Arsonist's a robotic figure with an undisclosed origin. Their gender is none. One of Arsonist's abilities permits itself to construct their 'Energy' meter, requiring them to cause 300 damage to opponents in order to fill it completely. When all the points are filled, they will be granted an Invulnerability boost and critical boost of 12 seconds. The cooldown of the Energy meter (18 seconds) can be reduced by picking up ammo packs or getting kills.
