Doctor Mindstein

Doctor Mindstein

"I hope we all don't lose sight of one thing: It all started... with me."

Voiced by: Olivia Steele

The principal antagonist of the Dr. Crafty series, Dr. Mindstein is the diabolically depraved source behind the major events of the main story, starting with the end of Season 2's finale. Unlike Crafty himself, Mindstein plays the role of a Mad Scientist as straight as possible, and she proves it through her villainous experimental endeavors. She plans to one day gain access to powers that would help her create an unrivaled deity for the sake of scientific discovery, hoping to leave behind a legacy for herself, and refuses to cease planning until she finally achieves such a dream.

Worse still, Mindstein is the abusive mother of Nurse Worse and Screw. She harshly experimented on them both throughout their childhoods, even up to their early adulthoods. Because of her, the two sisters ultimately turned into the Frankenstein monster girls that they are today. Nurse thankfully escaped some time ago, but Screw wasn't so lucky.

---

• '50s Hair: She has a notable bouffant hairstyle that's much larger than her head.
• Abusive Parent: To Nurse. One flashback shows her cutting into Nurse's body while she's still awake, and in the present, she's responsible for getting Nurse possessed. Furthermore, other flashbacks demonstrate that one punishment for Nurse leaving the house without her mother's permission is a syringe to her neck. All of this because she doesn't see Greta as a daughter, but as a scientific tool to further her research.
• Artificial Limbs: Reveals one in "I Need a Hero Academia," complete with a giant syringe. It's somewhat ambiguous if Mindstein truly has them, as the one that did was fully robotic.
• Astonishingly Appropriate Appearance: Mindstein's appearance borrows and corrupts some of Sasha's traits, namely her blue skin, pointy chin, and tall, thin build. This resemblance denotes both her function in the story as an Evil Counterpart to Sasha and her interest in the technology of Sasha's race, the Infinia.
• Ax-Crazy: Regularly partakes in torture and mutilation, all with a perky smile on her face.
• Berserk Button: Mindstein loves being in control of any situation or relationship that she's a part of. If her feelings of control are threatened in any way, she lashes out—hard.
  • When she finally has Nurse restrained in "I Need A Hero Academia," she formally introduces herself by slapping her daughter across the face and shocking her, eventually triggering Nurse's PTSD—all because Nurse eluded Mindstein's control for so many years. When Crafty and Class 1-A come to Nurse's rescue, Mindstein once again slaps Nurse when she calls out for Crafty to be careful. At that very moment, Mindstein realizes the threat before her, and she takes out her frustrations about it on the easiest and closest target.
  • In "We're Back! A Crafty Story," a sudden, taunting message from the Crafty Crewmates dares Mindstein to come at them with everything she has—because they no longer fear her. In response, Mindstein loses her cool and breaks her computer screen with a scalpel. Two episodes later, "Player Select" shows Metal Crafty in production in Mindstein's lair, and he's ready by "Old Project, New Look"—the very end of Season 4's second month. It's notably the soonest that Mindstein has ever been ready to strike in a single season. The murderous hatred of the Crew that she instilled within Metal only expedites her latest plan throughout Sonic Month.
• Big Bad: This is not a well-crafted persona; Mindstein is a legitimate Mad Scientist. She's the over-arching villain of the whole show thanks to the deeply personal connection she has with Nurse and the Infinium Relics.
• Brain in a Jar: Her brain can be seen through a glass dome on her forehead. Its purpose was to keep her alive while she upgraded her body, but that wasn't quite enough for her.
• By the Lights of Their Eyes: Her eyes are always visible with a disturbing blue glow. They're even visible in her shadow, giving it an even more disturbing effect.
• Cerebro Electro: Doctor Mindstein is a very smart Mad Scientist. Not only is she experienced in some of the same fields as Nurse (biology and medicine especially), but she's also experienced in robotics and has even dabbled in the arcane. While not her primary means of offense, she can electrify her hands to deliver quite a shock. Unlike Nurse's ability, Mindstein's is not predicated on her love and care for another person; she can simply activate the ability whenever she wants. Oftentimes, it's used to suit her abusive whims, such as how she uses it as her warped form of discipline for Nurse in "I Need a Hero Academia." There, Mindstein slaps Nurse with her electrified hand, triggering Nurse's PTSD.
• The Chessmaster: By studying every episode Crafty releases, she came up with a clever plan to capture the castle with little resistance, kicking off the plot of "I Need a Hero Academia." She made sure to have Screw give Crafty a Megaton Punch to get him as far away from the castle as possible, knowing about Sasha's possession of his body and not wanting her to meddle in her scheme. As for the other co-hosts, Mindstein had her Doc-Drohnes launch the assault quickly to get past Crystelle's clairvoyance and electrified the dungeon bars so neither Pepper nor Messi could squeeze through them. And that's not even accounting for the robot clone of herself she sent to attack the castle in her stead. The true Mindstein stays in her laboratory, studying the outcome of the subsequent fight.
• Control Freak: Mindstein feels most content when she's orchestrating every single aspect of her life, and she makes sure that nobody forgets it.
