Zekrom

Zekrom (occasionally nicknamed Zikrem or Zik for short) is a laid-back but caring jet-black dragon, as well as a Legendary, with millions of volts of electrical power stored inside of his generator-esque tail. He is cool and relaxed, but cares for those around him with a passion. He is said to assist those who pursue their ideals of the world, be they possible or impossible. He is a part of the Energy Trio, alongside Reshiram and Kyurem.
