Akumantle serves as an operative within the antagonistic Devilvader organization, opposing the B-DaCop protagonists. He possesses a distinctive mustache. Akumantle initially commands a unique scorpion-themed personal mecha, setting him apart among Devilvader's early forces; this mecha functions as his primary combat unit. He operates as part of a recurring trio alongside fellow Devilvader agents Docdandy and Gestler, with Gestler identified as the group's intellectual component. Akumantle engages in multiple mission-based confrontations against the B-DaCop team. By Episode 20, during their collaborative efforts, both Docdandy and Gestler acquire their own mecha units. Akumantle remains active within Devilvader's command structure throughout these developments, serving under King Vader's leadership while executing the organization's assigned missions.
