Batman: Arkham Knight - 10 Coolest Easter Eggs, Secrets And References Explained

7. Sweet Tooth From Holy Musical B@tman

Okay, so, chances are this is a reference to the actual Batman character called Sweet Tooth, but there's only one Sweet Tooth we recognise in this house, and that's the one seen in Team StarKid's Holy Musical B@tman. (Which you should all go watch immediately if you haven't already.)

Thugs across Arkham Knight's Gotham mention Sweet Tooth by name, calling him the "Candy Killer" and that he'd even used an arsenic strudel as a weapon.

The original Sweet Tooth made his debut in The New Adventures of Batman TV show from the late seventies, utilising candy-themed weaponry in a bid to outdo the Dynamic Duo of Batman and Robin, but it wasn't until 2012 that the character cemented themselves as a true great of the Dark Knight's rogues gallery.

The Sweet Tooth of Holy Musical B@man is a true terror, deploying candy themed puns and poisoned candy against his enemies, and was the main villain to step into the power vacuum created by the Joker's death, which occurs off stage (naturally).

Could a similar version of events have occurred shortly after Arkham City? It's doubtful, but you would like to think ol' Sweet Tooth had some say in the post-Joker order of things, even if he doesn't make a physical appearance in Arkham Knight.

Content Producer/Presenter

WhatCulture's very own resident movie guy, Ewan has been working in the content creation biz for over 10 years now, having started as a freelance contributor to WhatCulture Gaming all the way back in 2015. After graduating with a First-Class Honours in History from Northumbria University in 2017 (where he won a prize for a totally killer dissertation on the Watergate years), Ewan took on the role of Comics Editor at WhatCulture and quickly developed WhatCulture Comics into one of the biggest superhero-focused channels on YouTube. He followed this with a brief hiatus at Screen Rant in 2021, where he worked across the Gaming and Film sections as a writer and editor, before returning to WhatCulture as a Senior Content Producer / Presenter in 2023. He started his own podcast, We Love Dad Movies, in 2022, and has contributed several written pieces to the Eisner-nominated comics website Shelfdust as well. In his current role, Ewan incorporates his love of cinema, comic books, and history into written pieces and video essays for WhatCulture's Film & TV channel, as well as WhatCulture Gaming and WhatCulture Horror, with a particular focus on nineties-era Dad Movies, old school Westerns, and Golden Age Hollywood Noir. John Carpenter is his fave, and he thinks Batman Beyond should never have been cancelled. If that's your vibe, you'll probably like his stuff.
