Void Ripper
Overview
Void Ripper is a NPC ally you can find during the mission Break prisoners out of the Zig from Operative Wellman (CoV, levels 15 - 20). He is one of the prisoners you must help to break free out of the Zig. He will be in a cell guarded by a Private Security Captain when you find him first, and must be freed so he can help you. Once free, he will follow you and will attack any Longbow soldier or prison guard in his aggro range. Longbow will send at least three waves of attackers against you once you free him.
During my mission, Void Ripper had Pet class and hit points. He used a mix of Dark Blast and Dark Melee attacks and I never saw him activate any secondary defensive powers.
Remember that at least one of the prisoners must reach the helicopter outside, so he's one of the possible mission objectives, and must survive.
Quotes
Void Ripper seems pretty friendly, for a villain:
Once free: Alright. Let's bust outta this joint!
At the mission exit: Sweet freedom!
