7. Alexstrasza

Series: Warcraft
First Appearance: World of Warcraft: Wrath of the Lich King 

Alexstrasza is given the role of "Life-Bender" as she worked to keep all of the creatures of Azeroth safe. She is not the oldest, but she is one of the most powerful dragons in the Warcraft universe. She has the ability to regrow forests, and she can resurrect the dead. So if this 2012 thing is real, we want Alexstrasza in our corner.
