Robo (Amazing Katamari Damacy)

Awhile back, I discovered a loophole within AKD's storyline. If the objective is to win the Queen's heart back by playing as the prince, and it's an endless game, that means you never win her heart back. That means I can fall in love with her, heheh!! And maybe this time around, she discovers how the King has made the Prince work him in the past, and how pathetic that really was. She wants the prince to have a kind role model, and Robo loves the Queen and the Prince very much. The the Queen marries Robo and they raise the Prince together and they live happily ever after.

Elle (Action Drive)

Elle was once one of the many robots created for the Cosmic Military Force. When it was discovered that a group of scientists on Earth wanted to perform unethical research on the Cosmic race, Elle was appointed as the Queen's bodyguard. However, due to the lack of a threat for a period of time, she was put away. However, she was able to escape confinement and become a commoner. But when trouble arose after she was kidnapped, Elle received an emergency signal and teamed up with the Prince to rescue the Queen. After rescuing the Queen, Elle promised to never let any of her loved ones get hurt again. She stands for justice and now teaches self-defense lessons. When she's not working, she is extremely caring and attentive to her family.

Robo (Action Drive)

Robo is the Queen's wife and the Prince's stepmother in the Action Drive universe. She assists the Prince in finding his mother while giving him emotional support. Robo is a kindhearted robot with a detailed past: Before Robo became a social worker, she was a military-grade robot named Elle. However, she decided to escape the defense force to live with the commoners. Even as "Elle", she had a close bond with the Queen and the Prince. Instead of using force to defend the vulnerable, Robo prefers gently helping and guiding those in need. She was alerted to the Queen's abduction due to an emergency system built into all Cosmic guard robots.

Bluebelle

Bluebelle is the daughter of the Queen and Robo. She is very close to her half-brother, the Prince. Usually, she is found hanging out with her friend Lace or playing with her teddy bears.
