CN-7 Cain Voicepack

A special duty robot built by Advent, but abandoned due to his state-of-the-art AI being too empathetic towards humans. His serial number is CN-7, but he prefers to ba called Cain.
Additional notes: for unknown reason, Advent decided to give him a French accent. During the combat his speech module got damage and Cain is now calling everyone a "monsieur".

Over 500 lines
He has his own robotic voice filter
No names from Binary Domain
But bunch of French words (especially "monsieur")
WotC not required, but full support for heroes granted

While this voicepack will work for Spark, with some Xcom2 mods you can recreate Cain as "human" soldier (at least in WotC):
Augmentations to get some robotic arms, legs and head. Worthy note, this mod change "gravely wounded" mechanics a bit, but you can disable them with ini edit.
Warden Gear for the scarf.
I used one of default kevlar vests for his torso.

You might need Unrestricted Customization to mix those mods, I'm not sure.

Since a lot of people ask, to run Vanilla-made voicepacks in WotC I suggest using Alternative Mod Launcher[github.com].
