Eras (エラス Erasu) is the main antagonist of the 2019-2020 Super Sentai series Kishiryu Sentai Ryusoulger

She is the ruler of Druidon Tribe, a race of monsters bent on conquering the world and destroying humanity. She is the entity who created all of the Druidon generals and as such is referred to as the Mother of the Druidons by the generals of the Tribe. Her existence only seems to be known to them, as the lower members of the tribe (like Kureon) were unaware of who she was and did not recognize her name initially. 

She is revealed to be sealed underneath the crust of the Earth, and only pulling out the Ryusoul Calibur could awaken him. Eras is referred as master by both of the active lead Druidon Generals on Earth, Pricious and Wizeru.



Nothing much is known about Eras or where she came from. She is the master of the Druidon Tribe and the one who created the Druidon. 65 million years ago, Eras one who led the Druidon Tribe in their invasion of the Earth, only for them to be fought back by the Ryusoul Tribe. She was eventually sealed within the crust of the Earth by the Ryusoul Masters and was left their after the rest of the Druidon Tribe retreated into space following the extinction of the dinosaurs caused by meteors crashing into Earth.

In modern era, the Druidon Tribe returned back to the Earth in order to reclaim it. After the second and final death of Gachireus, the Druidon generals on Earth had been discussing about RyusoulCalibur. Pricious revealed that as soon as Ryusoul Calibur was pulled out, the Great Power of Druidon would be awaken. Wizeru then realized that Pricious intended to revive Eras. Kureon, who attempted to become a top general of Druidon, was displeased when he learned about Eras' existence and decided to eradicate Ryusoulgers in order to get promoted.

During her time sealed, Eras fused with the Ryusoul Calibur and was slowly draining its power, causing Setoh to instruct the Ryusoulgers to go and retrieve it before Eras drained the last of its power. Eras' sealed state was later discovered by Master Black, who found that Eras had fused with the Earth itself, enabling her to regenerate from the planet even if she was destroyed.

After excavating the site where Pricious was sealed, Pricious asked Eras to add a new general to the Druidon's ranks. With her revival already imminent, Eras created the general Gunjoji to aid Pricious in fighting the Ryusoulgers. Gunjoji was soon followed by an identical "little brother", Gunjoji II.

Eras eventually created a new Druidon general soon after, Yabasword.

As Eras' revival became imminent, Yabasword went berserk and started attacking both the Druidons and the Ryusoulgers before growing giant and attempting to destroy anything in his path.


  • Eras' debut is a sphere-shaped core, similar to previous villain leaders including Shine and the Omnipotent God, who all took spherical forms and lacked a mobile form in their full appearance. However, it is presumed that Eras would have a mobile full body once she was resurrected.
  • Eras has one of the latest debut appearances made by Super Sentai villain leaders by making her debut in episode 40 of Ryusoulgers and is never mentioned or alluded before that point.
  • Due to being the leader of Druidon Tribe, her chess motif is based on a king piece, the most essential piece on a chess board.
  • Eras is the first female Super Sentai villain since Grandiene to be the main villain of a season.
