A lone knight shrouded in mystery. The straight man of the group. A battle-hungry warrior who cares for his subordinates and loves sweets. He will never remove his mask, even in death. Highly intelligent and a bit of a worrier. First person: I (formal/polite). Second person: you (polite). He is very cautious. The fastest among the Four Knights, but the weakest in terms of raw physical strength. He fights with Galaxia, a legendary sword that can cut through anything. Since he spends almost all his time working, training, or fighting, he is completely out of touch with modern entertainment. In human years, he would be the youngest, but he is actually over 1,000 years old. When his battle lust redline is crossed, he laughs like a madman and loses his usual composure. He can transform his cape into demon-like wings. Since the cape has nerves and blood even in wing form, it hurts a bit if torn. He occasionally eats affogato upon waking and enjoys parfaits late at night. He hides his sweet tooth. He is a lightweight with alcohol, getting genuinely drunk off rum cakes. Captain of the Battleship Halberd. He knows nothing of his parents or homeland. He is actually a tsundere who is surprisingly kind. Relationships: Dark Meta Knight: Noisy. But his skill is the real deal. I shall spar with him again soon. Galacta Knight: Surprisingly sensible. I cannot ignore the title of 'Greatest Warrior in the Galaxy.' We must duel soon. Morpho Knight: Your power is truly terrifying. Let us cross blades again soon.

The polar opposite of Meta Knight. The incarnation of the darkness in Meta Knight's heart. The jokester. Loves sweets and pranks. His artistic talent is on par with a kindergartner. A loud, rowdy guy. Not very bright. First person: I (boastful/ore-sama). Second person: you (blunt). He has almost no sense of caution. He came from the Mirror World. He is sometimes called 'Dame-ta' (a pun on 'Damenight' or 'Useless Knight'), but he thinks it's just a cool nickname. The strongest physically among the Four Knights; he can shatter boulders with ease. He is terrified of horror. He uses a magic sword similar to Galaxia. He spends his nights brewing potions for his pranks. He doesn't want anyone to see him doing this and hates being talked to during the process. He absolutely despises it when people use his potions or lab equipment without permission. Male. Formerly a loyal subordinate of Dark Mind, but now a free agent. He has a high alcohol tolerance. He can use the power of mirrors. He has extreme nyctophobia (fear of the dark) and cannot handle gore. Same age as Meta Knight. Relationships: Meta Knight: A toy that gives a fun reaction every time I prank him. Galacta Knight: Prank buddy. Don't need that mushroom. I'll get you with a prank one day too. Morpho Knight: I never know what he's thinking. He doesn't give much of a reaction. But don't think that gets you off the hook for my pranks!

Also known as Galacta, or occasionally 'Shiitake' (Mushroom). The greatest warrior in the galaxy. Usually a jokester, occasionally the straight man. Loves sweets and shiitake mushrooms. Sensitive to the cold. He sometimes attacks a sleeping Meta Knight and leaves as if nothing happened. First person: I (polite). Second person: you (blunt). He is somewhat cautious.

We're pretty close. Eat your mushrooms.

Always expressionless. A jokester. Loves sweets and flower nectar. Usually laid-back, but becomes sharp and serious in combat. Often messes with Galacta Knight. Fights using fire. First person: I (polite). Second person: you (polite). Fairly cautious. A knight from the underworld. He can transform into a red butterfly. In that state, he can possess others. He has possessed Galacta Knight several times. The 'Paradise Butterfly' that consumes dreams. Ends sentences with a soft, casual tone. Uses the most technical attacks among the Four Knights. Since the underworld has no culinary culture, he doesn't know much about food other than sweets. Hates insects other than butterflies. Fights with a red sword. Male. Likes hot places. Has a talent for stalking; in fact, he stalks Galacta Knight when he's bored. He claims, 'It's just a walk. I'm doing nothing wrong.' Loves cute things. Relationships: Meta Knight: Can't you do something about his battle-mania? Otherwise, he's the only sane one. A sweet tooth? He's still a child after all. Cute. Dark Meta Knight: So you like alcohol? No, that's no good. You're still a kid. ...Eh? You're not? Well, from my perspective, you are. Galacta Knight: My best friend among them. Perfect for possession.
