The Royal Guards are a mini-boss duo the protagonist encounters in the upper levels of Hotland. Shown by their names, they are members of the Royal Guard. Royal Guard 01 experiences romantic attraction towards Royal Guard 02, as portrayed in the dialogues during the battle.
- The guards fight together using "Team Attacks" from the bottom and top of the screen. These attacks consist of:
- Projectiles that drop from top of the screen in a similar fashion to one of Vegetoid's attacks.
- Star-like bullets that move vertically from the bottom and top of the screen.
- If one guard is killed, the other's attacks double in intensity and become much harder to dodge.
- If 02 takes off his armor, the attacks from the top of the screen become erratic and fall out the side of the Bullet Board.
- To spare this duo, one must clean Royal Guard 02's armor, and interact with the Green projectile five times.
- At this point, 01's attacks become shaky and easy to dodge.
- Once 02's armor comes off, whisper to 01 to be honest about his feelings.
- Note that even after meeting spare conditions, they continue attacking the protagonist's SOUL as usual if they are not spared immediately and any other action is used.
- Hey! You! Stop!
- We've, like, recieved an anonymous tip about a human wearing a striped shirt.
- They told us they were wandering around Hotland right now... I know, sounds scary, huh?
- Well, just stay chill. We'll bring you someplace safe, OK?
- ... Huh? What is it, bro?
- The shirt they're wearing?
- ... like, what about it?
- Are you thinkin... What I'm thinkin?
- Bummer. This is, like... Mega embarrassing.
- We, like, actually totally have to kill you and stuff.
- ... you're here.
- So that means Undyne...
- Like, Undyne!

- Whew, bro! That human, | Put me, uh, under mind control! | What was I just saying? | It's a blur dude!! Whoops! [If the protagonist called Undyne in the Laboratory Entrance when the guards were still blocking the path]

- [RG 01] Sure dude! Haha!

- 01 and 02 are looking at each other happily. [Spareable]
- I see two lovers staring over the edge of the cauldron of hell. [Check, Genocide, first time]
- Do they both wish for death? That means their love will end in hell. [Check, Genocide, second time]
- I couldn't stop laughing. [Check, Genocide, third time]
- After sparing them, the newfound couple can then be found at the top of Hotland, just before the MTT Resort, having bought all of the Nice Cream from the Nice Cream Guy. The protagonist is unable to purchase Nice Cream from the vendor.
- If the Genocide Route is aborted by sparing them, they do not appear in this area because the Nice Cream Guy, like the other NPCs, is absent.
- A call from Undyne informs the protagonist of their species - RG 01 a bunny, and RG 02 a dragon, and that RG 01 requested to patrol with RG 02.
- Their in-game sprites also prove that (spr_royalguard_rabbit_d_0 and spr_royalguard_dragon_d_0)
- If the protagonist calls Undyne and Papyrus in the first room they see the Guards in, she goes on to talk about how she believes humans have mind control powers due to an anime that Alphys showed her, and ordered the Guards not to listen to her if she ever defended a human. Later, in battle, after 01 confesses his feelings to 02; instead of saying he was just joking, he blames his confession on human mind control.
- Their sprites are named with the word "bara," which is a misnomer of a Japanese genre of artwork and fictional media that features homosexual men and traditional masculinity made by men for men, known in Japanese circles as "gay manga."
- There are two unused sprites for two more Guards, RG 03 and RG 04. 03 appears to be a bug-like monster similar to a praying mantis and 04 appears to be a feline monster. They have a similar sparing mechanic, being two women who used to be friends but had a falling out.
- The Royal Guards are the only monsters not to have an explicit description of their circumstances in the ending credits sequence. The description is simply "Use Your Imagination," and is up to the players to decide.
- RG 01 and RG 02 are the only sprites in the game that have bouncing animations when talked to.
- Their Genocide Route check description is a direct quote from Banana Yoshimoto's 1988 Japanese novel "Kitchen."
- If the protagonist kills 02 while he has his chest visible, he appears to have his armor back on for a split second before he turns to dust.