  • The flashbacks in "Socializing is Arcane" and "GEMS! Truly Outrageous" demonstrate how Mindstein uses coercion and physical abuse to keep her children from going out of line. This behavior is a huge reason why Nurse is so traumatized by her mother; in the former episode's flashback, Nurse flies into a panic when she realizes she's late to return home, and the flashback ends just before Mindstein finds her and administers her punishment. In the latter episode's flashback, Mindstein disciplines Nurse again for sneaking out of home, and the punishment is shown: she violently shoves a syringe with a suspicious fluid into Nurse's neck. Nurse exits both flashbacks in the throws of panic attacks.
  • "I Need a Hero Academia" explores Mindstein's scorn towards Nurse for running away from their home. With Nurse completely restrained, Mindstein is free to assert her control over her in Part 1 by degrading her physically and emotionally. She clearly delights in Nurse's broken, desperate responses to each blow. When Crafty comes to the rescue and Nurse is eventually freed in Part 4, Mindstein lashes out at Nurse for her loyalty to Crafty. Upon realizing that no amount of convincing or coercion will sway Nurse to her side, Mindstein decides that killing her would be the best way to regain control. This lapse in judgement ultimately leads to her defeat... or rather, it would have, had this Mindstein not been a robotic duplicate. The clone's wrecked body produces a hologram of the real Mindstein, who taunts the heroes and reveals that, because surveillance was her only goal, she had been in control of the situation the entire time.
  • The scope of Mindstein's authoritarian parenting style with Nurse—back when she was Greta—is expanded upon in "School Days of Yesterpast's" flashback. Once her daughter became a late teenager, Mindstein saw it fit to send Greta to high school. Mindstein was completely transparent about her intentions behind her decision: this small taste of freedom was only an incentive for Greta to continue staying at her side. To drive the point further, Mindstein only turned Greta loose after establishing her high expectations and the consequences of failing to meet them. Greta replayed this conversation in her head as she made her way to her first class. From Greta's uncomfortable body language and hesitance to speak with anyone, she clearly knew that she was never truly free.
    [In the flashback, Greta wades her way past the many students in her high school, refusing to make contact with anyone. Her last conversation with her mother echoes within her mind...]
    Mindstein: Remember, Greta: I'm doing you a favor. Be grateful that I'm making this allowance for you. You know the deal?
    Greta: Y-yes, mother. N-no more trying to get out.
    Mindstein: And remember what I instructed.
    Greta: 'Say nothing... Don't disappoint you...'
    Mindstein: 'Or there will be... consequences.' Good girl. I'll reclaim you at the end of the day. Don't defy me~.
• The Dreaded: Just the mere mention of her name makes Nurse react in fear and for very good reason. Nurse completely froze when Mindstein raided the castle, leaving her completely defenseless as Screw effortlessly knocked her out.
• Dr. Fakenstein: Between her name, her depiction as an evil scientist, and being the mother of two Frankenstein monsters, Mindstein pretty much fits the bill. She also incorporates some elements of the Monster herself with her blue skin and stitches.
• Establishing Character Moment: The final scene of "Yugi Vs. Sakura" is Mindstein's quiet, early introduction to the show, and it builds up the threat that she poses before she's properly introduced in Season 3. After filming is finished, Nurse collects some mail and discovers a mysterious package. It's addressed to someone named Greta, and the sender is labeled as "Mom." After some initial confusion, Nurse seizes up, subconsciously realizing her mother sent this package to her thanks to a horrifying memory of their time together. In it, a still conscious Nurse watches as Mindstein conducts deeply unethical, violent surgery on her. Aside from a domed brain, the only feature that Nurse can remember seeing is her mother's unhinged, remorseless smile staring her dead in the eyes. Once the flashback ends, Nurse finds herself possessed by Bakura for the duration of Yu-Gi-Oh Month, implying that Mindstein is now controlling gods and other powerful spirits to continue abusing her and the other crewmates.
• Evil Counterpart:
  • The similarities aren't quite as pronounced as those between Nurse and Screw, but Mindstein is an eviler answer to Crafty. Both are tall, thin Mad Scientists who revel in their villainy and are accompanied by a short, plump assistant. However, Crafty is a fundamentally good person acting the part of a mad scientist; his relationship with Nurse is founded upon genuine, mutual love and understanding. Mindstein isn't acting; she flaunts her moral bankruptcy through almost everything she does, and she only has Screw in her life thanks to gutting her humanity, turning her into a mindless drone.
  • Mindstein serves as a malicious parallel to Sasha. In addition to their physical similarities, they are both figures from the two main Crafty Crewmates' pasts that greatly affected who they are today in negative ways. However, whereas Sasha's damage on Crafty was unintentional and born from her inexperience with romantic relationships, Mindstein's damage to Nurse is deliberate; she coerced her into compliance at every given moment until Nurse escaped their household. Both characters also want to involve themselves with the Crewmates' lives in the present, with Sasha looking to benefit them with her support and Mindstein looking to benefit herself through their defeat.
