Xavier is known for being quite clumsy, as in the "Once Upon a Time" chapter, Jennifer states that he would often slip while the orphans were playing in the mud puddles outside. He also once states that he wants to out eat a pig, as he apparently considers the pig his arch rival.
Xavier is also shown as irresponsible and/or inconscient. Indeed, he is responsible for accidentally shutting the orphanage/airship's power down during 'Rag Princess Sews' chapter, since he tried to take the power lever and use it as a sword.
He is best friends with Nicholas, the only one of two other boys at the orphanage, and enjoys sword fighting with him. Xavier is known for being somewhat mischievous, as he and Nicholas were known for pulling pranks.
In the "Rag Princess Sews" chapter, he causes a power outage by shutting off one of the generators and breaking off the lever, leaving Jennifer in the dark.
The meaning of the name Xavier is "bright; splendid." This could be ironic, as it clashes with his somewhat dimwitted personality and actions.
