Acidicus is a minor antagonist in Ninjago. He is the General of the Venomari Tribe.
He is the Serpentine General of the Venomari tribe, he has white spikes on his head, tusk-like fangs, and four yellow eyes. His body is dark green with black, red, and lime green markings.
The most intelligent member of the Venomari, Acidicus is responsible for most of his tribe's battle plans and schemes. He also invented special vials that can safely and effectively store Venomari Venom, ensuring that his forces never have to worry about running out of venom in battle. Following their reform, he serves as an elder of the Serpentine.
- He has a similar headmold to Lizaru, but with white spikes on his head instead of green.
- In concept art, Acidicus's weapon (the Hypnobrai Fangblade) has a gold blade instead of the proper silver color.
- Several cards seem to give Acidicus a prominent leadership role among the Serpentine, as he is depicted at the head of an army of Serpentine.
- In The Curse of the Golden Master, his Venomari Staff is now emerald instead of golden. In addition, it no longer has the Anti-venom. Hovever it should be a different staff.
- In the same episode, he is called the "Chief".
- He may have not always been a Serpentine general due to the fact that he said "I've fought hard for this staff and will not give it up easily." in the show.
- Acidicus's name is a pun on the word "acid."
- Acidicus is a playable character in LEGO Ninjago: Tournament.
