P'den Robalt held a notorious reputation as a criminal figure on the world of Taris, during the time of the Mandalorian Wars. The Falleen Jedi Padawan known as Kamlin, who was among the Jedi trainees stationed at the Jedi satellite academy there, apprehended Robalt at some unknown time. The capture of Robalt was highlighted as one of Kamlin's most significant accomplishments in a Taris Holofeed article from 3964 BBY that focused on the local Padawans.
The character P'den Robalt initially appeared in The Taris Holofeed: Prime Edition, which was a fictional news story presented within the final page of the comic The Taris Holofeed: Prime Edition.
