[an exaggerated grieving tone] Boo hoo, boo hoo, uee hee hee. So lonely, lonely, I be... But lo, three visitors standing inside? Who are you few? [a pause to let Ralsei speak] I am innocent, innocent. I just wanted to play a game, game. But the BORING kings found such fun to be a trouble. As punishment, they craved to imprison my body. But I'm fast, fast, clever, clever. They lost the chase and locked up their entire race, building a PRISON around the whole world. Now I'M the only free one. 

[a low, building excitement, possibly in a whisper] Uee hee hee, the key, the key. A marvelous fun is about to break free. Won't you let yourself outside? [a pause, then a more excited tone] Uee hee! Visitors, VISITORS! Now we can play, PLAY! Then, after you, I can play with everyone else, too! 

This is a free line, say any and all in-battle lines you want! My only requirement is you say his 'metamorphosis' line, as that has a very weird tone to it, as well as two other voice lines of his. There's quite a few, so feel free to have fun with this! He's a fun character.
