Jeffrey Dragonheart is the main character of the Jeffrey & Friends' Adventures and the Jeffrey & Friends' Storm Adventures series.
He's a young 21 (currently 23) year old human/dragon hybrid kid who dreams of seeing other worlds. So he decided to go and see other worlds, taking his friends Nathan, Mitsuki and his Pokemon Pikachu and Meowth with him.
Jeffrey is brave, kind, gentle, generous, funny, loyal and friendly. But he can also be pretty tough to handle. He can also be somewhat tempermental sometimes. He's also very shy and somewhat timid at times. Jeffrey is also the patriarch to the team. Because of his position, Jeffrey is sometimes called the "King of the Justice Guardians." In another life, Jeffrey was a pet dragon to the Supreme King that the King found caught in a dragon trap and freed him from it. After his kind gesture and growing to like the Supreme King, the dragon decided to be the King's pet and the King named him "LegendWings". One night, LegendWings made a wish to the Blue Fairy to always protect the Supreme King, and it was granted. Eons later, LegendWings became Jeffrey in another life and the Supreme King became Jaden.
He's also a excellent cook, so he and Mitsuki basically cooks for the team. But there are times when he tends to eat at random moments. (In other words, he tends to "think with his stomach".) Jeffrey is also an intelligent person and is a great inventor. In fact, he was amazingly born with his intelligence and super strength! No one knows how this happened. Some believe it was genetics and others believe it was some type of magical force. Whatever the case, Jeffrey was considered "one hell of a gifted child".
Thoughout the adventure series, Jeffrey has made many friends. Some of his new friends even joined his adventure team.
When angered, Jeffrey can transform into a dragon species known as the Skytsengel (which is a extremely rare species). In this form, he is very strong and powerful, stronger than Set. Dragon-Jeffrey eventually chooses Jaden to be his rider. But even if he doesn't turn into a dragon, Jeffrey can still be dangerously scary when he's angered by some reason, like for example, someone hurting Xion.
Another part of Jeffrey is how he feels strong sadness for the deaths of characters like Mufasa, Littlefoot's mother and Bambi's mother since he doesn't want young characters like Simba, Littlefoot and Bambi to be orphans.
As a human, Jeffrey is a very strong young man who he has spiky black hair, green eyes, wears a dark red shirt, black colored jean pants, white socks and black colored slip-on shoes. He also has a scar on his left eye from fighting a Zip Slasher Heartless when he was 8 years old.
As a dragon, Jeffrey becomes as big as Smuag. He has black colored scales, red colored belly, big wings, silver colored claws, black spiky hair, a big tail with a shape of an Ace, and has the same scar on his face. Jeffrey also becomes very obese in his dragon form.
