Castor made an appearance in a sneak preview of Daft Punk's "Derezzed" track, displaying his trademark flamboyant traits from the movie.
Disparate accounts of Castor's origin exist. He was reputedly designed and created by Kevin Flynn in TC30 as an interpreter but quickly and naturally exceeded his original directives. Unconfirmed conflicting reports describe his origin as a "low-priority actuarial algorithm illegally co-opted identity of obsolete protocol. More investigation required for verification."
As Zuse, he was involved in Clu's Purge, fighting alongside the Isomorphic Algorithms. After the Purge, he found a need to reinvent himself for self-protection, thus adopting the new persona of Castor. He is known to have a past history with the ISO, Quorra.
Castor's first appearance in TRON: Legacy was when Gem guided Sam Flynn to him at the End of Line Club where Castor was posing as a middle man between those who are seeking Zuse and Zuse himself. Knowing full well of Sam's connection to his father, he eventually revealed himself as Zuse and agreed to help Sam make his exit. This meeting was interrupted when a squad of Black Guards raided the club, revealing Castor's duplicitous connection with Clu. Kevin and Quorra intervened and thus changed the tide of battle, prompting Castor to withdraw to safety. As the trio escaped however, a surviving Black Guard snatched the Identity Disc from Kevin's back, but was himself beaten when Castor blew a hole through him with his cane. Castor, triumphantly retrieved the disc that was his prize all along.
In the aftermath of the battle, Clu paid a visit to the End of Line Club to retrieve Kevin's disc from Castor. The deal was to give Castor complete control of Tron City in exchange for Kevin's identity disc. Clu evidently had no intention of holding up his end of the bargain and simply took the disc, his Black Guards planting Light Grenades on the walls as they left. Castor was left standing speechless - the master of negotiations and the self-proclaimed player of "all the angles" had himself been played. A short time later the End of Line Club was ripped apart by the guardsmen's explosives.
Skills and Traits
As a ruse, Castor acts as an independent program who is secretary to Zuse, determining who gets to see him. In reality Castor is none other than Zuse himself, meaning he can pull a lot of weight in the political world of TRON and is capable of uniting multiple factions to overthrow Clu. He also has skill in getting programs into places, manufacturing fake IDs, and falsifying documents.
Castor is known for his flamboyant, social, outgoing personality. He was in a nonchalant and joking mood when consulting Bartik's proposal on usurping Clu. During the Purge, he had faith in the users, but he had abandoned these views by the time Sam was sent to the Grid.
Castor carries a cane packed with a hidden energy weapon. He notably used this weapon to fire a machine gun-like blast to derez a Black Guard, and also fires it randomly around the club during the battle.
- For the role, Michael Sheen had to wear light blue contacts.
- The symbol on his forehead may be a modification of the Ubuntu logo. This, coupled with the name Castor is most likely a reference to the Castor Project, and in particular the "castor" ubuntu package. Compare with Suse and Opensuse, a Linux distribution.
- the name zuse is possibly a reference to the zuse z3 one of the first fully functional programmable super computers or its inverter Konrad zuse
