This fearless agent of the Imperial Security Bureau works well in many situations. Her abilities are a mix of the Sith Trooper and the ARC Trooper's abilities.
She is armed with two RK-3 Blaster Pistols, one of which she can fire a Power Blast from. The Power Blast can lock onto enemy troopers and vehicles, and can correct itself midflight to hit them. Holding the fire button fires both blasters. Her elegant kicks replenish her health.
The Agent can run into and out of hotspots with Assault Training, which grants her damage reduction while sprinting and increased sprint speed.
Are there Rebel scum that are nearby your location, but they're all hiding? The Agent's Imperial Intel scans the four nearest Rebel scum, up to 10, increasing for every kill with this ability active.
Double Your Effort regenerates allies' base health, but can only be used when an ally is nearby. The effect also extends to friendly Heroes and Villains as well, and can completely heal them past their standard regen cap.

ISB stands for the Imperial Security Bureau, which was a clandestine law enforcement and intelligence agency for the Empire that employed secret agents who were skilled in combat and sometimes led and fought alongside regular Imperial troopers.
One notable ISB Agent in the Star Wars universe was Agent Kallus.
Dave Filoni when creating Agent Kallus described the ISB as similar to the FBI or the Military Police.
