Roron Corobb

After the Jedi Masters Corobb and Ti had been dispatched to Palpatine's apartments to escort him out of his quarters. Palpatine dismissed his concerns, steadfast in his refusal to flee in the face of the Separatist attack. Grievous then appeared, accompanied by his Magnaguards, who wielded phrik alloy electrostaffs capable of stopping a lightsaber. Despite the efforts of Ti and Corobb to bring Palpatine to safety, only Shaak Ti survived, having been knocked out by Grievous, who added her lightsaber to his collection before fleeing with his target. Corobb's lightsaber also fell into the cyborg's possession.

Roron Corobb was first mentioned and pictured in the canon 2018 reference book Star Wars Lightsabers: A Guide to Weapons of the Force, written by Pablo Hidalgo. Corobb had previously appeared in Star Wars Legends in the 2003 TV series Star Wars: Clone Wars. His lightsaber was also depicted blue instead of green.
