- "The Nightmare Knight himself would be horrified by what lies beneath this hood."
- — The Guardener
The Guardener wears a flowing forest green cloak fastened with a dark green clasp. His face and limbs are covered by the cloak, and he warns that what is beneath the hood is terrifying. Underneath the hood is shown to be a very realistic rendition of a rabbit, rather than the artistic "cutesy" style that Gigi normally uses.
The Guardener is powerful, enigmatic, and shrewd. He was able to defeat Rosemaster, showing that he is very powerful - but Rosemaster was able to curse his followers (Guardlings) away from him. This is revealed to be false, as Rosemaster has been kind to the Guardlings, rather than the Guardener, who shows a lack of caring towards them.
