At Thug rank after initially buying the power, the Arc Lightning allows Cole to release a continuous stream of lightning towards anything that is aimed at until Cole stops or run out of Battery Cores to use. The Outlaw rank upgrade allows Cole to branch out the Arc Lightning to an unlimited amount of targets so long as they are close enough in the direction that Cole is aiming. It also increases the damage received by enemies that are hit by the Arc Lightning. The Infamous rank upgrade causes weaker enemies to trigger an electrical explosion upon death.
- Arc Lightning is one of two powers in Infamous that only becomes available through the completion of side missions, the other being Overload Burst.
- Cole's use of Arc Lightning is similar to the use of electricity by other popular icons with electrokinesis, such the Sith of Star Wars and DC characters Static Shock and Black Adam.
