BoBoiBoy Ice

BoBoiBoy Ice, also known as BoBoiBoy Ais, is the evolved version of BoBoiBoy Water. He made his debut in BoBoiBoy: The Movie.

BoBoiBoy: The Movie
BoBoiBoy first evolves Water into Ice after witnessing Ochobot's death at the hands of Bora Ra. With this newfound power, BoBoiBoy uses Ice alongside the other evolved elements to defeat Bora Ra.

BoBoiBoy Movie 2
BoBoiBoy calls out Ice during a routine Power Sphere retrieval mission. In order to save himself and Gopal from falling to their doom, BoBoiBoy transforms into Ice to freeze out a path for him and Gopal to slide down on. They were disrupted by the beast, but Ice manages to save both himself and Gopal.

Ice becomes one of the three only elements to avoid being absorbed by Retak'ka. When BoBoiBoy and his few friends managed to escape, they crash landed on a planet. BoBoiBoy calls out Ice to freeze the acidic swamp water to allow everyone to escape.

BoBoiBoy Ice is called out when Hang Kasa begins to train them, teaching Ice how to fire his ice bow properly, as he was using all power but had no accuracy. He can later be seen training alongside the other elements when training with Hang Kasa.

After witnessing Hang Kasa's death, enraged, BoBoiBoy calls out his two remaining forms at the time, Ice and Blaze, and fuses into FrostFire to fight back against Retak'ka. He later summons Ice alongside Quake, to transform into Glacier.

BoBoiBoy Galaxy (Season 2)
In Back in Action!, he first appears in an Elemental Split consisting of himself, Blaze, and Thorn after Adu Du kidnaps Ochobot and tried to run away with him. He and Thorn work together to trap the squarehead, preventing him from escaping. Ice is also the one who tells Blaze to put away his Maximum Fireball after Adu Du and Probe have already managed to teleport.

In A Mystery in the Canyons, BoBoiBoy transforms into Ice to stop Qually after he stole the Blue Flame. He gives Gopal ice skates using his powers to allow him to give chase. The two also perform a combo attack to try to slow Qually down. However, one of the Ice Arrows narrowly misses the flower. Qually blinds the duo, but Ice manages to block the attack using his shield. Just as Qually is about to take the Blue Flame, the fox whom BoBoiBoy rescued earlier attacks him, allowing Gopal and Ice to trap him.

In The Ultimate Recipe!, Ice is summoned in a Penta Split consisting of himself, Blaze, Thorn, Thunderstorm, and Quake during the cook-off against Qually. He nearly places the entire Crystal Salt in a pan. While trying to extinguish the flames Blaze conjured as even the pan burned, Ice unintentionally ends up freezing the pan. Toward the end of the cook-off, he and Blaze are told by Quake to fuse into FrostFire, who uses Frozen Heat Explosion and prepare and serve the Tom Yum.

In The Battle for Windara!, Ice is again summoned in a split alongside Cyclone and Thunderstorm to engage Karantular and defeat the spider. However, he is knocked out by the spider while trying to defend himself from its acid spray.

Appearance
BoBoiBoy Ice has light blue eyes. He wears a gray long shirt and a gray jacket with light blue zig-zag patterns. The vest has the hoodie that covered his head. He also wears dark blue trousers with same zig-zag patterns in his jacket and blue and white sneakers. He wears a dark blue hat that covered his hair with the same zig-zag patterns, an emblem of his power, and the three imitation blue thorns.

In BoBoiBoy Movie 2, most of BoBoiBoy Ice's features are similar to that his previous incarnation, but now his coat is longer and the hood is lined with fur. There's a detail where his right hand is made out of ice.

Personality
BoBoiBoy Ice has a similar personality to Water, being a calm and relaxed, albeit slightly lazy individual. Though Ice does not show much of the lazy characteristics and can be seen focusing on the task at hand.
