"Okay, Ace. What do you need?"
Strengths: Empathy, Helpfulness, Casting in a Pinch
Weaknesses: Size, Following Orders
Abilities: Cubbins has demonstrated his ability to do small object conjuration (pulling things from a hat). In a more drastic example of this he is shown to "pop a cap" by using powerful conjuration from his hat offensively.
He is a slight man with hair flipping out into wings on both sides, a baseball cap, collared short-sleeved shirt, and pointy elf shoes.
As Tower of Jenga succumbs to siege from Gobwin Knob's purple dwagons, Cubbins defies an order to take a flying mount, instead sending an archer in his place and remaining on the tower to blow off all the tower defenses, to devastating effect. He was trapped and incapacitated in the rubble of the tower, until Ace Hardware rescued him. Ace then used his jetpack, modified to have an 'autopilot', to send Cubbins to meet up with Pierce so that he could be healed.
Cubbins is likely responsible for the magic hats Jetstone uses for communication.
Apart from Prince Ossomer, the Hat Magician Cubbins was the only unit at the court of Jetstone who was friendly to the Dollamancer Ace Hardware. Cubbins would spend some of his juice on small object conjuration to produce items that Ace could enhance and enchant to accessories using Dollamancy.
It is implied that the relationship between Cubbins and Ace was romantic.
Real World References
Cubbins is a reference to Bartholomew Cubbins, a character of Dr Seuss's creation. The character met his king, and removed his hat in respect. Another one appeared on his head. The king, mindful of this disrespect, tried to have his hat removed, and eventually, tried to execute him. The executioner couldn't kill him as it was a rule you had to remove your hat. He kept removing them, new ones appearing on his head. After the 451st one, they started to become more beautiful and gilded, till he reached the 500th one. It was so beautiful that the king merely bought his hat for 500 golden coins rather than throwing him off a tall tower.
Additionally, Cubbins' costume (and his slight stature) are oblique references to the uniform and appearance of a Cub Scout. His costume does not correspond exactly to the Cub Scout uniform; for example, Cub Scouts do not wear sashes or pointed shoes.
