- Acceptable Targets: Getting Back from the Dead with new life and powers, Alex was designed the mission of create suffering in the human race. And he prefers to focus on the scum of the society, like thugs, abusive parents, mobsters and in general evildoers, becoming the Vigilante Man of Santiago.
- Angel/Devil Shipping: In this case, it's more like Human/Devil Shipping. Independently how ambiguous is the relationship between both characters, Diablo fans ofter paires Alex/Diablo and Cénit as the perfect OTP.
- Bizarro Episode: The Infernus arc, Diablo's own version of Dante Alighieri's Inferno.
- Cult Classic: Diablo's influence was so strong that the publication became one of the most emblematic ones since The '90s and actually appears as some of the most successful Chilean comic books ever made. Until today, many Chilean (and Mexican) fans like the comic book, looking new content on the internet (like fanarts) and especially the collections, which are already scanned and uploaded.
- Cry for the Devil: Cénit, in the time she realizes is in love of Alex.

- Germans Love David Hasselhoff: During the Turn of the Millennium, one of Diablo's creators, Mauricio Herrera, went to Mexico to live and test his luck as comic book creator, creating his own publishing, Berserker Comics, and carriying Diablo with him, re-releasing the original 12-issue run of Diablo and making Diablo: Crónicas, a Milestone Celebration for the 10th anniversary of its creation, aided for some Mexican artists and a couple of Chilean ones from the original run.

- Signature Scene
- In the first issue, when Diablo justices a father who beat up to the death to his child hanging him from the Entel Tower is one of the most iconic scenes in Chilean comic books ever. The quote on the main pic was said by Alex moments before the poor man got hanged.
- Also in the final issue of the original run, the Badass Boast Alex said in the end of the page was accompanied of a Summoning Ritual when he fullfills the room (which was already full of mobsters meanwhile he was cornered and close to death) with nothing but demons who devours every single human in the room but Alex himself and an unconscious Carla, protecting her from them.
- La Resistencia recently give us Alex's Final Battle look with a mask of La Tirana's devil and a Tetsuo Shima's red cowl.
- What Do You Mean, It's Not for Kids?: Just like the appearance of anime during The '90s, this comic book was absolutely not for children, especially for the Gorn, a good chunk of almost nudity and strong language.
YMMV / Diablo (Chile)
