Players that choose a Protector Character Style should do so because their character will protect friends and allies first, even above themselves.
Protector Style characters will almost never attack an enemy first. They may seek out a solution without battle, but will rarely initiate it when it does happen. Protector Style characters will often be bound by honor or loyalty to their allies. Protector characters often look at a bigger picture than their own situation. When speaking in Dungeons and Dragons terms, a Protector Style character in Atomic would fit under the Lawful and Good alignment for Dungeons and Dragons.
Since Protector Characters do whatever they can to protect their allies, they have naturally good Defenses themselves. Protector Style Characters will have their Character Tier added to all of their Defenses as a Build Bonus.
Protector Style Game Mechanic Benefits
Protector Characters do not usually have a preference when it comes to having either Offensive Powers or Defensive Powers. Their Powers are often focused on helping their allies through increasing their abilities and healing them, although Protectors can easily be focused on Offense, brutally attacking enemies that dare harm their allies.
Traditional character types that would be considered to have Protector Character Styles might include knights, paladins, clerics, priests, heavy engineers, medics, and any other character that wants to be very good at character Defenses.
