A collection of characters from the Internet and converted to Oni. They include Faith from Mirror's Edge, Kitana from Mortal Kombat, anime schoolgirl, cyborg and ninja.
Faith and Kitana have high polygon counts so you will get the sorting buffer overflow message. Kitana and the ninja has issues with their body parts not being positioned correctly, so some animations look awkward.

A group of mercenaries based on regular Oni characters, they use the same moves as their counterparts.

Adds a custom character, Naomi.

Features:
Custom animations made by Scarlett (back-forward kick, taunts, idle1, forward kick, forward throws, powerup).
Custom moveset.
Custom chenille and contrail.
Able to link combos with another combo, throws, super moves.
She also uses some moves from other custom characters such as Sarai and Hanako.

Changes to v1.2:
New kick throw from behind added.

Adds Combustion Man from Avatar, The Legend of Aang. He has only 3 moves: Punch (for a really powerful fire rocket launcher which causes an explosion upon impact), Kick (earthquaker stomp for close combat) and Run Slide, but that's all he really needs. He takes significanly less damage from falls and has a very slow hypo regeneration rate to discourage hypo use. As OP as he may seems, he is likely to suicide upon Combustion at a close range, so avoid that.

Adds a new character : BGI Sarai or the female BGI Boss.
Sarai, second in command to the BGI-executives, is ruthless, dangerous, highly skilled, and devoted to the BGI.
Combining agility, speed and power she is a force to reckon with.
Sarai uses many new custom made moves and comes with 4 possible outfits.

You can see a full preview of this package in this YouTube video.

As seen in EdT's Boss Battle mod, Barabas fights with smarter melee. Rather than spamming Earthquaker, he fights with faster moves and dodges more using his jetpack. Installs after Brutal AI's modifications to Barabas, so having Brutal AI turned on will not affect this mod.
