Sailor Butress (pronounced Ba-To-Ress) is from the Drama plays only. She follows Sailor Galaxia around like a shadow, conspiring with her, but she's not Chaos- that's a totally different character. Butress only appeared in the first play, the Sailor Moon Sailor Stars. She was played by actress Shiroi Seki.

But why Butress^^*? Funny name, but my guess is that it's a small pun. A butress is a type of architectural support on buildings, mostly seen on cathedrals, that act as supports for the roof and walls on the outside. Sailor Butress is a "supporting" actress;keeping behind the scenes, she helped  Sailor Galaxia along.
