Hattena is a Player of Team Quval and the main antagonist in episode 12 of the 2016 TV series Doubutsu Sentai Zyuohger. His true body is his cap, which controls the seemingly indestructible Dummy Bio Body. His Blood Game is to steal nearby words.
Hattena holds a Blood Game of his Word Hunt, which would steal every word in his vicinity. The Zyuohgers, minus Tusk, try to attack him but he flees.
Later, when Hattena continues with his Word Hunt, these same four Zyuohgers try to attack him again but this time with their voices and numbers on their Zyuoh Changers also taken as with many words from a bunch of civilians. This also included the book "The Short-Nose Elephant".
Quval mentions that his Word Hunt would leave many people being unable to communicate properly, with Ginis adding that without it, civilizations would fall very quickly. Once Tusk sees him, he tries to attack Hattena but quickly fails. With Tusk unable to understand what his teammates were trying to say while still getting attacked by Hattena, even with charades, Oiwa tells him to aim for his cap.
Hattena promptly de-attaches his cap-like head but Tusk steps on his body and uses Instincts Awakened to slay and stomp on him. Once enlarged with a Continue Medal that's been inserted by Naria (which is right on the top of his head), he then ends up temporarily gaining control of Zyuoh King to shoot Zyuoh Wild, but they remove him from the mecha.
The Zyuohgers then use Wild ZyuohKing to finish Hattena off. Whatever became of his body was unknown.
- His design is very similar to Kimen Doggler from 1987 TV series called Hikari Sentai Maskman and his ability to steal words from anything and anyone makes him very similar to the Word Processor Armadillo from 1983 TV series called Kagaku Sentai Dynaman.
