Reshiram

Reshiram is a Legendary Elemental from Mountain Empire. He used to be the crown prince of Viur.

Appearance
Reshiram is a tall dragon with long, white and red hair and blue eyes. Nowadays he's wearing a white Cardigan and wears his hair in a braid.

Personality
Reshiram is a kind soul who loves flowers and baking. However, he used to be a ruthless ruler who would kill without hesitation to get what he wants.

Story
Reshiram and Zekrom were adopted by King Gropius after they have been taken away from their biological father. Reshiram was chosen to take over the Kingdom after King Gropius passed away from old age. Reshiram was told to unite Phoenie under his hand - and he did, or at least he tried.

This is when the events of the Great War took place.

The freedom fighters chose not to kill Reshiram, despite all the chaos he had caused. Instead, he and his sister were punished into the darkest prison in the underground of Kingdomestaat. His castle was reworked into a university, and no one has heard of him or his sister since.

Cameos
15 years after the war, during the events of Phoenie's New Hope, Miki and Eevan encounter Reshiram and Zekrom in the underground. They help them with dealing with the Dragon Slayers, and manage to escape the underground, moving to a place where no one could find them and prosecute them: The Dragon Mountain. Reshiram took his new life there as a chance to give back to the community, since this was the only thing he could do after damaging the country as much as he did.

Zekrom
His younger sister. She was by his side, supporting him all the time. He always relied on her and she was like his better half.

Xerneas
A young man he taught magic and rulership before he took over the role of the King. Xerneas disagreed with his plans to take over Phoenie, and Reshiram damaged his face and banished him and his sister. They haven't been in contact ever again.

King Gropius
His beloved father, who gave the siblings everything they need and want. Reshiram has always been very loyal to him.

Kyurem
His biological father. The siblings have been told to stay away from him at all costs, since he is a very dangerous being.

Trivia
