The Guardian Legend/Enemies

Defense System
The first boss encountered in the game, it is found at the end of the initial flying scene. Consisting of both large and small turrets across the screen, it is the only instance of this boss in the game (no colour variants).

Fleepa
A large fish-like boss, it mainly travels vertically up and down the screen while attempting to maintain the same horizontal position as the Guardian. It will occasionally produce smaller fish from its mouth which seek out the Guardian. Comes in two variants, blue and red.

Optomon
A large fuzzy eyeball, the Optomon shoots standard bullets at the Guardian’s position as it travels horizontally across the screen. More importantly, Optomon regularly spawns/drops long seaweed-like strands that slowly descend on screen which cause devastating damage should the Guardian touch them. When faced with a choice between touching a bullet or seaweed, always take the bullet.

Crawdaddy
A large crayfish which, similar to Fleepa, travels vertically and releases smaller projectiles. If the Guardian changes horizontal positioning, Crawdaddy will attempt to match position but will gain speed and bounce off the sides of the screen like a pinball, becoming more difficult to target. Recommended strategy is to stay directly underneath Crawdaddy without moving and continuously shoot Fireball.

Bombarder
Bombarders will appear randomly on the screen, launch a barrage of heat-seeking missiles in a full circle, and then disappear from the screen before reappearing in a different location. Use of the Saber Laser is the recommended tactic. Appears in blue (“silver”) and red variants.

Clawbot
Clawbot is a boss with two phases. During phase one he will fire homing missiles from the side and occasionally open his 'claws' to fire a large laser. During phase two, he will lose his claws, which slowly descend towards the bottom of the screen, and Clawbot will fire the laser continuously. Comes in blue ("silver"), green, and red variants.

It
The final boss of the game.
