Alside is a character from the anime Beet the Vandel Buster Excellion. He is identified as a male adult character. In terms of appearance, Alside is depicted wearing a helmet, a scarf, a cape, and pants, and he is known to use a gun. He is a member of the Zenon Warriors, a group of powerful Busters. Within this group, he is recognized for his silent presence and his ability to make accurate shots.

Information regarding Alside's background, personality, motivations, and specific role in the story is not detailed in the available information. His primary known contribution to the narrative is through his signature Saiga, the Cyclone Gunner, which he eventually passes down to the protagonist, Beet. The Cyclone Gunner is materialized by the Divine Power of Wind, granting it incredible speed and immense damage potential. Its bullets can create enormous plumes of smoke upon impact, and the blade attached below the muzzle makes it effective for close combat as well.

Alside was proficient enough with the Cyclone Gunner to fire many bullets in succession without needing to reload. This ability was not solely due to a difference in Tenryoku, or divine power, between him and Beet. Instead, it was revealed that the Cyclone Gunner itself breathes air, and the user must synchronize their own breathing with the gun to fire an unlimited number of shots. Alside had mastered this technique, which is why he could fire consecutively while Beet could only manage one shot at first. The Cyclone Gunner also possesses a secondary, sniper-like form where it can fire a focused, powerful beam to accurately hit distant enemies. There is no available information on Alside's other notable abilities, his key relationships with other characters, or his personal development throughout the series.
