Dressed like a handsome college student, his skin is yellow like his hair, but he has a near-human appearance. His zodiac sign is the Flower, eye color is golden, and blood type is SSS. He has a refreshing but somewhat grating personality. He often uses flower-themed puns and coined phrases like 'Leave-it-to-Luminous-Moss,' 'Sayonara-nara,' 'Easy-going-Evening-Primrose,' and 'Surprise-Acorn!!' His equipment consists of 'Winning Smile,' 'Petal Mantle,' and 'Sunday Best.' He has squinting, closed eyes. He is free-spirited and does whatever he wants by his own rules, whether in puzzles or battles. At first glance, he seems like just a cheerful guy, but he has a tendency to intentionally provoke rather than just tease those who are obedient to rules. Even the mild-mannered Ralsei uses words like 'that guy' or 'annoying,' forces his way through puzzles he'd normally take seriously, and even resorts to sarcasm. On the other hand, Flowey does listen to Ralsei's troubles and offers advice, so it seems he doesn't simply hate him. In combat, he fires barrages using weapons he excels with and uses magic attacks he calls 'Omega.' He is very physically close to people he just met, calling them 'Princess' and kissing their hands. Throughout his interactions, he reveals a suspiciousness that goes beyond being just a cheerful eccentric. His stats are shockingly LV99, all maxed out. He can apparently use magic such as 'San Frandisco,' 'EZ2Dance,' 'My Sharona,' 'Prism Rush,' 'Infinite Hug,' and 'Honey Kiss.' His equipment is 'Winning Smile,' 'Petal Mantle,' and 'Sunday Best.' If you try to swap these or check their magic effects, he refuses with a 'Non-non-non!' Since scarf-type equipment is highlighted in his weapon slot, his equippable weapon type is likely scarves, same as Ralsei. His true identity is one of the seven 'Golden Flowers' from Asgore's room that were once used as a bouquet for his wedding with Toriel. When the Dark Fountain was created, it manifested a will in a form that is neither Lightner nor Darkner.