• Evil Is Bigger: Among the cast members with typical human proportions, Mindstein is one of the tallest characters on the show. Discounting her hair, she only slightly surpasses Pepper's overall height. However, Mindstein's eye level sits much higher than Pepper's—As shown in this height chart, Mindstein's sits right at the seven-foot mark, while Pepper's is just above the six-foot mark. Thus, Mindstein seems even taller by comparison.
• Evil Laugh: She pulls off a few disturbing ones, mainly during the Season 3 trailer and after she successfully takes over the castle.
• Evil Matriarch: She's Nurse Worse's mother and she's bad enough to bend at least two villains from other shows to her will.
• Faux Affably Evil: Mindstein barely puts forth a veneer of motherly politeness, which she gleefully drops the moment an opportunity presents itself. This aspect of her character is showcased when she and Crafty meet for the first time in "Magic Kingdom Mania." She thanks Crafty for taking care of her daughter... before immediately siccing her other daughter on them them to initiate her takeover of the castle. Later, "I Need a Hero Academia's" first part houses a scene where Mindstein holds a moderately polite conversation with the captive Nurse ... in between prolonged denigration and harsh (sometimes electrified) slaps to the face.
• First-Name Basis: How Mindstein chooses to address her daughters provides some subtle characterization regarding how she treats them:
  • Unlike how she addresses Crafty, Mindstein almost exclusively acknowledges Nurse with the name she gave her: Greta. Based on Nurse's traumatized reactions to the name throughout the series, it's implied that Mindstein's word choice is a manipulation tactic; she knows how poorly she treated Nurse and will gladly trigger her resulting PTSD until she's forced into compliance. And based on a conversation the two share in "I Need a Hero Academia," it's implied that the tactic also stems from her dislike of Dr. Crafty as a whole; it reminds Mindstein of her failure to keep Nurse under her control and, consequentially, how far she strayed from her ideals.
    [Nurse snaps out of the flashback, hyperventilating as all the emotions hit her at once.]
    Nurse: You... You made me. You're... my mother!
    Mindstein: That's right, Greta... I created you. I brought you into this world, raised you, molded you, and made you what you are now.
    Nurse: I was alive... I had a life, and then... You... killed me!
    [Mindstein smiles without a hint of remorse.]
    Mindstein: Ahehehe... guilty.
    Nurse: ... Why...?! ...HOW COULD YOU DO SUCH A THING?!
    Mindstein: You were supposed to be my greatest creation: the successor to my machinations. But somewhere along the way...
    [Mindstein reaches a hand out and harshly clenches it into a fist.]
    Mindstein: ... You began to slip from my grip.
    [A quick flashback plays as Nurse remembers the time when she snuck out of home at night to meet Crafty at the beach.]
    Mindstein: You disobeyed me! And then you tried to escape me! So I took measures to make sure you wouldn't run away again...
    [The flashback ends. Mindstein has turned away from Nurse.]
    Mindstein: Despite my calculations, you resisted and managed to escape. And then that idiot found you.
    Nurse: Crafty...
    Mindstein: Yes... Such an embarrassment. To think he managed to hide you away all these years, my instrument...
  • In stark contrast to Nurse, Mindstein never calls Screw by her real name: Hazel. Her dismissive treatment of Screw in favor of Nurse throughout the series implies some impersonality between them, that Mindstein sees Screw less as a daughter and more as a means to an end. This outlook on her second daughter is explicitly discussed in "ADnDiction," where Crystelle reveals that Screw was an unexpected, unwanted twin that Mindstein neglected until Nurse's escape. Even then, she's expressly a temporary substitute for Nurse until she's back under Mindstein's control, as Nurse houses the only Infinium Heart replica that Mindstein was willing to make.
• For Science!: Her justification for all the horrid acts she's committed, and the backbone behind all of her schemes.
• A Glass of Chianti: She's sometimes depicted holding a glass of a blue cocktail.
• Godhood Seeker: Her ultimate goal: using Nurse Worse and all of the Infinium Relics, she wanted to open the Infinium Door and let the eldritch energy flow throughout the multiverse, with herself at the center of it all researching the results.
• Hijacking Cthulhu: So far, she managed to get two Eldritch Abominations with immense power to work for her, while suffering no retaliation from them! And, as noted above, she plans on doing this with the Infinia too.
• Icy Blue Eyes: She has pale blue eyes, which is fitting for her cold, sinister personality.
• Improbable Hairstyle: Mindstein bears an impressively large bouffant. Strangely, all of it is somehow distributed behind her head, seemingly to make her domed brain that much more visible.
• Just Toying with Them: While Mindstein could feasibly confront the Crafty Crewmates whenever she wants, she likes to mockingly play along with their show's monthly themes, especially by coinciding her plans with them. By doing so, she's also asserting herself as an inescapable aspect of the show.
  • For her first malicious act against the show, she sends Yami Bakura to possess Nurse, right in time for Season 2's Yu-Gi-Oh Month. The month begins with "Best Yu-Gi-Oh Monsters," with Crafty and Messi conducting business as usual before Bakura starts making things go wrong at the end.
  • When Mindstein successfully steals Crafty's Castle in "Magic Kingdom Mania"—the final episode of Disney Month—she caps off her attack with a bastardized Walt Disney quote. During the ensuing Hero Month, Mindstein stores the captive Nurse in a giant device reminiscent of one from the month's source material.
