Sailor Lead Crow is the second last Animate to be seen in the anime.  She's the most powerful animate.  IMHO, she's the coolest looking.  Her attack is "Galactica Tornado".  When in disguise as a human, Crow calls herself Karasuma Akane.

She had a really odd friend/rival/teacher relationship with Sailor Aluminum Siren.  She was very upset when Galaxia killed Siren.  Lead Crow was later killed by her "new partner" the last, animate, Sailor Tin Nyanko.
