Zugu has a unique face print, with purple tattoos surrounding his facial features; these include a thick black unibrow. He has red makeup around his eyes, and a single triangular tooth jutting up from his lower lip. Zugu also has unique torso and leg prints, but shares his shoulder armor piece with Chop'rai. He also shares his bone helmet piece with Chope, Kapau, Krait, and Sleven.
A former Sumo wrestler, Zugu rose up through the ranks of Master Chen's secret army to become one of its two acting generals. His size and strength make him almost impossible to budge - but when he chooses to move, few things in Ninjago can stop him.
After the defeat of the Anacondrai Cultists, Zugu was later revived in Day of the Departed along with Eyezor-both in their Anacondrai forms-to help Chen in his bid to destroy Kai and Nya. The pair attacked using Condrai Crushers, but were ultimately defeated and sent back to the Departed Realm along with their master.
- According to his LEGO.com profile he and Eyezor are Chen's leading generals and Zugu used to be a sumo wrestler.
- In LEGO Ninjago: Shadow of Ronin, he misspelled as "Zumo" which is a pun of sumo.
- His Anacondrai form does not exist as a physical minifigure.
- His appearance with his armour and helmet makes him similar to Shao Kahn from Mortal Kombat.
