Shining Firefly

Shining Firefly, known as Shining Hotarunicus[2] (シャイニング・ホタルニクス Shainingu Hotarunikusu) in Japan, also known as Izzy Glow[3] is a character from the Mega Man X series. Shining Firefly was a reclusive firefly-based Reploid Doctor of Engineering and the world's leading researcher in laser technology.

Firefly rarely allowed any of his work to see the light of day, out of fear that they would be used to create weapons. One of his creations, the Laser Device, was one of the necessary parts needed for the Enigma cannon. But, due to the large scale virus outbreak he was already infected by the time the Maverick Hunters arrived at his lab near the Kuril Islands. While still in his right mind, he asked the Hunters to put him down before he becomes a Maverick.
