Alpha Jumbosaur

Alpha Jumbosaur is the largest Plantosaur in Planet Kadruax. It debuted in ''The Merging of Two Powers!.

The Merging of Two Powers!
As Adu Du forcibly planted his supposed Oakuat seed in PlanterBot, it muted in the largest ever Plantosaur. With PlanterBot still attached to it, it became invincible as it regrew itself quite quickly. BoBoiBoy fuses into BoBoiBoy Sori and defeated it.

Trivia

 * Like the name Plantosaur, Gopal also named it as he named Plantosaurs, in it case, probably after it's grand appearance.
