Aku is the shape shifting master of darkness, orignating from the Samurai Jack series. Aku serves as the origin of almost all of the conflict in the Samurai Jack show, and thus is its main antagonist. Aku is the one who sent Samurai Jack to the far future, and in his absence took over the world.[1] Since Jack's sword is one of the few items that can truly defeat Aku, much of his time is spent watching Jack and trying to prevent him from returning to the past.

However, as stated by Demongo —whom may be relaying information to Aku—, Aku is indeed watching. There are also a few items that are based on Aku's appearance in their design.

Sara Bellum (usually referred to as "Ms./Miss Bellum") is the deputy to the Mayor of Townsville, often acting as the true brains behind the Mayor's decisions and how the city is run. Furthermore, her actual face is always off-screen, aside from one short instance where her face was visible in the cartoon. She comes from the The Powerpuff Girls (1998) show.

In FusionFall

Although Ms. Bellum does not appear in FusionFall, broken statues of her are present in the Townsville Park and its infected zone, the Fissure, all of which have her head broken off. This was likely done because her face is always off-screen, which could not be easily replicated with an NPC model. She is stated to still be communicating with and advising the Mayor[5], which confirms that she is still alive, and possibly somewhere inside City Hall.
