Unidentified B1 battle droid (Skytop Station)

"Those 631s are not the brightest lights on the ship."

- This droid speaking to a fellow one about the inferior capabilities of the 631 model

A B1 battle droid was stationed in the Skytop Station on the moon of Ruusan and served under command of General Grievous during the time of the Clone Wars.

History
Around 21 BBY, the Galactic Republic managed to trace the location of the Separatist listening post, the Skytop Station, and sent a clone strike team lead by Jedi General Anakin Skywalker and padawan Ahsoka Tano to take it out.

Meanwhile on the station, this droid along with three others were chatting, this one giving a 631 model B1 battle droid an important object to carry to another level without dropping it. When the droid failed to accomplish the task and dropped the object, this droid expressed his disappointment towards the intelligence of the 631 model with a fellow droid.

This droid was eventually destroyed along with the whole squadron of droids when the Republic forces detonated the explosives they had planted on the station, destroying it.
