Ultra

An ultra is the most superior type of enemy. They have increased health, shields (if any), and damage output and are distinguished by a yellow health bar, a special name, and a skull icon instead of a level number.

Ultras cannot be debuffed with blinding or suppression from Flashbang and Suppressor Grenades, though they can still be inflicted with burning or damage over time. Ultras often have a unique or slightly different physical frame and have a short cooldown on when they can perform their melee attacks.
