"We have... three... beautiful colors!"
The Shadow Army is a group of shadow sisters who are allied with the 10-Nauties and perform special operations at Big High Grodan's command. It initially consists of Belda, Viviana, and Lyn; later, Viviana defects to Mario and is replaced by Doopley.
Aside from their participation in the War, they are known for being horribly kinky and incestuous. Belda frequently forces the other members of the Shadow Army to participate in BDSM, and she and Viviana apparently once had a baby.
