BoBoiBoy Thunderstorm

BoBoiBoy Thunderstorm is the evolved elemental form of BoBoiBoy Lightning after being tortured by Adu Du and Probe. He is the first elemental form to evolve in the series. Thunderstorm is slated to appear in BoBoiBoy Galaxy.

Original Series
Thunderstorm first appears when Lightning is kidnapped by Adu Du and Probe. He was then tortured by them via exploding balloons, revealing that BoBoiBoy had globophobia.

Out of stress and fear, Lightning inadvertently transformed into Thunderstorm, but in the process, he completely forgets himself, a possible side effect from being split up for too long. Realizing that Thunderstorm had completely forgotten who he was and his sense of self, Adu Du tricks Thunderstorm into think that they were his friends.

He later attacks his true friends alongside Adu Du, even attacking his other two elemental forms, Wind and Earth. Thunderstorm absolute emancipated them, but as he is about to deal with the finishing blows, Probe triggers his memory after he says his catchphrase ( Yeah, awsome ). As a result, Thunderstorm regains his memory and turns on Adu Du.

Galaxy
Thunderstorm is slated to appear in Galaxy.

Appearance
His bodily appearance is the same as the other forms of BoBoiBoy's elemental personas, with having the same physique and cropped black hair. But unlike the others, BoBoiBoy Thunderstorm possesses scarlet eyes and is clad in mostly red and black. He wears his signature cap in a common style where the bill is at the front. The cap is fully black in color minus the three white 'horns' decorating the top, neon red lining adorning the rims of the bill, and his signature red lightning bolt insignia rests on the center of the cap. His vest that he zips halfway up is black as well, with dark red linings on the hoodie, neon red jagged lightning-like patterns on either sides on the front. He wears a red shirt underneath the vest and its sleeves are 3/4 long with black cuffs. Fully black pants and shoes that are a mix of red and black to complete his attire.

Personality
Due to being the evolved form of Lightning, technically a personification of BoBoiBoy's anger, Thunder is just as or even more aggressive than Lightning is. He is shown to be ruthless and almost wrathful in combat and did not hesitate to hurt his friends when under the influence of Adu Du. However, he is still BoBoiBoy at heart and still retains some semblance of his original self.