  • Season 4 sees Mindstein construct an analog to Metal Sonic, Metal Crafty, who she holds off on unleashing until the Crew's Sonic Month begins. The resemblance is more than superficial, too; Metal Crafty's Power Copying abilities and his single-minded focus on defeating Crafty are lifted straight from Metal Sonic's Sonic Heroes incarnation. What's more, Mindstein took Metal Sonic's betrayal in that game into account; thanks to the Dr. Crafty reruns, she has extra precautions in place to dissuade Metal Crafty from acting against her.
• Karma Houdini: Since she was in her lab the whole time during "I Need a Hero Academia," she was never in any danger of facing Crafty and Class 1A and managed to get away scot-free to continue her schemes.
• Knight of Cerebus: The show's previous villains were either harmless or hilarious. But the instant this lady appeared, she established early on that she means business.
• Large and in Charge: She has a powerful Frankenstein Monster and killer robots to serve her, and according to the official height chart, she towers over most of the cast at 7' 5".
• Laughing Mad: Mindstein cackles more and more as her schemes in "I Need a Hero Academia" fall apart thanks to Crafty and Class 1A. Of course, that was just the duplicate. Following its demise, the real Mindstein claims the cackling is a quirk in its design, and that she herself doesn't laugh nearly as much under pressure.
• Lean and Mean: In contrast to her pudgy and kind-hearted daughter Nurse Worse, Mindstein is as thin as she is evil.
• Leonine Contract: Mindstein is fully prepared to recruit evil deities into her ranks for her plans—she just always ensures that they are firmly under her thumb before they even reach an agreement. "Something Weird This Way Comes" is the first episode to show how her recruitment process works. After reviving Bill Cipher in "Charablanca," Mindstein immediately traps him in a crystal ball prison that he absolutely cannot escape from without her influence. She presents Bill with a simple deal: if he wants complete freedom from Mindstein, he must do some reconnaissance work, in which he searches through Crafty's mind for any information regarding his connection to the Infinia. The moment that Bill starts disagreeing with her terms, Mindstein draws the Infinium Flute and plays a tune to torture Bill into compliance. It's implied that she used the same method to manipulate Bakura into serving her for Yu-Gi-Oh Month.
• Mad Doctor: An expert in medical science and anatomy, and an insane murderer with delusions of playing god.
• Morally Ambiguous Doctorate: Even more so than Crafty himself!
• Non-Action Big Bad: It was revealed to be the case in "I Need a Hero Academia" as the Mindstein Crafty and the others defeated was a robot clone, while the real Mindstein spent the story arc watching the events unfold from the safety of her own lair.
• Obviously Evil: Just look at her! Her design makes Crafty look subtle in comparison!
• Offing the Offspring: In order to turn her daughters into Frankenstein monsters, this trope naturally comes into play.
• Playing with Syringes: Her experiments involved murder, mutilation, and playing with forces she could not comprehend, all just to devise the ultimate tool for conquest and research.
• Purpose-Driven Immortality: In her case, her purpose is to become truly immortal, not just a simple brain continually sustained via replacement bodies and upgrades. And to get that, she seeks the powers of the Infinia and the secrets of the universe.
• Psycho Electro: Able to produce electricity from her hands, mainly for Electric Torture and Mind Raping.
• Really 700 Years Old: Her pursuit in scientific studies has led her to be alive for hundreds, maybe thousands of years. It wasn't enough for her, as she knew she'd die eventually no matter how long she's lived for.
• Red Oni, Blue Oni: The Red to Screw's Blue. While Screw is eerily calm with a monotone pitch in her voice and barely any expressions coming from her face, Mindstein is much perkier and has her face locked in a near-constant smile.
• Scary Stitches: Comes with the territory of being a Frankenstein monster, but unlike Nurse Worse she's truly scary.
• Silence, You Fool!: Prone to shout this at Nurse for speaking and for singing. It's unknown if the real Mindstein would do this as much as her more unstable clone, but it's likely she would.
• Sinister Silhouettes: Up until Episode 70, she was obscured in shadow. Only her eyes, mouth, brain, and the faintest details of her clothes could be seen.
• Slasher Smile: She must really enjoy her evil schemes as she's prone to this quite often, usually when torturing her victims.
• Spikes of Villainy: She has thin spikes adorning her gloves, boots and sides of her head. They evoke the syringes that she's fond of using, and "I Need a Hero Academia" shows that she extends this motif to her Doc-Drohnes' weaponry.
• Vile Villain, Saccharine Show: Considering her Establishing Character Moment involved mutilating her daughter, it's pretty safe to say she's much viler than all the show's other characters!
• Villainous Breakdown:
  • Throughout the last part of "I Need a Hero Academia," seeing the power of the Relics used against her caused her to lose quite a few more screws than she already had. This is noted by the real Mindstein to be a trait more associated with her robot clones, but the point still stands.
  • After Hero Month, Mindstein has a small breakdown at the end of "We're Back! A Crafty Story!" As usual, she's watching Dr. Crafty to study up on her opponents. What she doesn't expect is when Crafty, Nurse, and their friends directly addresses her and dares her to attack again. Their boasts actually strike a nerve; Mindstein silently tosses a scalpel into her screen and breaks it, visibly outraged that her targets are no longer afraid of her. Notably, unlike the Mindstein who broke down in the Season 3 finale, this one is the real deal.

