* The blue sparkles that Michiru emits whenever she shapeshifts is (probably) inspired by the twinkles from Anime/KillLaKill.

** When Mary preemptively corrects Michiru, she looks like Noroi from ''Gamba No Bouken''.

* Probably unintentional (but with Trigger you never know), but when mayor Rose explains that beastmen children have the genes of either one of their parents and not both, the visual explanation shows [[Film/NapoleonDynamite a liger]].

** The coach is a parody of Danpei Tange from ''Manga/AshitaNoJoe'', right down to the eyepatch and being a former (boxer/baseball player).

* Gram Grandma resembles [[VideoGame/SuperMarioOdyssey Madame Broode]].

* Yaba's monstrous rhino form triggered by Nirvasyl Syndrome is partially reminiscent of the mutation of Asura Rhino from ''Anime/OnePunchMan'', especially with the TronLines on his body and after he grows multiple limbs and horns.

** When Mary preemptively corrects Michiru, she looks like Noroi from Anime/GambaNoBouken.

** The whole team and their uniforms are based on ''Film/TheBadNewsBears'' -- even the plot is vaguely similar: Total losers until a new, female pitcher joins the team. Another team they meet is called Film/PinkFlamingos''.

* During the FinalBattle, [[spoiler: the BigBad Alan]] takes on a form that greatly resembles the [[{{Film/GodzillaKingOfTheMonsters2019}} False King Ghidorah]] and even his normal Beastman form looks kind of like something from {{Film/Cats}}. As a bonus, [[spoiler: Shirou's Ginrou form]] has a blue color scheme similar to that of the [[{{Franchise/Godzilla}} True King of Monsters]].

* ''WebAnimation/InfernoCop'' appears on a screen in the first episode.

* During the BaseballEpisode, one of the bears' teammates is based on [[{{WesternAnimation/TheManyAdventuresOfWinnieThePooh}} Winnie the Pooh]]. The announcer even calls him that as the bear escorted out of the field due to multiple injuries.
** Another teammate's beastman form, Jackie's, is based off of Animation/VinniPukh. The russian equivalent to Winnie The Pooh.

* As per usual of Studio TRIGGER borrowing from their favorite things, Shirou's human character design is almost line-for-line identical to Ryo Asuka from the late 1980s OVA, ''Manga/{{Devilman}} - The Birth.''

* From Yoshinari's own ''Anime/LittleWitchAcademia'', TheHero Akko can be seen from behind as a beastman, specifically her rabbit form from the ''Fountain Of Polaris'' episode. Her friend Lotte also appears as a beastman in one shot in the first episode. And like how Andrew was a non-magical human in the series, he can also be seen as a human arresting a beastman, although glasses obscure his eyes.
