Shielda

Shielda is a character in BoBoiBoy Galaxy and was one of two Power Sphere Guardians in Planet Volcania, a member of TAPOPS and the younger twin sister of Sai.

“A Fiery Fight”
Shielda debuts in this episode alongside her brother Sai as Fang's teammate in Team A. They had been ordered to stop BoBoiBoy and friends from passing the Toughness Test and reaching their objective, which was to retrieve the Power Sphera on top of the volcano. She and Sai relentlessly attack BoBoiBoy’s gang, eventually defeating all of them but BoBoiBoy. Set on fulfilling their orders, they prepare to defeat an already weakened BoBoiBoy, but are stopped by Fang. Shielda and Sai mock him for having sympathy for ‘weak’ Earthlings, provoking BoBoiBoy enough to activate his new elemental form, BoBoiBoy Fire. In the fight that followed, Sai continued fighting even as Shielda and Fang yielded. She unleashes her shield’s presumably most powerful attack on Fire, only to have Fire easily stop it and divert it back to her. Tarung saves Sai by catching the shield with his teeth, and is relieved when Tarung ends the Toughness Test. She is evacuated with the others when the volcano starts collapsing.

Upon arriving back at the TAPOPS Station, she apologize to BoBoiBoy for going too far.

“Phantom Thief Panto”
She makes a cameo in this episode as she and the other two Team A members are stationed to guard Jokertu’s cell.

“Looping Loopa”
She also makes another cameo when she is shown defending the TAPOPS Station alongside Fang and Sai from Space Pirates.

"Pirate Armada Invasion"
She cameos along side with sai waiting for BoBoiBoy and the others to arrive at sunnova station.

"Light of Hope"
She and Sai almost had a big role while teaming up with BoBoiBoy and his friends on fighting Vargoba.

"BoBoiBoy Movie 2"
She and Sai appears in the movie shown to be helping evacuate the Cendawa aliens. After the people of Planet Rimbara get into the spaceship, Shielda takes care of them while Sai pilots the spaceship to take them to safety.

Physical Appearance
Shielda is typically seen wearing a green hooded suit of armor that contains both metal and gold elements, with designs reminiscent of her brother Sai's attire that has the colour of red, yellow, green, and black. However, her outfit provides more coverage for added shielding and protection. Additionally, she wears a loincloth-style velvet fabric around her waist, which is adorned with gold edges and features a white symbol that is similar to the one displayed on her brother's belt.

She is wearing a forehead crown accessory that has a relatively simple design, with what appears to be a small yellow jasper attached to it. Both her and her twin have three dots on their cheeks which seem to be their birthmarks.

In BoBoiBoy Movie 2, she and her twin, Sai undergo a change of attire, with their new clothes featuring less armor and metal. The reason for this change is possibly due to the constant use of magnet powers by their opponent, Captain Vargoba, which affects the metal content in their clothes.

Personality
Like her brother, Shielda is portrayed as a serious and efficient, and mature individual, especially when taking her missions seriously. She and her brother had relentlessly attacked BoBoiBoy and his friends and didn't hesitate to take action. However, Shielda has a more thoughtful and patient nature than her brother, as demonstrated when she was willing to back away from fighting BoBoiBoy Fire, realizing that such action could worsen the situation.

Somehow, both twins seem like calm individuals.

Skills
Although less mobile than her brother, Shielda is shown to be incredibly strong, able to hold her shield against strong attacks from Yaya and even able to charge BoBoiBoy Fire, one of BoBoiBoy's most violent forms.

Abilities
Her main weapon is a shield with an eagle pattern on its surface. She uses it with her left hand. The shield is mainly used defensively, in contrast to her brother's more offensive tactics.

It has an ability to reflect any attack and objects, including sounds and insults. It can also be used for attack when it hits the ground, which is shown when she hits the shield on the ground, sending a line of rocks towards Yaya.
