The Prince of Pandas - adventure time OC

My first OC!!!!
This is the Prince of Pandas
Name: Lei, the Prince of Pandas
Gender: Male
Age: 100 (10 in human years)
Lives: The Giant Bamboo groves in Ooo, was originally from a different dimension
Weapon: family sword and pyrotechnics
Lei comes from the royal family of the Panda Nekos, I am his Sister (age 18 actually 180) who is heir to the throne. In the Panda Neko society only the females are allowed to lead the kingdom. The land is mostly Bamboo forests, the Panda Nekos are a tribal race that hold intelligence and fighting ability in the highest regard. Lei is a mischievous little Panda who always got into trouble by playing pranks (which mostly consisted of blowing stuff up/arson, yes he is a pyromaniac). At the age of 10 (100) he realized that he wouldn't be inheriting the throne so he ran away. He managed to steal the family sword and the bottomless bag (bag that has no bottom and can carry anything). While he was running away just before he was caught by the royal guard he fell into a worm hole and landed in the Giant Bamboo groves of Ooo. Using the resources he had around him he built a tree house. One day when Princess Bubblegum was collecting bamboo samples for research she found Lei. Lei called himself ruler of the land, so in order to set up a diplomacy she gave him a crown that matched his pendant (which was the sign of his royalty back in his own dimension) and he was deemed "The Prince of Pandas". Now he looks after the Bamboo and wonders Ooo playing pranks on people and setting stuff ablaze.
Some people call him a villain, but he is a rouge for life!
