BoBoiBoy Water (Malay: BoBoiBoy Air) is one of BoBoiBoy's new elemental forms. He made first appearance in Season 3, Episode 18. His second evolution form is BoBoiBoy Ice. He will return in BoBoiBoy Galaxy.
BoBoiBoy Water is shown wearing long-sleeved black shirt with cyan blue vest. He also wear the black trousers and a pair of black, icy cyan blue, and white shoes. His hat is also in dinosaur-style, with the icy blue colour worn directed forth.
When BoBoiBoy first turned into BoBoiBoy Water, he was chubby and moved sluggishly. His sluggish form caused his powers to be rendered as useless because the usability of his powers depends on an active-moving body. Later in Season 3, Episode 19 after he went through weight loss training created by Papa Zola, he changed significantly in spite of size and activeness for the better.
BoBoiBoy Water is the most relaxed and laid-back form. He dislikes engaging in combat and much rather attempt to subdue the opponents via a discussion in hopes of stopping them from fighting. Water is shown the weakest element and not to be easily entertained and gets bored easily when doing things he doesn't want to do. Despite being just as strong as the other forms, his laziness gets in the way and often times, Water just doesn't use his full potential. However, he outgrows this trait in the fight against BoBoiBot, where Papa Zola finally convinces him to get a little serious once in a while
After this development, Water is much more willing to fight, but still showcases his laziness by sitting on his water bubble.
