Hang Kasa

Overview
Hang Kasa, or known as Tok Kasa by BobBoiBoy in BoBoiBoy Movie 2, is the ruler of the 7 elementals. He holds the power of the tier-3 Crystal elemental, after Ice and Quake as he said.

History
As he mentioned in BoBoiBoy Movie 2, he and Retak'ka were best friends when they were kids. After they each found GammaBot and CrystalBot (Retak'ka taking GammaBot and Hang Kasa taking CrystalBot), Retak'ka became greedy and turned to villainy. * During a flashback scene in BoBoiBoy Movie 2, Retak'ka was seen fighting Hang Kasa with his CrystalBot suit somewhere in the galaxy. That fight took place 100 years ago, where Retak'ka was frozen using the Crystal Element from Hang Kasa. Hang Kasa then used Ochobot to absorb all the powers from Retak'ka and stored it in Ochobot (which leads to Ochobot giving BoBoiBoy his powers.) * Hang Kasa is called Tok Kasa by BoBoiBoy as he is currently old when BoBoiBoy finds him.
