The Prince

 The Prince is the 5 cm (In Crossover he's 1 foot) tall son of the King of All Cosmos. In the Katamari Damacy series, Prince is often tasked with rolling magical adhesive balls called katamaris. He is never really appreciated by his dad but is adored by the world over. He joined the Crossover Avengers mainly because he was tired of constantly taking orders from his dad

Abilities
Despite his small size, he can wield a number of abilities with his Katamari (a magical sticky ball), by default rolling up objects and enemies alike, although the Katamari must be sufficiently larger than the targets in order to roll them up. He has two powerful abilities called the Prince Hop, which lets him jump into the air really high, and the King Shock, which draws nearby objects to the Katamari like a magnet. Another ability is the Charge-N-Roll, which builds up power and shoots the Katamari straight ahead with great speed (it’s pretty hard to control at this point though).

Personality
In Crossover, The Prince is displayed as a rather rebellious and troublesome being, always fighting verbally with his dad, The King of all Cosmos (Not to mention always getting in BIG trouble with him. Punishments include but are not limited to: Long boring lectures; Banning of internet privileges; And getting shot at with lasers). He’s quick witted and smart compared to his dad, who is rather fruity and sometimes delirious. The Prince is experienced in the ways of the Katamari, and is never seen most of the time apart from one. Although he may appear the rebel-type, he dislikes violence and prefers to let his Katamari solve problems for him. He also harbours a deep fear of butterflies for some odd reason.

Trivia

 * Prince has a total of 58 Cousins, all of random shapes and sizes. The weird part is that the King has no siblings or family besides his dad, the High King. As such, they may be related to the Queen, but even that is stretching it...
 * Prince possesses an awesome sense of music and dancing, but is very self-conscious about it.
 * In the Katamari Damacy series, Prince is 5 cm tall. In Crossover, he is 1 foot tall. Still small, but big enough so that he isn't invisible.
