Aiga Akaba

is the main protagonist of the anime and manga series, Beyblade Burst Super Z. After witnessing the strength of Valt Aoi's new bey, Aiga decided to create his own bey, Z Achilles 11 Xtend and become a Blader. Afterwards, he moves to the big city, where he sets out on a journey to become strong enough in order to defeat Valt someday.

Appearance
Aiga looks similar to Valt, except he has lighter skin, turquoise eyes, wears red clothing and his hair and eyebrows are maroon. He has a red letter "A" tattooed on his left cheek, and several bandage strips on his face: a horizontal one on his right cheek, two horizontal ones placed vertically on the right temple, and a horizontal one over an "X" shaped bandage underneath it on the left temple.

Aiga's attire consists of a white shirt, jet black shorts with blue-buckled suspenders, a short-sleeved burgundy letterman's jacket with a black-striped white collar, tomato sleeves, border and pocket lining, and burgundy sneakers with a tomato border, white laces, white toe caps and a white circle with an upside-down dark-blue "A" on each inner heel. His jacket has a light-cyan circle with an upside-down dark-blue "A" on the back and three yellow buttons on the front: one on the right side with a dark-blue Beyblade symbole, and two on the left, the upper one an upside-down dark-blue "A", and the bottom a dark-blue star. After his first battle with Valt, Aiga began wearing a dark-blue hand brace on his left hand and wrist.

When he's about perform his bey's signature move, his hair turns crimson and breaks free from the blue rubberband holding it upright.

Personality
Aiga is very hot headed and cannot stand losing as he was infuriated after is defeat at the hands of Valt Aoi. However, similar to Valt, he has been thoughtful of his strategies and wins battles because of them. He also acts like a big-shot at times, such as when he brags about his victories and so-called "invincibility".

Having lived on a farm for most of his life, Aiga loves animals. He also elects to sleep in a tent in Beigoma Academy's petting zoo instead of the school's dormitories so he can be closer to the animals.

Aiga acts like Valt in many ways. They are both passionate about blading, and can easily make friends. (Valt made friends with Rantaro Kiyama; Aiga made friends with Rantaro's brother, Ranjiro)
