- "Too bad mannen!"
- ―Meka's final words before death
Meka was the sole surviving member of the Rinjūken Akugata by the events of Engine Sentai Go-Onger. After joining forces with the Gaiark, he stole Long's sealed form from Jan in order to remake the world in his image. He inserted it into the Nunchuck Banki in the hope that he'd be strong enough to destroy the Gekirangers and Go-Ongers so that no-one could stop him. However, he decided to ally with Long when he was revived as Long Banki only to be overwhelmed by Mele, Miu and Hiroto. With Long Banki and Meka knocked back, the Gekirangers summoned the GekiBazooka, the Go-On Wings formed thier Wing Boosters, Ken armed some missiles in his SaiBlade and Gou charged up his GongChanger to fire his Rigid-Rigid Fist attack. They then all fired in unison, destroying Meka who could only bemoan his luck before exploding. Although Long Banki survived it and enlarged, he was soon sealed away again by SaiDaiGekiRinTohja and Engine-O G12 with the Engine Animal Spirit Grand Prix.

The Rinshi (リンシーズ Rinshīzu) are the jiangshi warriors revived by Rio performing the Ringi technique "Rinzai". The Rinsi are in turn led by Mele, who is in charge of their development in some cases, being low-level users in the Akugata, they wear masks formed by a hat and a blindfold and use lances as their weapons. If a Rinshi can cross through the Chamber of Trials, defeating the other Rinshi inside single-handed, he/she can remove the mask and the animal motif on the forehead materializes, with the Rinshi receiving new attire and promoted to the more powerful rank of Rinrinsi who can assume "Beast-Man" form for a tentative amount of time. When they die, their bodies petrify and explode in violent bluish flames.

Rinrinshi can obtain Beast-Man form, but only for a short among of time depending on the level of Rinki amassed inside.
