Security Mainframe
From City of Heroes: Rebirth - Wiki
The security mainframe
Overview
Security Mainframe appears on the mission Steal Wretch's Medical Records - without witnesses from Seer Marino. There is just one in the mission and will have some guards around. It can't move, nor has any attacks, nor any special abilities or effects. During my mission (Villanous, solo) it had slightly more hit points than a Lieutenant of the same level, which probably means it was a watered-down Boss class object. It is destructable, and any hero or NPC caught in its blast will suffer some damage:
Small Explosion Area of Effect, Moderate Damage (Lethal/Fire), Foe Knockback. This object erupts into a small explosion if destroyed.
Description
The mainframe computer must be destroyed.
