Increasing Cleo's stats = increasing other maids' stats (and Ataraxis)...
For Re:LS, however... it might be a different story... might make her a optional boss there... with better stats... and more weapons...
One maid not seen, Mai Versailles (I believe), wields a chainsaw... she gets a statue in AS with her kid sister, Sharric...
Mai could also appear in Re:LS along with any surviving kids kidnapped in 2013 by Ciel (under Aidan's orders)...

That's a shame. I could consider making a custom entity just to see if it'd possible but I'm still working on the Custom Boss Rush for my Lunar Shadow copy. But back to Cleopatre: by optional boss, I mean like WarMech from Final Fantasy/SaGa 1 and 2. In which Cleo is an enemy whose power rivals the game's bosses but isn't a "true" boss so to speak.
Also I've been hearing about a lot of these statues so it'd be interesting to actually see them in Apocalyptic Shadow. I'll also consider suggesting more names for Lunar Shadow enemies who don't already have them.
