Buckle up, gamers. This’ll be a long one (and it isn’t even about TMGC! That one’s got surprisingly few references in terms of names).
You might’ve heard of this project I’m working on called Fourthhack (tentatively. i won’t make that its final name. probably.). Talking about its reference names gets a bit muddy, since its setup of user submitted units means that there’s a huge amount of things flying both over and under my head, so for now we’ll just talk about main story units and major NPCs (maybe one day i’ll do a part 2 where i can show off the unit that’s literally just hit vocaloid Teto).
The required story units also have surprisingly little in the realm of references, though the below image might help explain why:
Only 10 guaranteed units means there’s simply not a ton of space for referencing things. I guess Ioria is kinda similar to Iorys, the town in Etrian Odyssey 5? Look, there’s already a lot of far more obvious and intentional EO references in this game. I might’ve named Gore after the character from SMT: Strange Journey, but at this point I’ve heard enough “is that gore of my comfort gore” jokes that I’m a second away from naming him anything else just to escape the pain.
Getting to NPCs is where things get more interesting. First of all, quick disclaimer about placeholder mugs, as this project’s still in development.
Guildmaster: This is overtly just the Guildmaster design from EO1. He’s not canonically the literal same guy, but I wouldn’t blame anyone for thinking he is.
Gerson (doesn’t have a mug yet award): Not a Deltarune reference, amazingly. Instead, it’s a reference to the party’s protector from the LPArchive EO1 playthrough.
Benjamin and Johanna: Beginning the other overarching Fourthhack trend (things named/themed after musical theatre), these two are named after Benjamin Barker and Johanna from Sweeney Todd.
Bobby: Named after Robert/Bobby from Company. Fun fact: Goldblitzx (who has done a lot of mugs for this hack so thanks oomfie) used the same baseline mug for both Benjamin and Bobby, as a little nod to how the actor she referenced for their mugs was in both roles.
Claire: Named after Claire from Maybe Happy Ending. By the way, I strongly recommend watching all of these shows when you get a chance (if you can’t afford to see them in person it’s not hard at all to find bootleg recordings on youtube or the like).
Fourth: ok this one’s cheating a bit, less a reference and more a lore-justified injoke. The Imperial army that Fourth serves alongside grants its highest ranking officials the titles of First, Second, Third, and so on. This is entirely so Fourthhack can have a character named Fourth. Laugh.
Weber (sorry this loser doesn’t even get a screencap but trust me he’s an important character): Simultaneously a reference to iconic CotA unit Weber (I am Weber.) and famed musical composer Andrew Lloyd Webber (to build off the musical theatre stuff and because naming a character Sondheim or something of the sort would be a bit too on the nose).
Answerer (sorry another NPC that doesn’t get a screenshot but they’re important too): Directly named after The Answerer, one of the ultimate weapons in EO5, and the name was also intentionally chosen to have a similar feel to romhack manakete names such as Feeler and Seer.
Ratatoskr: Pretty obvious name reference (messenger squirrel from Norse mythos), but it’s relevant here because somehow squirrels are a running joke in both Etrian Odyssey (especially EO2 and EO5) and in some FE hacking circles.
F.O.E.: F.O.E.s are functionally extremely dangerous miniboss enemies scattered throughout EO’s dungeons. In EO proper, it’s an acronym for Formido Oppugnatura Exsequens, so I came up with my own equally gratuitous Latin expansion that also kinda forces FIRE EMBLEM in.
Weapons/Items: Many weapons are lifted from Etrian Odyssey, with the more original inventions still trying to keep the feel of something you’d find in a traditional RPG. A consequence of this is that your FE knowledge of weapon tiers will not transfer over at all, though as a slight mercy I at least made the most basic sword/lance/axe/bow all use the Short[WEAPON] naming scheme (Shortsword, Shortspear, Shortmace, Shortbow).
pictured below is only the most comprehensible of lists
Classes: Most classes have Fire Emblem names in their tier 1s and Etrian Odyssey names in their tier 2s (eg. Knight promotes into Hoplite, Swordfighter promotes into Landsknecht, Hunter promotes into Survivalist), with classes that don’t have a clear analogue in one series or another given a fitting name for their appropriate tier. FE8’s monster classes also got a lot of renames to fit EO vibes (including some that intentionally use shortened names and wordplay as if they’re a clever English localization trying to fit things in a character limit).
Bonus: the three unit slots used for Caller/Necromancer spirits are named after Asteria from Araxxor’s EO3 LP, Bellamy from Araxxor’s EO2 LP, and Cheese from the same EO1 LP as Gerson above.

Wow that ended up way longer than I anticipated. If you wanna play Fourthhack uhhhh join retinacord and you can watch in awe as i release random gameplay footage and eventually a public demo, idk there’ll probably be a thread here in a few months once i’m comfortable releasing act 1, for now if you wanna peer at the github and build the rom yourself go for it anyway bye superfriends
