Sai

Sai is one of the members of TAPOPS. He was one of the two Power Sphere Guardians in Volcania.

Appearance
Sai wears traditional type clothing, akin something similar to a ninja. He wears his shield weapon in a form of an Asian conical hat.

Biography
Sai first appears in BoBoiBoy Galaxy in Episode 11 alongside his sister Shielda, as Fang's teammates in Team A, and assigned to stop BoBoiBoy and friends from reaching their objective, which was to retrieve the Power Sphere. He and Shielda relentlessly attacked BoBoiBoy and his friends, as well as provoking BoBoiBoy enough to activate his new elemental form, Fire. Despite trying to keep up with his attacks, Sai was eventually overpowered. He was later evacuated when the volcano started collapsing.

Later, Sai appears briefly in Episode 12, stationed to guard Jokertu from escaping prison.

Personality
Sai, like his sister, is shown to be fairly serious and efficient people. They are devoted to their orders that they are given and follow through it to the fullest. Sai does seem to get a bit heated in combat, showing his unwillingness to be defeated, despite obviously being overpowered by BoBoiBoy Fire.

Skills
In addition to being adept with his weapon, Sai is shown to be very lithe and flexible. He can jump from high places and can easily dodge attacks.

Abilities
His main weapon is a shield that he wears like an Asian conical hat, and he wears it on top of his head. Using his finger, he can control his shield's movements and directions. When he throws it, it can hit and cut any targets, and fly back to him like a boomerang. He can command his shield to move in zig zag movements to make it more difficult for his opponents to predict its exact movements.

When it hits the ground, it creates an explosion that can knock opponents off. He also uses it for defense, such as cutting rocks flying towards him or to shield off attacks. Surprisingly, the shield is unaffected by Ying's Time Manipulation when it enters the slow-mo field created by Ying.

Maximum Spin seems to be Sai's most powerful skill as he uses it in the last resort in an attempt to defeat BoBoiBoy Fire. However, even with the shield spinning in maximum speed, it can still be caught and stop by BoBoiBoy Fire's hand and later, after being powered up by Fire and Tarung's teeth.

Trivia

 * His name "Sai" is the last three letters from the word "Perisai", which means "shield" in Malay, which is also his weapon.
 * Additionally, the name 'Sai' can also originate from the Japanese name '哉' (Sai) which means 'paint', though the Malay meaning makes much more sense.
