Class-D Guardians

The Class-D Gaurdians are a boss, and the 6th boss overall of Environmental Station Alpha. The player fights them shortly after reactivating the main generator, which will cause any robots, including the Guardians you fight, to awaken and attack you. Each Guardian shares about a third of their whole health bar.

Physical Appearance
The Class-D Guardians consist of a group of three defense robots colored yellow, green, and red. They look like the Class C Guardian, but smaller.

Attacks
Each Guardian has their own attack, which will be different depending on their color. The bosses will no longer be able to attack if they are damaged enough.

The Yellow Guardian attacks by rapidly firing yellow projectiles aimed directly at the player, they should constantly be on the move in order to not get hit.

The Red Guardian attacks by dashing. It will track the player for a few seconds before locking on to the area to dash into. Once it hits a solid surface, will create an explosion in a small area.

The Green Guardian will attack by summoning green projectiles that rise from the background and fall into the foreground, where upon hitting the surface, will create a green wave-like explosion that's almost similar to the Scrapping Unit's charged bomb attack.
