Powers: Siena Blaze has the power to fire deadly force blasts of electromagnetic energy. When she fires these blasts, she literally rips apart large sections of the Earth's magnetic field, and causes localized ecological disasters. Siena does not seem to care that using her blasts could destroy the ecosystems of the entire planet. She also can manipulate magnetic fields to inhibit other mutants from teleporting. She can surround herself with an aura of magnetic energy with equal polarity to the Earth's geomagnetic field, causing the Earth to repel her upwards, and enabling her to fly via magnetic levitation. She can also teleport vast distances by turning herself into magnetic energy, and turning back at a desired location.
Bio: Siena Blaze originally started out as a member of the thrillseeking Upstarts, a group of mutants who hunted other mutants for sport. She participated in several confrontations with members of the X-Men, such as Nightcrawler and Marvel Girl and an incident in Antartica where she battled Cyclops, Professor Xaiver and Storm. Later she was transported to the Ultraverse along with Juggernaut and Reaper, where she was a member of the heroic Exiles (not to be confused with the current team of reality hopping heroes). Surprisingly, Siena adapted to the role of hero quite well. She felt a strong attraction to team leader Warstrike. Eventually she, along with Juggernaut and Reaper, were returned to the Marvel Universe. Afterwards Siena vanished from sight for years, until she met her death at the Weapon X Neverland concentration camp.
