Karantular

Karantular is the giant spider that Reramos used as a Trump card in the final battle against BoBoiBoy.

Fight for Windara!
When BoBoiBoy and his friends defeated the Five Generals, Reramos unleashed Karantular to defeat them. He used his website to trap the team. BoBoiBoy uses his elemental split to split into BoBoiBoy Thunderstorm, Ice and Cyclone and freed himself from the webs. BoBoiBoy Cyclone freed Kuputeri from Reramos's chains while Thunderstorm attacked the Spider. Karantular soon defeated Thunderstorm and Ice took over. While Ice was fighting, Kuputeri told Cyclone that the only way to defeat Reramos is to use Tempest. When Karantular defeated Ice, instead of attacking Karantular, Cyclone attacked Reramos and try to take LampBot from him. Cyclone trapped Karantular in his Cyclone to fight him but Karantular soon overpowered him. Atlast, Cyclone evolved into BoBoiBoy Tempest and defeated Karantular with one attack.
