The Protector

Description
One of the Champions that can invade the lair. To trigger his spawn, merge Undead Aliens or Guzzlers.

Defeating him will grant a Galactic Chest. Alternatively, you can feed him to the Devourer for 2.5k Food.

He is unlocked at Devourer Level 47.

''A protector of the galaxy. The Protector's health increases each time he is beat in combat.''

His initial health scale sits at 500% but can be lowered down to a minimum of 150% with the help of an experiment by The Inventor. Regardless of Weakening Experiment level, the Protector's Base Health starts at 25,000.

Trivia
The Protector's design has a slight resemblance to "Doomguy" from the DOOM video game series: His armor is colored green and the helmet has similar features to those of "Doomguy".
