: A fictional religion which closely resembles Christianity.
- Straight: Troperianism is the predominant religion of Namespacia, and it is a monotheistic religion whose God consists of three component essences, and who sent a savior down to Earth to redeem man for their collective sinful nature.
- Exaggerated: Every aspect of Troperianism, from the mythology to the structure of the religious hierarchy, has a direct analogue in Christianity.
- Downplayed: Troperianism is monotheistic.
- Justified: Troperianism is a belief system that developed out of Christianity, adapted to suit the denizens of Namespacia.
- Troperianism has aspects of just about every religion except Christianity.
- Troperianism uses many Christian names but it is really In Name Only with no real association used because they thought the names were cool.
- Subverted: Troperianism appears to be closely related to Christianity...but all Troperians actually worship Troperianism's version of Satan.
- Double Subverted: But they only do so to bide their time and stave off Troperian!Satan's wrath until Troperian!Jesus comes to rescue from his clutches.
- Parodied: Troperians worship Dog, whose son, Tsirhc Susej, died for man's sins and return again in the future to save mankind from Natas' evil ways.
- Zig Zagged: Troperianism borrows heavily from Christianity, but also from Islam, Hinduism, Greek mythology, Shintoism, etc.
- Averted: Troperianism is a completely original religion.
- Enforced: The author is writing for a primarily Christian (or culturally Christian) audience, and wants them to be able to immediately identify with the protagonists.
- Lampshaded: "Praise Jesus...I mean...Tsirch Susej!"
- Invoked: A character is forced by circumstances to invent a religion on the spot, and comes with little more than Christianity with some changed names.
- Exploited: It's ridiculously easy for Christians to avoid anyone noticing their not Troperianists.
- Defied: ???
- Discussed: "This...Troperianism...it sounds an awful lot like Christianity, doesn't it?"
- Conversed: "Why do people in fantasy books always just practice some relabeled version of Christianity?"
- Implied: Little about Troperianist mythology is ever actually discussed, but the imagery, symbols, and religious practices all bear close resemblance to Christian ones.
- Played For Laughs: A church for Troperianism and a church for Christianity are side by side. People often walk into the wrong one and it takes hours for them notice.
