look up any word, like trill:
 
1.
The force of destruction in our home, Fern Gully, which is the last rainforest, Zak and I are very pleased that Hexxus is no longer a threat to our beautiful home.
We have trapped hexxus with the magical powers of creation and new growth.

2.
The antagonist in Fern Gully, whose goal is to destroy the rainforest. He is the scariest thing ever and gives little children nightmares.
I watched Fern Gully last night and I had nightmares about Hexxus. I wet the bed.