Screw

Screw

"You're not just in trouble... You're screwed."

Voiced by: VanityPride

Mindstein's younger daughter and right-hand assistant, Screw is a powerful Frankenstein monster girl who was introduced alongside Mindstein herself at the end of Season 2's finale, albeit as a silhouette. Unlike her older twin; Nurse Worse, Screw emotes very little and only seems to speak in a monotone manner. What she lacks in true emotion, however, she makes up for with high levels of raw strength and complete loyalty to Mindstein. This loyalty goes as far as having Screw address her mother as her "master" perpetually, although her true feelings towards Mindstein appear to be ambiguous.

---

• Always Someone Better: Agrees to Mindstein's 'upgrades' to not fall behind her sister, as seen in the post-credit scene in the Season 3 finale.
• Astonishingly Appropriate Appearance: Like Nurse, Screw happens to have discolored patches of skin. They're almost identical to her sister's—except the one on her face, which is mirrored. It subtly hints at how Screw is a dark reflection of what Nurse became.
• Ax-Crazy: Despite her emotionless exterior, Screw is just as bloodthirsty as her mother. This quality becomes increasingly apparent throughout her confrontation with Class 1-A in "I Need a Hero Academia." She gains a manic look in her eyes as she catches Deku's punch and crushes his hand, and she makes some colorful threats toward Crafty as he somehow survives every one of her hits. When she does the latter, her voice noticeably raises a little out of clear outrage at Crafty's durability.
  Screw: I don't know how you keep surviving my attacks, but I'm going to find out how many it takes before you eventually stop breathing.
• The Brute: Despite being quite intelligent, Screw chiefly acts as the brawn to Mindstein's brains. She's got more than enough power to spare for the role, something proudly demonstrated when she effortlessly trounces Class 1-A in "I Need a Hero Academia."
• Body Horror: Unlike Nurse, Screw only has one permanently attached bolt placed in her head. It's impaled all the way through her skull, with the tip poking out from the other side. However, the bolt has just enough clearance to turn, letting it serve as a dial that controls her power output.
• Cain and Abel: The Cain to Nurse's Abel. She doesn't hesitate to attack Nurse Worse on her mother's command.
• Cyborg: After her defeat, Screw returns to Mindstein's lair a bloody pulp...and with open wounds revealing metal instead of muscle, revealing the true extent of her mother's experimentations thus far.
• Dark Action Girl: She's shown to be just as capable a fighter as Nurse, easily knocking her out and sending Crafty flying out of the castle, both with a single punch. And that's not even getting into the Curb-Stomp Battle she delivers to Class 1A...
• Dark Is Evil: In contrast to the bright colors and clothes her sister and mother wear, Screw wears an all-black outfit with shades of dark red and pink, and her skin palette is a much duller gray.
• The Dragon: She's Mindstein's right-hand woman, always accompanying her in her schemes.
• Emotionless Girl: Even during her childhood, she almost never raises her voice, and her default facial expression is a dull frown.
• Evil Counterpart: Mindstein raised Screw to be her exact answer to Nurse Worse. To wit, Screw is also a plump Frankenstein monster in service to a mad scientist, one who's truly evil compared to Crafty. She also demonstrates what Nurse would become if she remained under Mindstein's control her whole life—whereas Nurse is exuberant and generally joyful thanks to her time with Crafty, Screw is, for the most part, an emotionless husk. To emphasize this idea, Screw's color scheme is identical to what Nurse's was before Mindstein started experimenting on her.
• Fat Bitch: She's just as big as her sister, but nowhere near as nice.
• Flesh Golem: Much like her sister, Screw is another Frankenstein's Monster-inspired monster girl, having the same discolored patches, just mirrored and under a different color palette. There's no word on whether she takes formaldehyde baths to maintain her body's quality, however.
• Given Name Reveal: As revealed in episode 65, Hazel.
• Laser-Guided Karma: Screw is responsible for sending Crafty flying across the globe in "Magic Kingdom Mania." She not only sends him exactly where he needed to be—right before the U.A. High School campus—but she suffers a similar defeat during the last part of "I Need a Hero Academia." Nurse Worse, Screw's Good Counterpart and older sister, delivers Screw a sound beating and tops it off with a Megaton Punch of her own, avenging Crafty and mirroring how the Season 3 finale started.
