Reshiram

Reshiram (often nicknamed Reram or Rea) is a (female) white fire dragon, and Legendary with a hot temper to match. They are said to assist those who pursue the truth over all else, leaving Rea vulnerable to gut instincts like revenge always being the right answer, and once she gets to a certain level of anger, very few people can calm her down. She is part of the Energy Trio, alongside Zekrom and Kyurem.
