RNGsus is a notable CTYIzen, also referred to as Terence, Atheist Judas (see Atheist Jesus). Nobody calls him by his real name, which is Lorcan O'Broin. He attended CTYI session 1 from 2012 to 2015. RNGsus is pronounced "Ar - En - Jesus" He is called this because he somehow has consistently incredible luck with random events in video games, governed by a Random Number Generator.

On Monday the 28th of June 20 during social time, RNGsus was given a Shiny Torchic as a starter in his first save file of the first copy of Pokemom Omega Ruby version. This happened the first time he tried for it. The probability of this event is 1/4096.
