- Awesome Music:
- The theme song will suck you in right in due to its mesmerizing melody.
- "Tez Sez" from the episode of the same name. Christian Lanz certainly has the chops.
- Base-Breaking Character: Victor can be seen as this, mostly from how he's a huge jerk. One side thinks he's too unlikable, causes many of the problems of each episode, and feel he never really seems to actually learn anything. The other side thinks he's still a good person even with his flaws, is slowly yet surely developing into a better person, and there are times where he can be sympathetic nonetheless.
- Complete Monster: Chip, from "The Collector", is an antique collector, obsessed with keeping his merchandise in mint condition. Growing unsatisfied with collecting only items, he decided to collect people. He turns them into dolls, where they are conscious, but trapped, a fate which he has inflicted on many people, including Valentino's younger brother. He is more than willing to inflict the same fate on Valentino when he tries to rescue them.
- Ensemble Dark Horse:
- Charlene immediately became popular thanks her Creepy Child personality, cute gothic design, and performance by Cristina Milizia.
- Xochi is gaining popularity thanks to her Action Girl personality, attractive design, and performance by Cristina Valenzuela. The fact that she's also revealed to be lesbian boosted her popularity even more.
- Fanfic Fuel: The finale of OK KO reveals that Mr. Gar's home is Monte Macabre. What kind of adventures could happen with the characters of both worlds meeting up?
- Friendly Fandoms:
- Due to thematic similarities (a two sibling team with differing personalities, living with an older relative for the summer, and being in a small town with supernatural creatures), the series has some overlap with fans of Gravity Falls. However, this has also coincides with a largely one-sided Fandom Rivalry, due to accusations of the show borrowing too many elements from GF.
- Fans of Over the Garden Wall also get along well due to the clashing siblings and the strange supernatural oddities that appear.
- Most fans of the show are also fans of other shows with heavy Latin American culture, the standout ones being ¡Mucha Lucha!, El Tigre, and Elena of Avalor .
- Genius Bonus:
- Chata's house has a double-headed serpent sculpture above a doorway.
- In the flashback telling how Huehuecoyotl got sealed away, the illustration of the god who did it to him is the same as the Aztec depiction of Tezcatlipoca.◊
- Tez's identity is immediately given away if you know anything about Aztec Mythology, namely that "smoking mirror" is also a nickname for Tezcatlipoca and that Tezcatlipoca lost his leg to a winged feathered serpent (Quetzalcoatl) or a crocodile ate his foot, referencing his other backstory where Cipactli ate it.
- Jerkass Woobie: While most episodes portray Victor as a bit of a jerk, the "Welcome to the Underworld" two-parter does portray him more sympathetically; it turns out that many people underestimate or baby him because of his size and the fact that he's the younger brother
- So Okay, It's Average: Reception for the show so far has been pretty much this. It's regarded as being your typical "heroes screw up and must defeat the Monster of the Week to fix everything" type of show, but otherwise harmless enough to avoid being straight-up bad.
- While looking for Valentino, El Colorado comes across Victor's special (lint-covered) jawbreaker, Selena...and starts licking it.
- Lechuza feeds her "babies" via regurgitation. It's not pretty.
- The Woobie: Valentino. Victor treats him like crap and his brother's actions usually get him in trouble. He also doesn't seem to be as popular as his brother in-universe.
YMMV / Victor and Valentino
