R2-X0

Owned by a Krish mechanic known as Maniac, this modified astromech droid was nicknamed Patchwork. The droid had additional armor plating and was installed with a variety of tools. The unit often emitted a high-pitched giggle after his owner spoke, which many people felt Maniac added to the droid himself.