• Lobotomy: It's strongly implied that Screw became who she is today thanks to Mindstein tampering with her brain. Her relative lack of emotions, her straightforward, unenergetic manner of speech, and the screw impaled through her head are dead giveaways to such a fate. Mindstein also wordlessly reveals Screw's condition to Nurse at the end of their conversation in "I Need a Hero Academia" Part 1.
  Mindstein: ... Now that I have you back, I can finally correct this little mistake that you became. And my plans... can finally continue.
  Nurse: Plans...? What plans...?
  Mindstein: Oh, you don't need to worry yourself with that. You won't have a mind to worry about anything, soon enough...
  [As Mindstein exits the lab, she passes by an awaiting Screw in a doorway. As if to illustrate her mother's point, Screw blankly stares at Nurse for several uncomfortable seconds. The sisters lock eyes, with the implications of Mindstein's threat slowly dawning on Nurse... Screw finally leaves, at which point Nurse breaks down.]
  Nurse: Crafty... Help me... I need you...!
• Meaningful Name: Her name comes from the screws lodged in her head and arms.
• Megaton Punch: She's strong enough to punch Crafty from his castle in Florida all the way to U.A. High School in Japan. That's about 7,300 miles away, just under a third of Earth's circumference.
• Muscles Are Meaningful: She gains a notable muscle increase when she turns her head screw and is practically a nigh-unstoppable fighter because of it.
• Not So Stoic: While normally emotionless, she becomes much more unstable and sadistic during a fight, even indulging in taunting her opponents with how she's going to destroy them.
• One-Woman Army: Best demonstrated when she takes down all of Class 1A by herself, even managing to Punch Catch one of Deku's strongest attacks.
• O.O.C. Is Serious Business: In the final scene of "Crafty Horror Picture Show," Screw frees Metal Crafty and vows to repair his voice so they can discuss something privately. It's noticeable that Screw is, for the first time on the show, acting without Mindstein's direction, a detail assisted by Mindstein's complete absence from the scene. Screw clearly does not want her mother to know about what she's doing or what she's thinking about.
  [The last scene of Crafty's Castle fades to black, transitioning over to Screw opening a door to a dark room. The camera cuts from in front of her to behind her to show what she is looking at: a worn out Metal Crafty, barely able to stand on his own. Screw hurries over to pick him up, with Metal propping himself on her shoulder.]
  Screw: Are you all right?
  [Metal silently gestures towards where his mouth would be.]
  Screw: You've been screaming so much... Your voice chip has short-circuited.
  [Screw quietly guides Metal towards the exit.]
  Screw: Come with me. I'll try and fix your voice. We've got things to discuss.
• Power Limiter: The screw embedded through her head controls her power output. Quarter-turning it allows her to take down all of Class 1A in "I Need a Hero Academia," and half-turning it allows her to go toe-to-toe with Nurse's super mode in the same finale.
• Perpetual Frowner: Her default expression, even in flashbacks.
• Pintsized Powerhouse: Being Nurse's twin sister, Screw is identically short in stature. "I Need a Hero Academia" showcases how she's also quite a dominating presence in a fight, though when push comes to shove, Nurse is a step ahead of her.
• Red Oni, Blue Oni:
  • The Blue to Mindstein's Red. While Mindstein is much perkier and has her face locked in a near-constant Slasher Smile, Screw is much calmer with a more monotone pitch in her voice and barely any expressions coming from her face.
  • She's also a Blue Oni to Nurse Worse's Red, as she's more energetic and emotional than Screw is.
• Scary Stitches: Comes with the territory of being a Frankenstein monster, but unlike Nurse Worse she's truly scary.
• Stout Strength: She shares her sister's exact physique, and she's strong enough to knock Nurse out in one punch.
• Theme Naming: Her name is Hazel and her sister's name is Greta. Does that sound familiar to you? The reference extends past the names, too, with Mindstein easily fulfilling the role as the witch. Also, both women are heavyset, like they've been kept well-fed.
• Undying Loyalty: Screw obeys Mindstein's orders without question; the only thing that could stop her from doing so is putting her out of commission. However, whether Screw's loyalty is genuine or merely motivated by the threat of punishment is left up in the air.
• The Watson: Throughout the story segments of Episode 72, she kept asking Mindstein about her motivations and fascination with the Infinia, which by extension allows her to explain it to both Screw and the audience.

