Underfell Flowey is the flower form of Underfell Asriel. Unlike UF!Asriel, who is unintentionally rude, UF!Flowey is shy, timid, and easily scared. He does not believe in Asgore, his father’s “Kill or be killed” mentality that has spread throughout the Underground since his plan with Chara, his adoptive sibling, ended in failure. He loves singing.
This version of Flowey is not manipulative nor is he a liar. He truly does act as a guide and can even heal you with his pellets. A true friend.

UF Clover and Flowey
Clover and Flowey have been on the run from the Underfell Royal Guard for quite some time. They had stolen a valuable artifact from the kingdom and were now hiding in the shadows of the castle's corridors. Clover, a skilled thief, had managed to bypass most of the security systems, but they knew they couldn't stay hidden forever. Flowey, a large buttercup flower with a face, had been tasked with keeping watch for any signs of pursuit. The two had grown close during their time together, and Clover had even given Flowey a name, calling him "Buddy." As they continued down the corridor, they couldn't help but feel a sense of excitement and adventure, even as they knew the danger that lurked around every corner.
