Butterfly is a boss from Space Invaders Infinity Gene that appears in Stage 4-5 "Loss of Function."
Appearance[]
It resembles a massive capsule-shaped ship with wing-like extensions comprised of many parts.
Behavior[]
Butterfly is comprised of four different stages of development. Unlike the real butterfly metamorphosis process, Butterfly attains wings in the later attack development pattern when the player destroys more of Butterfly's attacks. Butterfly stands out in the first phase as its own form as a chrysalis while firing homing lasers from its two noticeable humps on its edges at the player from a sluggish speed. Butterfly will follow the player's movement horizontally (left or right) at a slow pace while also keeping its altitude by moving up and down. When one of its forms is taken down, Butterfly will reemerge and come back with bigger wings and will attain more firepower pieces. Its last stage changes in geometric shape and it is the most powerful.
Name[]
It is named for its wing-liked shape.
In the DLC Stages[]
Butterfly's attacks become intensified whilst in the DLC levels. Its homing lasers will become more persistent while its geometrical firepower is also intensified.
