Gachireus

Gachireus is a general of the Druidon Tribe and a major antagonist in Kishiryu Sentai Ryusoulger.

History
Gachireus appeared as Wizeru and Kureon were decorating their new base and demanded to know what they were doing. Kureon told him they were just setting up their new war room, but Gachireus stated that if they had time for interior design they could crush the Ryusoul Tribe. Wizeru then got angry at Gachireus bossing him around and attacked him, but Gachireus simply shrugged off his attack. Annoyed at Gachireus' refusal to answer his questions, Wizeru left.

Gachireus and Kureon later observed the Kelpie Minosaur as it battled the Ryusoulgers. Impressed by the Minosaur's success in battle, Gachireus ordered Kureon to create enough slime to make 500 of it. When Kureon complained about the work, Gachireus told him that if he could whine he could do the work.

Later, after the Kelpie Minosaur was destroyed by RyusoulGold, Gachireus appeared to the Ryusoulgers, saying they would soon meet their demise. When they asked who he was, Gachireus stated they did not need to know his name before exiting the scene.

After the Pan Minosaur was beaten back by the Ryusoulgers, Gachireus angrily scolded Kureon for sending the Minosaur out without a plan. Panicking, Kureon claimed that he did have a plan, he just needed more time to finish conceiving it. Later, when Kureon was about to let Canalo's sister Oto go after he shocked KishiryuOh, Gachireus appeared and scolded him for trying to keep his promise. Gachireus then turned to Canalo and told him they would only set Oto free when Canalo was dead. However, Canalo instead used his Eletricity Soul to zap them, sending Oto flying from them.

Back at their lair, Kureon apologized to Gachireus for the failure of the Pan Minosaur, but Gachireus was not concerned about the defeat, stating that he now had a good grasp of the Ryusoulgers' weaknesses. Gachireus then informed Kureon that he had no more use for him before slashing him and heading off.

Leading a squad of Drunn Soldiers, Gachireus attacked the Ryusoulgers and, with his knowledge of their fighting styles, beat down all of them. However, Koh discovered that Gachireus' weak spot was his right chest and, together with Canalo, managed to defeat him by performing a combined attack on it, causing Gachireus to seal himself in an amber fossil. However, unbeknownst to them, this was all part of Gachireus' plan, as the supposed "weakness" was actually a powerup that would make him stronger if it was struck. Once he had finished recuperating, Gachireus burst out of his amber mold and grew giant. The Ryusoulgers summoned KishiryuOh Five Knights to battle him, but Gachireus overpowered them. To gain even more of an advantage, Gachireus dragged KishiryuOh into the sea, where he assumed his submarine form and beat them down. Before he could finish them off, MosaRex joined the battle and attacked him, though Gachireus was not phased as he had already analyzed MosaRex too. However, Canalo had MosaRex transform into Kishiryu Neptune and, in this form, Canalo destroyed Gachireus.
