Description
Allan Adams is an engineer focused on Plavsky particle technology, initially part of PPSE company's Gundam Works division, which monopolizes the Plavsky particle generation system. His expertise ranks him among the world's top Gunpla builders. During this time, he frequently served as the primary support technician for Meijin Kawaguchi the Third (Tatsuya Yuuki), indicating a professional partnership and underlying personal concern, despite his typically passive nature and reluctance to involve himself in others' matters.

Following events disrupting the Plavsky particle system, he shifted into education, becoming an instructor and head coach at the private Gunpla Academy. This vocational institution for Gunpla builders formally incorporated the previous academy structure. In this role, he mentors the school's competitive team, Celestial Sphere, which includes his nephew Wilfrid Kijima and niece Shia Kijima. His leadership centers on providing technical guidance and strategic development for tournament competition.

His involvement with experimental battle systems continued later. During a visit to Yajima Trading's research and development center alongside Meijin Kawaguchi the Third, he participated in testing an advanced update to the Gunpla Battle operating system. This update introduced an automatic control mode using artificial intelligence modeled on pilots from various Gundam universes, designed to allow participation without piloting skills. For this demonstration battle, he deployed a customized Reversible Gundam, based on the Reborns Gundam, and selected an AI modeled after Ribbons Almark to pilot it against Meijin's Ballistic Zaku piloted by a Char Aznable AI.

Within this battle, he demonstrated technical ingenuity and a subtle sense of humor by activating a concealed function that switched the Reversible Gundam's controlling AI mid-combat, unexpectedly changing it from Ribbons Almark to Amuro Ray. This tactical surprise resulted in the battle ending in a draw. The action highlighted his deep integration into developing new battle technologies and his understanding of their potential for facilitating diverse matchups. His ongoing collaboration with Meijin Kawaguchi the Third remained evident through these joint technical endeavors.
