Heckler is a playable character in Knights in the Nightmare.
A pure and innocent young boy, he genuinely believes the world could be made a better place if everyone would try a little harder. While not as brash as Dreyuss, Heckler is very energetic and stands up for what he believes in. Having grown up in Balmore, he has a strong dislike for prejudice. Wunsche saved his life in battle, and now Heckler looks up to him.
- On Wunsche, A Savior: "I'm only able to be here because of Sir Wunsche."
- ON Wunsche, A Savior: "Maybe he's what people consider a hero..."
- On Lakshmi, One of No Hate: "I wonder what she's doing now..."
- On Otto, One Who Saw Much: "Otto sure has been through some tough times, huh?"
- On Chester, Another's Brother: "I heard rumors that Lutecia had a brother?"
- On Latune, The Mehse: "So the Lemonogue are the ones called the Mehse?"
- On Alier, The Oppressed: "It sounds like there aren't many Tiamats left now."
- "Difference in rank or race can be such a bother."
- "Shouldn't rank and race be meaningless? We're people!"
- "If I try my best, the lives around me will improve!"
- "I wonder what the Tiamats and the Mehse talk about..."
- "There's been some shady activity. Stay alert!"
- "There must be some secret between those two races..."
- "We must become demons to rebuilt our kingdom..."
- "Life should be more than loving or hating something."
- "I hear the Tiamats and the Mehse have a connection."
- "We're playing with fire if we don't proceed carefully."
- "I don't think anything can be born from hate."
- "I'm happy to see how much I've grown."
- "I'd hate to be benched because I wasn't strong."
- "Wow, so this is what it's like to level up!?"
- "I'm glad..."
- "Is it because I'm Balmorian? I hope not..."