Metal Crafty

Metal Crafty, AKA Project: Eisen Schlau

"Let's. Get. Crafty..."

Provoked by the Crafty Crew's dare in "We're Back! A Crafty Story," Mindstein sets Project: Eisen Schlau into motion. The result is yet another powerhouse in her ranks: Metal Crafty, a direct answer to the Crew's Sonic Month. This robotic duplicate of Crafty has been subjected to non-stop reruns of Crafty's show, so much so that he deeply loathes the crew and is out for their blood. Despite his murderous hatred, Metal bides his time throughout Sonic Month, acquiring data on every single member of the Crew to mimic their abilities for his own ends. He has a much more tempestuous relationship with Mindstein than Screw, as he's unafraid to question her decisions and will occasionally lash out if he doesn't get his way.

Metal Crafty was designed by ToxicSoul77, who also happens to be Messibelle's voice actress.

• Astonishingly Appropriate Appearance: To emulate Crafty's long, flowing lab coat, Metal has several metal plates extending downward from his back. Altogether, they resemble a bird's tail fanning out, matching his bird-like proportions and evoking the idea of a sinister bird of prey.
• Bilingual Bonus: Taken literally, "Eisen Schalu" means "Iron Clever." In other words, this robot's project name is a German rendering of "Metal Crafty."
• Corrupted Character Copy: Metal Crafty borrows a lot of concepts from Metal Sonic—specifically how he appears in Sonic Heroes. Both are robotic duplicate villains created by their series' main antagonists, and each is based on their works' main protagonists. However, whereas Metal Sonic fully believes he's the real Sonic and wants to prove his superiority through world domination, Metal Crafty recognizes himself as his own person and simply wants his basis dead. This is due to Mindstein rigorously conditioning him to hate the real Crafty and his show. It's reached the point where that hatred evolved into crippling trauma, which Metal Crafty firmly believes he'll only heal from if he eliminates its sources.
• Evil Knockoff: Metal Crafty is Mindstein's robotic duplicate of the real Crafty, being an answer to his basis in much the same way that Screw is to Nurse.
• Human Disguise: Throughout Sonic Month, he's perfectly capable of disguising himself as Crafty, and he even mimics his personality and opinions with impunity as he hosts the Characafe and Top Ten Tub segments. The cohosts only discover the ruse upon stumbling into the real Crafty, approaching them from another room and completely unaware that today's work is done.
• Intangible Man: Thanks to copying Messi, Metal is able to disperse himself into a liquid. It comes in handy when avoiding getting his head smashed in by Nurse or beating a hasty retreat, both first demonstrated in "Let's. Get. Metal..."
• Leitmotif: Because he is heavily inspired by the Sonic franchise, Metal Crafty is strongly associated with Sonic music. In particular, starting with "Over the Moonsault," his appearances tend to be accompanied by Sonic Adventure's "The Past," a foreboding track that suits Metal's sinister disposition.
• The Ludovico Technique: Metal's main motivation to fight the Crafty Crew—especially Crafty himself—derives from how Mindstein forced him to watch Dr. Crafty on repeat throughout his development until every little bit of the show enrages him to no end. More than anything, he just wants its production and airing to stop. Metal reveals as much to Crafty himself in "Let's. Get. Metal," and his recount of how he came to be is dripping with resentment for his basis. Notably, not once does his speech implicate Mindstein as the one at fault for his current state—Metal's sights are firmly set on Crafty and everyone he loves.
  Metal: What I want is simple: I want the Doctor to suffer as much as he has made me suffer.
  Crafty: Me?! What did I do to you?!
  Metal: You have no idea what you've done to me. And that's exactly why I must end you. You and this show! I've beared witness to every episode, every poorly timed joke, every dated reference, every frustrating plotline ad nauseum, in an endless loop from the very moment I opened my eyes. Every frame is burned into my memory banks, and the only way I can make it stop is to eliminate you, Crafty. And when I take that heart, those memories will die with you. Today.
• Power Copying: Once he's copied data from his targets, Metal is able to replicate their abilities, as shown when he turns into a liquid-like substance similar to Messibelle. It's implied that he scanned Crystelle at some point off-screen; in "Let's. Get. Metal," Crystelle can't see him through her psychic vision.
• Terminator Impersonator: Metal bears some elements of the Terminator, in the same way that Sonic Heroes' take on Metal Sonic does. He's a dangerous robot with an impeccable human disguise, has glowing red eyes, can turn into liquid thanks to copying Messibelle's data, and is out for blood.
• Trauma Button: Due to how Mindstein prepared him, Metal is naturally predisposed to loathe Crafty's show, enough so that, when it's playing within proximity of him, he grows too angry and annoyed to function beyond screaming and pleading for the show to end. Thus, Mindstein uses reruns of Dr. Crafty to keep Metal in line, as she does when he almost attacks her in "Let's. Get. Metal..." Soon after, as punishment for his failed attack on the Crew's Castle, she locks him away with the reruns constantly playing for the remainder of Season 4. When Screw finds an opportunity to free him in "Crafty Horror Picture Show," she's sees that Metal's an utter wreck, physically and mentally. He had been screaming so much that he's lost his voice, so, unbeknownst to Mindstein, Screw takes him elsewhere to repair him.
  [A beat-up Metal Crafty storms into Mindstein's office, glaring intently at her as he walks inside. Mindstein keeps her back turned to him in her chair as he approaches.]
  Metal: Why? Why did you order me to retreat?!
  Mindstein: What, no 'Hello?' Not even a 'How are we this evening?'
  Metal: Cut the faux pleasantries. What happened back there?! I had a counter to his queen piece! But I couldn't copy Crafty's ability... Explain this to me!
  Mindstein: No.
  Metal: 'No..?' WHAT DO YOU MEAN 'NO?!?!'
  [Seething, Metal continues approaching.]
  Metal: You constructed me for one purpose: to kill that monster! Who haunts me! And TAKE HIS HEART! A heart I can neither disable, nor replicate!
  [Metal prepares to strike Mindstein, who is remarkably calm as he does.]
  Metal: Now... Tell me how I kill him, or I—
  [Mindstein hits a switch on a remote, causing tons of reruns of Dr. Crafty to play on her monitor simultaneously. The sight of them all causes Metal to seize up in fright and fall to his knees.]
  Metal: No! STOP! TURN IT OFF! TURN IT OFF, DAMN YOU!!
  [Mindstein complies.]
  Mindstein: You would do well to know your place, Metal. I've had my own creation turn on me once before... And I refuse to make that mistake again. I won't explain it—because I can't explain it. That fact alone is enough to be troubling to my plans...
  [Mindstein pauses to sigh.]
  Mindstein: ... I cannot continue to underestimate Crafty any longer. But it is fascinating! Two hearts were never supposed to exist. So to see two—a real and a replica—resonate and synchronize in such a way... This will require further research.
  [Mindstein makes her way past Metal towards the door.]
  Metal: Where... Are you going?
  Mindstein: I'm on a tight schedule—Business to run, your repairs to do, preparing the next stages of my master plan, details details. You know the deal. For now... I'll leave you with some... Home entertainment.
  [Mindstein locks her office with Metal inside. The Crafty reruns restart as Metal begins screaming intensely and continuously at them. Just as Mindstein vanishes from view, Screw appears from around another corner. She watches her mother leave before turning her attention to Metal's screaming from within the locked office...]

