If you're looking for a guide to all the Deltarune characters we've met so far in the ongoing indie RPG, we've got your back. We've put together a detailed list of all the protagonists, antagonists, and, as is the case in this game, those in-between, so you can remind yourself of who's who before the hotly anticipated final chapters arrive.
If you'd rather dig into Toby Fox's previous title, be sure to check out our Undertale Chara, Undertale Frisk, and Undertale Papyrus character guides. Or, if you still haven't checked out the latest installment of this episodic gaming epic, see our Deltarune Chapters 3 and 4 review.
Here are all the Deltarune characters:
Kris
Deltarune's protagonist is Kris, who, before falling into the Dark World, lives at home with their mother, Asriel, while their brother, Toriel, is away at college. Kris' father, Asgore, also lives in Hometown, residing at his flower shop since separating from Asriel. Kris's adventure begins at school, where they fall into the Dark World with classmate Susie and are introduced to Ralsei before beginning an adventure as a trio.
You might recognize a few names there, and that's because Asgore, Toriel, and Asriel are all characters from Undertale, though it seems like they're a different version of themselves here, as there's no reference to any of the events from Toby Fox's debut. There's also a very real chance that there's a connection between Kris and Undertale's overarching antagonist, Frisk, due to the striking physical similarities between the two, but this is still speculation at this point.
Susie
One of the entirely new characters and new designs in Deltarune, Susie is one of the playable characters besides Kris and functions as an unwilling wingperson throughout the pair's adventures. While starting off as the class bully and generally not a big fan of Kris, Susie's emotional transformation is one of the most charming elements throughout Deltarune, and the character is emblematic of Toby Fox's playful monster design.
Susie is the most willing of the protagonist trio when it comes to violence and can easily slay monsters with her powerful axe. Despite starting off as the class bully, Susie eventually warms to Kris and their new friends in the Dark World. There might even be a budding romance, with Susie and Noelle getting closer with every passing chapter.
Ralsei
Ralsei is the first being you meet after having fallen into the Dark World and is later revealed to be the prince-in-waiting of the separate dimension. Ralsei also functions as a sort of yin to Susie's yang, preferring to stay calm and ACT where possible rather than engage in combat. While much of Ralsei's history is still shrouded in mystery, we're almost certain they've still got a pivotal part to play in the overarching Deltarune narrative.
Lancer
The self-described bad guy of the Dark World, Lancer is the son of the king (a different king, no relation to Ralsei) and the primary antagonist of the first chapter of Deltarune. His goal is to stop Kris and co from reaching the Eastern Fountain, one of the many sources of dark energy his father has opened in an effort to destroy both the light and dark worlds, but as you begin to expect during the adventure, he'd rather have some good friends.
Fortunately, Lancer's wish is answered at the end of chapter one, and his blossoming friendship with Susie is enough reason to turn against his father and join up with the protagonists. Lancer is also the first character we meet with seemingly no relation to Undertale, with Ralsei being a very obvious anagram of Asriel, though we've had no explanation as to why yet.
King
The real bad guy behind the first chapter of Deltarune, King, is Lancer's father and ruler of the Dark World. He's also, as you might expect, the first major boss battle in the series, arriving right at the end of chapter one to try and stop Kris and the gang from closing the Eastern Fountain. Of course, King is foiled, and his son Lancer leaves to join Kris, Susie, and Ralsei as they continue on their quest.
Queen
Chapter two's antagonist, Queen (or Serial Number Q5U4EX7YY2E9N), is the second of the Knight's lackeys trying to open up new Dark Fountains in an attempt to begin the Roaring, Deltarune universe's version of the apocalypse. While there's no mistaking that she's an antagonist, Queen's demeanor is actually quite cheerful, and she'll find a way around battling if she can get people to do her bidding via other means.
Roaring Knight
Roaring Knight is the big bad of Deltarune and has the ability to create Dark Worlds and Dark Fountains of his own. His goal seems to be bringing about The Roaring, an apocalyptic event, and it's up to Kris, Susie, and Ralsei to put a stop to that. At this point in the story, we don't know how it all might play out, but the Chapter 3 secret boss battle with the Roaring Knight suggests that this antagonist is no pushover.
Tenna
Tenna is Deltarune Chapter 3's antagonist and the finest quiz show host in all of the Dark World. With a quick wit and a short fuse, Tenna is a classic Toby Fox character, making Chapter 3 entertaining despite its occasionally repetitive gameplay. The battle against Tenna is also one of the more memorable bouts in Deltarune, hitting you with round after round of minigame challenges that get increasingly frantic as the man with a TV for a head starts to feel the pressure.
Gerson Boom
You meet Gerson Boom in Chapter 4 of Deltarune, as Susie, Kris, and Ralsei discover more about the prophecy. Boom was once a resident of Hometown, but he died before coming back to the Dark World as a Darkner. In the Dark World, Boom authors Lord of the Hammer, a novel that has striking similarities with your adventure so far. He might be old and a little annoying, but if you want to beat the Deltarune Chapter 4 secret boss, you're going to need to get to know Boom pretty well.
Asgore, Toriel, Undyne, and Alphys
Undertale's Asgore and Toriel return in Deltarune, once again acting as the paternal and maternal figures in the protagonist's life, though this time Asgore is much less edgy and vengeful. As of the end of Deltarune chapter two, the pair are still bit-part players in Toby Fox's follow-up, but with plenty of chapters left in the storyline, there's still a lot of scope for them to feature more heavily.
Undyne and Alphys also return, as Hometown's police captain and class teacher, respectively, though, despite incessant shipping by fans, they're still not together. The two play even less of a role than Asgore and Toriel, but it's certainly a nice easter egg for any Undertale fans.
Seam
The Dark World's resident shopkeeper, Seam, is happy to sell their wares to Frisk and the gang to help out on their quest. You can buy useful items like dark candy or darkburgers from the furry shopkeeper, and if you defeat mini-boss Jevil in the first chapter, they'll celebrate your achievements with a special item.
Sweet Cap'n Cakes
This trio of robotic DJs is at first a mini-boss fight but later becomes a trio of shopkeepers helping Kris on their mission to defeat Queen. You can visit them to buy some special battle items, including Susie's Auto Axe, or just to jam out to some Deltarune tunes in style.
Which Deltarune characters are from Undertale?
As we pointed out in the section for Asgore, Toriel, Undyne, and Alphys, all four of these characters are also in Fox's iconic original game. However, while they're the same characters, it seems like Deltarune takes place in an alternate universe, so none of them have any awareness of the events of Undertale, or if they do, they're hiding it well.
