Five Most Powerful Giants in the Yggdrasil

Summary and Yggdrasil
Yggdrasil is an immense mythical tree that plays a central role in Norse cosmology, where it connects the Nine Worlds.

A Jötunn, some times anglicized as Jotun (pronounced yōtən), plural: jötnar or Jotnar, is a giant in Norse mythology, a member of a race of nature spirits with superhuman strength, described as standing in opposition to the races of Æsir and Vanir, although they frequently mingled with or were even married to these.
