Name: Akio Sanada

Hero Name: Aether

Quirk: Quirkless (Currently), Aetherforce (Formerly, Dormant)

About the Aetherforce:

Aetherforce is a rare, high-output quirk that allows the user to generate, shape, and release electro-spiritual energy—a unique hybrid of physical electricity and life-force “aether.” This energy can be used for mobility, striking power, binding, and long-range attacks.

The quirk enhances the user’s muscular structure, reflexes, and durability, making them far stronger than normal humans even before releasing any energy.

Aetherforce is known for its balance of speed, technique, and precision, making Akio both a close-quarters fighter and a mid-range specialist.

Akio Sanada's Suits/Costumes throughout his story from left to right:

U.A Years

Alpha (Season 1)- This was Akio's homemade suit designed and crafted by him and his dad. Features a bulky Light Blue jumpsuit with light gray gloves, Black shoes, a visor with a light blue lens with a light gray frame and a dark gray belt.

Beta (Season 2-3) - After having the results of costume Alpha, a slightly modified version was created by U.A.'s support course, Featuring celadon blue color, The visor's frames having the same color. The suit's visor would be given a heads-up display by David and Melissa Shield in Two Heroes for tactical.

Gamma (Season 3-4)- Following the Provisional License Exam and an internship with Sir Nighteye's agency with his best buddy, Izuku Midoriya, the support company Can't Take Heroics seriously (CTS) gave the costume minor changes. like his closest friend, Deku (Izuku Midoriya, he was also given iron soles for the same purpose of kick attacks. The suit's gloves were longer, reaching fro. the hands to the forearms. Each hand has a port placed where all 4 knuckles are (2 ports for each hand, and per 2 knuckles) that serves as emitters for Aetherwhip.

Delta (Season 5)- This was a minor modification of the Gamma costume, primarily incorporating the silver armored gauntlets (in the same color as the gloves) which serves as regulators to prevent from any future overheat and strain on the arms and shoulders, as a permanent fixture and featuring slight aesthetic changes such as a silver mouth guard with Celadon lines running though it.

World Heroes' Mission Stealth Suit (Movie Only): For the World Heroes' Mission movie, Akio received a special stealth suit from the World Heroes Association (WHA) for their global mission. It was black with Light Blue accents and WHA shoulder plates.

Epsilon (Season 6)- After Izuku left UA to protect his friends and went rogue, Akio left UA aswell, but to bring back his best buddy. This suit is a heavily damaged and grimy version of his Gamma/Delta costume, to show how long he had been finding Izuku while traversing through the ruined cities of Japan and fighting off numerous villains. The armored gauntlets were damaged, causing Akio to be careful when using Rail Burst. Light blue scarf his father he wore during his prime.

Zeta (Season 7)- This shares design elements with Izuku's Zeta costume. Also being a cleaned version of the Epsilon suit, featuring a full array of support gear: the iron soles, his very own mid gauntlets, and his father's scarf as a permament fixture. This his suit had a more vibrant blue to the suit and was given bouble barrel wrist mounted cannons for "Going On the Offensive". The cannons could be configured into bombs.

Eta- A kitbash of previous suits. Given to him after he losing his quirk to defeat All For One, causing the quirk to lay dormant again and Akio to be quirkless. The suit's support gear was designed to mimic the abilities of the Aetherforce. It features various functions, including retractable Aetherwhip-like electric cables, a flight pack for as the name suggests, Rail Burst repulsors that could be set to beams or blasts (Lethal or not). The gear also had a retractable mouth guard.

Pro Hero Costumes:

Theta- What Costume Eta would eventually become 8 years later, featured with the same nanotech used in All Might and Deku's powered suits. Not only was this high-tech, armored suit able to mimic all of the Aetherforce's abilities, It could also mimic the abilities of his 1A comrades. There were additional weapons such as 2 red laser beams (1 per each wrist) which were limited. The retractable mouth guard had evolved into a visor turned helmet during combat. However, it wasnt invincible (No pun intended). During a mission, The suit suffered severe damages from powerful attacks and bullets that the suit couldnt handle.

Omega- The successor to Eta, this suit was just a slight change in asthetic. However this was more advanced than All Might and Deku's due to it now being more durable than Theta. Visor turned helmet was now a permament fixture, but the helmet's antenna's were elongated, somewhat giving it an optimus prime like look. Many upgrades such as enhanced micro lasers, stronger output for the Rail Burst repulsors, and additional weaponry such as two large arm cannons that are only used for last resorts (Cannons are like the repulsor cannons of MK50 in Infinity war)
