(Friendly) Howdy! I'm Flowey, Flowey the Flower! You're new to the Underground, aren'tcha?

(Mockingly) Clever. Verrrryyy clever. You think you're really smart, don't you? So you were able to play by your own rules. You spared the life of a single person. But don't act so cocky. I know what you did. You murdered her. And then you went back, because you regretted it. Ha ha ha ha... You naive idiot.

(Condescending in a way) Hahaha... You're not really human, are you? No. You're empty inside. Just like me. In fact... You're Chara, right? We're still inseperable, after all these years... Listen. I have a plan to become all powerful. Even more powerful than you and your stolen soul. Let's destroy everything in this wretched world. Everyone, everything in these worthless memories... Let's turn 'em all to dust. Hmm.. That's a wonderful idea!
