[Franken Stein (フランケン・シュタイン, Furanken Shutain), also known as Professor Stein, is the man that changes Sid into a zombie, the strongest Meister of the DWMA. He was Spirit's partner before, due to suffering the effects of Asura's madness, is given a new partner. He is named after the title character of Mary Shelley's novel Frankenstein, with elements of Frankenstein's monster.]
"I can't seem to get my head on straight."
"I have a simpler motive. Experimentation and observation that's all a true scientist cares about. And I am a scientist. Everything in the world is an experimental test subject, of course that includes myself as well."
"All the more reason to dissect one, before the whole species dies off."
"Soul Force!"
"I think I'd like to dissect you now!"
"Spirit Body."
"Double Palm Soul Force. Twin Spears."
"Witch Hunter!"
"Are you helping because you're a doctor? Or is it because you're a Witch?"
"Ha ha ha ha! Promise me something if you're gunna sue go after Spirit first okay?"
"This is fear. That's good then, I had forgotten what it felt like."
"You know about it don't you Witch Medusa? About the Kishin beneath the DWMA."
"Are you ready to fight against fear itself? Will you cross beyond that door? Let your souls make the decision for you."
"You can't even imagine how disastrous things would be if the Kishin is revived. It's madness is like a plague."
"We have come this far. We're just a step away, but the moment the sutures come undone, the fight will start all over again. (He then imagines the tail snake killing him.) And as Medusa said, I'm more likely to be the loser. Her tail snake is pointed directly towards my throat just a hair's breathe away from beheading me. But right now, I can't seem to picture myself being defeated. All I can imagine is dismembering that witch, dissection is what I do best... (Pause effect.) My only chance is to roll the dice and hope I win."
"Made you look."
"Whats good and evil is determined by those of who are in power."
"Where am I? What path should I take? Move ahead, join the new world that's awaiting to be born, or turn back to the old world? Am I still stable or am I being consumed by the madness? Is this the truth that I see, or the fabricated delusions of insanity? Water ever-flows from higher elevations down to lower ground. More and more water collects in one place forming a river. So it is too with the lives of men. Set in their ways, they hate the loss of the old order. They fear change, but what if it's better to fall from higher grounds to join the new river? Old or new where everything is controlled by the order, but that's okay. The only thing I need right now is... to obey the new rules.."
(Professor) Dr. Franken Stein (to Marie): "I'm going to cut you open now!!
"There are some friendships that can never end. It took me a long to realize that, but I finally get it now."
