Sol is the first boss of Space Invaders Infinity Gene. It first appears in stage Apoptosis.
Appearance[]
Sol is a cylindrical ship with a bullet-like appearance. It has no clear cockpit or other defining features aside from the top being slightly separated from the main body.
In comparison seen from the 3D levels, Sol spins as it descends and attacks as seen from Stage 5-1 "Organizer". Its cannon can also be seen from the underbody when the camera pans view from below in the 3D levels.
Battle[]
Sol fires large lasers whose locations are indicated by thin, dotted lines.
Sol starts from the top of the screen outside of the player's view, firing three lasers in any part of the field. The ship then descends to the battlefield, and utilizes the same attack pattern only to move where the player is at a sluggish pace.
Name[]
Sol is another word for "Sun." Its usage is likely a reference to the orbital weapon of the same name in the manga Akira.
Nagoya Attacks[]
It is possible to attain Nagoya Attacks from Sol as being very close with the ship will ensure increased points. Nagoya Attacks aren't plentiful since prolonged exposure to the lasers regardless of being close will vaporize the player and lose a life. The player must make sure they're close while also cutting along the side to avoid being caught in the laser too long.
In the Console DLC[]
Sol doesn't change much in the DLC version/bonus levels, but in some instances you will see more Sol enemies pop up. An example such as Bonus 1-5 "Point Deletion" where multiple Sol overtake in one part of the level when the emergency message kicks in.
