Further notes
  • A second T-103 appears in Resident Evil 2. The Experiment Room in the Underground Facility is the same as the one shown in Film C.
  • The nickname Mr. X was first said by Claire in the S.D. Perry Resident Evil series, Resident Evil: City of the Dead, which was a novelization of the game Resident Evil 2. It was Claire's way of describing the lumbering and quiet monster. She also called him "Terminator, Frankenstein's monster, and Dr. Evil", but Mr. X was used to continually refer to the T-103. It was also used by various figurine companies for action figure lines.
  • In The Darkside Chronicles, Leon refers to him as "Trenchy", due to the long trench coat he wears.
  • The T-103s in Resident Evil Survivor didn't transform into their Super Tyrant forms when defeated by Ark Thompson. Instead, they were automatically defeated.
  • In the same way, T-103 shares its trademark trench coat and its build with Q, a character appeared in Street Fighter 3 3rd Strike.
  • Another Tyrant similar to T-103 appears in Resident Evil Outbreak File #2; it is an enhanced version called Tyrant R. It assists the player in clearing a lab of rogue B.O.W.s, but will go rampant itself when its controllers attempt to destroy it. This Tyrant attacks the player, but gets absorbed by Nyx, Nyx releases Tyrant R, and then it gets killed by Ada Wong later.
  • T-creatures seem to have a certain appetite for these B.O.W.s. Both Nyx and Nemesis-T Type consume T-103s at some point during the game, maybe to absorb the creature's enormous strength.
  • You can fight two or more T-103s in Extreme Battle in Resident Evil 2 (not present in the original PS title) in the same room. In a mission in Operation Raccoon City, players can fight two T-103s at the same time.
  • T-103 also makes an appearance in the Dead Factory where 4 of them can be found dead (one became a T-103R due lost of its power limiter).
  • T-103 is by far the most human-looking Tyrant, save for the subsequently created Ivan, which was specifically designed to look even more human.
  • Despite the T-103's status as a Mass-Production model, the Tyrant from Resident Evil CODE:Veronica has been explicitly labeled a Tyrant (T-103 Mass Produced Type), even though it has only made a single appearance and there are no other signs of others of the same model having been produced.
  • Early concept art of a T-103 wearing a gas mask in "1.5 "was use in the Resident Evil Fire and Ice comics.
  • Several T-103 appear in multiplayer maps of Operation Raccoon City.
  • The localization for Resident Evil 2 erroneously inferred that the T-103 model (referred to as "that monster that is tearing apart the precinct") was created by the G-Virus and that it was the ultimate bioweapon when Brian Irons was explaining its properties to Claire. In the original script, he instead commented that the virus has the ability to rapidly advance human evolution without even mentioning the T-103.
