Renegade Dolly

A Pygmy type Dolly.

This Dolly is the one who killed Matsumoto at the beginning of the manga.

It is different than other Dollies, as it seems to be more aware. It is also possibly stronger and more clever as it managed to defeat three other Pygmy types on its own.

This Dolly shows up one day and seems to recognize Iruma. It and Iruma fight, until it is trapped by Trial and Error in thermogelling polymer. However, it breaks free and continues to pursue Iruma, until help arrives and rescues Iruma. Afterwards, it is still out for revenge against Iruma for cutting his leg off. Three other Pygmy types are then sent to kill him for failing to kill Iruma, but it manages to defeat them on its own and steals one of their legs to replace its missing leg.
