Zagtar

Zagtar, defender of space, was a giant warrior robot who was destroyed by the Evil Wizard. Amy suggests the Planet Express crew summon Zagtar, before Hermes reminds her of Zagtar's demise.

Whether Zagtar is a canon or non-canon character is not known, and will depend on the style of the "Reincarnation" episode.

Production
Zagtar was first seen in the storyboard of "Reincarnation", released by the Countdown to Futurama on June 13, 2011.
