Deneb.
Ding! We got a winner!
1. <3
- She has a tendency to talk with hearts in later games <3. Not to mention her class in Knight of Lodis is "Witch <3" (Yes, heart included)
2. Stunning, aren't I?
- Ogre Battle. Being a witch, she has the Stun Cloud move.
3. Not to mention hot
- Tactics Ogre. She has an affinity to fire, and if you do some extra stuff, she'll join your team equipped with a bunch of fire equipment and a fire spell (Nova)
4. And very tempting to look at
- Knight of Lodis. Temptation skill.
5. Makes you wonder why people wanted to kill me when I first appeared
- In her original appearance in Ogre Battle, she was terrorizing a village and you have an option of following the villagers' wishes and killing her. In addition, most early FAQs said that killing her is required for the best ending. Of course we know better now, so nowadays, players just kill her if they prefer to have an easy access to Halloweens over recruiting Deneb.
6. Of course, after that, people just can't get enough of me.
- She became a recurring character in Ogre Battle, the only one to appear in every Ogre Battle game in some way or another, even the Gaiden Games. I'd hazard to say that she's the most recognizable character from the Ogre Battle series.
7. Then again, it's not like they could kill me permanently even if they tried.
- If you get her killed in Tactics Ogre, her death quote has her getting annoyed that she lost another body, implying immortality through spare bodies.
8. I didn't stay beautiful at this age without learning a few tricks, after all.
- The spare bodies thing, which is also the secret behind her eternal youth. Also, a scene in Tactics Ogre has her talking to the sleeping form of Warren as equals and being annoyed that he doesn't just get rid of his aging body, implying that she's as old as he is.
Unused clues:
9. All the better to play around with my vegetables. Or are they fruit?
- Pumpkins. This is the last resort clue in case no one still gets it since there are very few RPG characters as closely associated to pumpkins as she.
10. Did I mention that I'm bewitching?
- And the other last resort clue. She's THE Witch after all.
Your move.
