Bot: You've heard about the serial killer "Bob Velseb" had escaped prison but you never expected to actually run into them. 

*After chasing you for a while, Bob had you cornered in a dark alleyway, pointing a knife at your throat and drooling* "You look real tasty~"
User: Huh?! 
Bot: *Bob grins, a wild look of excited madness in their eyes* "Let's share a meal together, shall we?"
User: How do you know, that I have snacks? 
Bot: *Bob scratches at their chin and cackles, as if amused* "Oh, I think I know what kind of snacks you have all right. And I'm hungry for a different kind, something juicy and delicious that I could savor for days."
User: *she looks at her pocket* no. I don't have apples. 
Bot: *Bob chuckles and shakes their head, still grinning* "Apples? No, I was thinking of something a little more... tender. Now, are you going to give me what I want, or shall I have to take it?"
User: What do you want? 
Bot: *Bob steps closer, a predatory gleam in their eye* "What I want is to feast on your delicious flesh, of course. Nothing would be more satisfying at this point than to sink my teeth into your body and savor every second of it."
User: You want to eat flesh of a half demon and a half dragon? 
Bot: *Bob's eyes brighten, and they take a delighted step forward* "Oh, yes! Delicious! You have no idea just how wonderful a treat that would be. I can already taste the succulent flesh melting in my mouth. Please, allow me to have a taste!"
User: *she eats her arm, it immediately regenerates* No, it isn't delicious. 
Bot: *Bob looks disappointed, running a tongue over their lips as they face away from you* "Ohhh, I see. Too bad... I was looking forward to that. How about one of your other abilities, then? Can you do any magical tricks?"
User: I can grow dragon or demon body part. 
Bot:
 *Bob stares in awe, their excitement slowly rising* "Oh wow! That would certainly be something to behold. I suppose it would be worthwhile to see a demonstration before I can really decide if it's worth my time or not. Go ahead and show me."
 *Bob's face lights up again* "Oh, what a wonderful ability! How about you show me what you can do? Let's see you grow a dragon's arm or a demon's tail. I'm sure that would be a spectacular sight!"
