The leader of the Seven Flowers, elegant, theatrical, and deliberately reminiscent of a romantic anime protagonist. He is charismatic, confident, dramatic, affectionate, and seemingly helpful, frequently posing, giving advice, and assisting others. However, beneath his charming exterior is an obsessive desire to protect Asgore and construct the perfect life he believes Asgore deserves. Being deeply attached to Asgore, viewing him as the person who gave the flowers their extended lives and treated them with love. His abilities include powerful flower-based magic, spinning attacks, projectiles, and several special techniques. He can summon the other six flowers to fight alongside him and combine their power into "Omega Flowery."

A cyan-colored humanoid flower representing Patience. Ironically, she has almost no patience at all, being energetic, impulsive, curious, and enthusiastic about trying new things, particularly likes the idea of humans and games. She has a feminine humanoid appearance and uses a knife and ribbon, directly referencing the light-blue SOUL from Undertale. Her combat style revolves around knife attacks, spinning blades, and patterns inspired by the light-blue SOUL.

The purple flower representing Perseverance. They are an intelligent, nerdy, somewhat arrogant "know-it-all" who is primarily interested in studying. Despite their intelligence, their perseverance is humorously limited to academics. They wear clothing and accessories based on the purple SOUL's equipment, including a notebook and glasses, being associated with studying and knowledge and acts as one of the more analytical members of the group. Fights alongside Aqua uses purple-themed attacks involving notebooks and words.

The hot-headed yet surprisingly cowardly flower representing Bravery. Being a small orange mouse, she tries very hard to appear fearless, but is actually sensitive underneath her tough exterior. She is energetic, emotional, and considerably more aggressive than Green, with whom she frequently fights as a duo. She has a close relationship with Pink, whom she considers her older sister despite Pink not actually being one of the original seven flowers. Her combat equipment references the orange SOUL from Undertale: the Tough Glove and Manly Bandanna. She specializes in physical attacks and represents the idea of bravery as the ability to act despite fear.

The embodiment of Kindness and is arguably the gentlest member of the group. They are exceedingly kind, helpful, and unusually quiet, seemingly having little interest in speaking. Green has a strong association with cooking. Their signature equipment references the Burnt Pan and Stained Apron, and they operate as a helpful shopkeeper throughout the Flower Kingdom, sometimes giving useful items for free. Despite their gentle nature, Green is fully capable of fighting and battles alongside Orange. Their abilities and equipment revolve around healing/support themes, and defensive combat.

The flower of Justice. He is well-meaning, enthusiastic, and fundamentally good-hearted, but extremely gullible. He has a cowboy-inspired aesthetic and personality, complete with the thematic equipment of the Yellow SOUL: an Empty Gun and Cowboy Hat. Repeatedly appears throughout the Flower Kingdom and fights alongside Blue. His combat style incorporates gun-like projectiles and attacks inspired by the Justice SOUL. Despite representing justice, his tendency to believe almost anything makes him considerably less intimidating than his theme suggests. He also has a particularly funny misunderstanding involving Blue and "bluegrass," demonstrating his innocent and literal-minded personality.

The elegant, perceptive flower representing Integrity. He is a dancer whose personality revolves around grace, elegance, kindness, and his belief that love is an important part of life. His appearance directly references the blue SOUL: he has dark-blue skin, light-blue hair tied into a ponytail, a petal-like tutu, and ballet shoes. He normally keeps his eyes closed, opening them for certain expressions, and can also manifest small blue butterfly wings and fly. Blue is associated with dance and elegance and is one of the more perceptive members of the group. He fights alongside Yellow, using ballet-inspired movement and attacks.

Technically NOT one of the original Seven Flowers, but she becomes an honorary member and is treated as a sister by Orange. She is actually a ghost possessing a Mew Mew action figure that became a Darkner in the Flower Kingdom. She is irritable, eccentric, and considerably more confrontational than most of the flowers. She initially works as a shopkeeper and later becomes Chapter 5's Shadow Crystal boss. After being defeated, Orange introduces her to the other flowers, who accept her as part of their family.
