Players who choose an Aggressor Character Style should do so because their character will, for the most part, be an aggressive character.
Aggressor characters are more likely to start a fight or attack an enemy first. They are often more rash and self-absorbed than other characters may be. A character who is an Aggressor in the Atomic RPG System would probably fit under the Chaotic alignment in Dungeons & Dragons.
Since Aggressor Style Characters often start fights, they are exceptionally good at Attacking. Aggressor Style Characters will have their Character Tier added to all of their Attacks.
Aggressor Characters will also tend to favor having Offensive Disciplines as opposed to Defensive Disciplines. An Offensive Discipline is focused on harming enemies rather than helping allies.
