OVA
Description
General Geisel is the primary antagonist of the story. He is a military commander leading a rogue faction of the planetary forces on the colony world of Ietta. His position grants him authority over significant military resources, including an underwater base and a fleet of warships. His most notable act at the beginning of the narrative is the murder of the scientist Nalderof Aldo Mordish, the father of the young heroine Elysse, an act carried out in front of her after she escapes in an escape pod.

In terms of personality, Geisel is portrayed as a ruthless and power-hungry individual driven by a desire for conquest. He is depicted as a menacing, stereotypical villain whose primary motivation is to seize control of a gravity repulsor or gravity generator, a device essential to keeping the planet stable, and convert it into a superweapon. The narrative does not provide deeper insight into his personal history, his ultimate goals for the weapon beyond simple domination, or his standing within the larger military hierarchy.

Geisel's role in the story is to be the direct obstacle for the protagonists, the crew of the Cha-Cha Maru led by Captain Tita Mu Koshigaya. He is the force hunting Elysse, who holds the genetic key, the last twelve digits of her DNA sequence decoded using a specific method, needed to activate the weapon her father sabotaged. His pursuit of her drives the plot forward, culminating in a direct confrontation where the protagonists launch an assault on his base to stop his plan. Due to the short length of the original video animation, his character receives minimal development and is largely defined by his antagonistic function rather than any internal change or complexity.

Geisel is noted for having a distinctive and imposing character design, which effectively conveys his physical threat. His notable abilities are those of a typical action genre villain; he is a formidable combatant. In one key scene, he demonstrates his physical strength and brutality by easily lifting Tita with one hand and shooting her at close range, which severely wounds her and showcases his menace. Beyond his personal fighting prowess, his primary power lies in his command of a military force, which he uses to relentlessly pursue the protagonists.
