insinuating he can't emotionally attach himself to anyone.

Appearance
Oktavus is a muscular octopid with long dark-blue hair, long sideburns, thick eyebrows, and a goatee. His eyes are blue, he has a bony nose, and large spots on his shoulders. He's never seen smiling.

His no-nonsense looks are what drew Ursula towards him.
