Tropes:
"That Sci-Fi Guy: A human body exposed to the vacuum of space like that would experience Explosive Decompression. They would literally be ripped apart."
 * Badass Long Hair: Which he wears in a ponytail.
 * Brain Bleach: His reaction to seeing Will Smith's... "hancock" in Wild Wild West.
 * Cameo: He has one in The Nostalgia Critic's review of Star Trek 3.
 * And another in the Critic and Linkara's review of Star Trek 9.
 * Captain Obvious: Dr. Wiki appears to explain various scifi terms that people may not understand well - and things that everyone understands perfectly, such as what a bicycle is.
 * Crossover: He appeared in a "Previously on Atop the Fourth Wall" section.
 * He co-reviewed Titan AE with Marz Gurl on the grounds that it was a sci-fi movie.
 * Explosive Decompression: A case of Did Not Do the Research on his part. In the Titan AE review, there is a scene where two characters are thrown into space, and manage to make it back into a ship, relatively unharmed. The characters in question exhale before leaving the ship.


 * Non-Human Sidekick: Dr. Wiki, a personification of That Other Wiki which is voiced by various people including Linkara and Angry Joe.
 * One of Us: One example: he uses a screenshot of the Black Dude Dies First page in the Final Fantasy the Spirits Within review.
 * Running Gag:
 * The Disaster-O-Matic.
 * The harp when he harps on things in the Final Fantasy the Spirits Within review.
 * The Tape Knew You Would Say That:
