Super Hero Taisen Alpha is part of the Super Hero Taisen franchise, and was published for the PlayStation and Dreamcast, by Banpresto in 2000. Super Hero Taisen Alpha is the first game of the Alpha series, which spans over 5 years and is set 2 centuries before the Classic era games.
- Masato Inoue - Daughter of the investor of the Alpha Wing armor.
- Kusuha Mizuha - A nurse-in-training turned pilot of the Grungust Type-2 and RyuKoOh, her boyfriend's the easily flustered disciple of the Jigen-ryuu school of swordsmanship Bullet. Kusuha's usually a sweet, everyday girl who dislikes fighting, but is infamous for one thing: her health drink knocking out the toughest of men. Only a few men and anything cyborg, robot or android are unaffected, but it's usually a major source of terror from her otherwise shy appearance.
- Brooklyn "Bullet" Luckfield - Kusuha's boyfriend, Bullet is a promising Psychodriver and pilot for the Earth Federation Army, and the default partner option for her. Pilot of the Huckebein MK II and KoRyuOh.
- Ryoto Hikawa - Son in a family that owns a karate dojo and is quite skilled in the art. Pilot of the Huckebein MK III.
- Rio Mei Long - A bridge operator on the Hagane. Her father Yuan Mei Long works for Mao Industries as its director. After pleading with Major Ingram for a shot on the piloting roster, she is welcomed as a fresh rookie to help the battleship on its mission to defeat the Aerogaters. Pilot of the AM Gunner.
- Tasuku Shinguji - A mechanic aboard the Hiryu Custom, Tasuku was unable to pass the "Personal Trooper" pilot physicals for a variety of reasons (one of which implies he's a "wet noodle"). An optimistic person, Tasuku loves to have fun and always tries to test his fate out on the battlefield. Though he has quick reflexes, his attitude can make him occasionally tone deaf, but this is offest with him being skillful at juggling enemies around.
- Leona Garstein - 18 year-old Leona is from a branch family of the Branstein clan, making her Elzam and Raidiese's cousin. Calm, prideful, and strong-natured, Leona graduates with top scores in her piloting classes and is employed by the "United Colony Corps" as part of the "Troye Unit", an elite, all-woman aerospace "Armored Module" squadron.
- Yuuki "Yuu" Jaggar - Soilder in Army.
- Ricarla "Carla" Borgnine - With a prior dream of becoming a professional dancer, it is cut short when the Aerogators attack San Diego, losing her family in the assault. Presumably, she is rescued by Yuuki, although he vehemently denies he ever did such a thing. Still, this incentive is enough that she follows him and joins the Neo Mao Army soon afterwards. Unlike Yuuki, Carla's more jovial and kind, often addressing him affectionately as "Yuu". This comes to a head when given a choice to leave the military post-Operation Plantagenet, she makes the decision to stay, despite his insistence.
