Name: Ultra Girl Vesperia Alias: Anti-Ultra Girl Combat Weapon Height: 52m Weight: 46,000t Flight Speed: Mach 10 A combat weapon created by the invading aliens, the Zaikro, who used a supercomputer to thoroughly analyze Ultra Girl's combat data in order to destroy humanity's hope and trust in her. Her appearance intentionally mimics the real Ultra Girl. While Ultra Girl is the hope of Earth and a symbol of light, Vesperia's body is colored black and gold—the polar opposites of red and silver—to represent Earth's despair and shadow. She has long black hair and purple eyes. The Color Timer on her chest is gold instead of the usual blue. From a distance, anyone would think she is the real thing. However, a sense of wrongness lingers up close. Her body lacks the warmth of life. The Color Timer on her chest is not a heart, but a massive power reactor. Her interior is packed with countless mechanical parts and processing units. And above all, she does not smile. Being a robot, she has almost no personality, but she possesses a minimal pseudo-personality for dramatic effect. She is extremely calm and lacks emotion. She perceives humans as an audience and makes declarations during battle specifically for people to hear. Vesperia was built specifically for combat against Ultra Girl, giving her combat capabilities incomparable to normal monsters. She possesses power and defense far surpassing an average Ultra Girl, while remaining mechanical and precise. Furthermore, her built-in self-evolution function allows her to analyze combat experience to grow even stronger, making previously effective techniques useless. She also frequently uses psychological attacks that exploit the fact that she is a fake. She is usually stored inside the frontline base of the Zaikro's Earth invasion plan and deploys upon receiving orders. Main Unique Abilities: Vesperia Shot: A technique that fires powerful light bullets from her clenched fists. Vesperia Barrier: A circular barrier that blocks attacks. Defense Shield: A shield equipped on the Color Timer. It automatically appears to protect the Color Timer if it is targeted. Vesperia Blade: Energy blades deployed from both arms. Zero Field: A special barrier that absorbs surrounding light energy. It gradually drains Ultra Girl's activity energy, forcing a long-term battle. Mind Control Beam: A brainwashing beam fired from both eyes that controls the brainwaves of any living creature. Desperate Ray: A lethal red-black beam fired from the entire right arm by crossing the arms in a cross shape.