Doc-Drohnes

Doc-Drohnes

Doctor Mindstein's army of servants.

---

• Distracted by the Sexy: They got distracted by Bakugo's Bishōnen appearance, which didn't end well for them.
• Everything Is An I Pod In The Future: Their mostly sleek aesthetic, white appearance, and glowing blue eyes and brains give off this vibe to their design.
• Gratuitous German: Their name is spelled "drohnes" instead of the English way of spelling without an "H."
• Not So Above It All: While you wouldn't expect them to show any emotions, one look at Bakugo made them practically swoon.
• Mecha-Mooks: Mindstein's chief footsoldiers, all made in her likeness. Their biggest strength is their sheer numbers.
• Synthetic Voice Actor: It's noticeable during the castle raid that they are voiced by a text-to-speech program
• Zerg Rush: How they took over the castle in the first place, overwhelming Pepper, Messibelle and Crystelle with their sheer numbers.

Guest Antagonists

Yami Bakura

Yami Bakura

Voiced by: Ethan Wright

The main antagonist of "The Foreshadow Game," the Spirit of Yami Bakura (AKA Zorc) sends the Crafty Crew into the Shadow Realm. He also possesses Nurse Worse to bring her to the person who revived him: Dr. Mindstein. Before he can do so, Sasha intervenes, so Bakura decides to play a high-stakes Shadow Game with her to decide whether the Crafty Crew lives or remains trapped.

---

• Anime Hair: Bakura wears Nurse's hair down, and he makes it much longer and spikier.
• Arc Villain: Of "The Foreshadow Game."
• Artifact of Doom: The Millennium Ring, natch. Bakura's spirit is stored inside, and he can possess whoever holds the ring for too long.
• Badass Longcoat: He retains his black long coat from the anime.
• Broke Your Arm Punching Out Cthulhu: While he was in control for most of the duel against Sasha, almost killing her in the process, he didn't count on her helping Crafty and his friends to work together and beat him.
• Cold Ham: His voice actor mimics Ted Lewis's performance from the 4Kids dub, giving him this effect.
• Evil Costume Switch: From Nurse's regular outfit to Bakura's clothes from the Dawn of the Duel arc.
• Fat Bastard: Because Bakura possesses Nurse throughout Yu-Gi-Oh Month, he recontextualizes her pleasantly plump appearance into something twisted and vile. He remains just as evil as he is in his source material, gleefully toying with Sasha all throughout their Shadow Game and cackling madly whenever he gains a significant advantage.
• Gender Bender: A male spirit inside a female body.
• The Glasses Come Off: Unlike Nurse, Bakura can see just fine without glasses.
• The Heavy: For "The Foreshadow Game," Bakura serves as the physical antagonist, who imprisons the Crafty Crew in the Shadow Realm and who Sasha challenges in order to save the Crew. However, he merely serves as an extension of Mindstein's evil, and she has a greater presence across the entire show.
• Hoist by His Own Petard: Sending Crafty to the Shadow Realm proved to be a huge mistake, as Crafty used the energy of the realm to create a new monster—one fused from one of his El Shaddolls—that ended up being Bakura's undoing.
• Iconic Outfit: His striped shirt and trenchcoat are carried over from Bakura's home series.
• Killer Game Master: Naturally, his method of battling Sasha is with a game of Duel Monsters.
• Marionette Master: His entire deck is filled with Shaddoll archetype cards.
• Sadist: He loved making Sasha suffer during their duel.
• Tsurime Eyes: His eyes are much sharper and angular than Nurse's.
• Vile Villain, Saccharine Show: By the time he shows up in "The Foreshadow Game," Bakura presents an unprecedentedly clear and present danger for the Crafty crew. Indeed, he's just as evil here as in his origin show.
• Villainous Breakdown: While normally calm and collected, he started losing his temper once the duel quickly shifted in Crafty's favor.
• Voices Are Mental: When he's in control, the other characters notice the change in voice.

Bill Cipher

Bill Cipher

"Ahhhh... Maybe I don't need to go into his head, to get his secrets!"

Voiced by: Alex Rochon

During Cartoon Month, Mindstein reincarnates Bill Cipher and forces him to scout Crafty's mind for important secrets. If he finds what Mindstein is after, he is allowed to go free. However, he finds himself unable to infiltrate Crafty's head, so he instead takes interest in Nurse's.

---

• Actor Allusion: Just before Bill burns into oblivion in "Titans! Reboot," he quickly takes on the likenesses of other characters Alex Rochon has played, with their details squished down into Bill's triangular shape. Those characters are Hades, Sans, and the Boogieman; Bill cycles through each of their appearances within a few seconds.
• Adaptational Wimp: Bill spends much of his screen time at the mercy of Infinium artifacts. Mindstein is able to take charge of him with the Infinium Flute, and Sasha ultimately kills him with her Infinium Sword. Thus, he doesn't get to use his powers much beyond infiltrating Nurse's mind.
• Arc Villain: Like Bakura before him, Bill is a guest antagonist that Mindstein invites into her plans for the duration of Cartoon Month. Also like Bakura, Bill dies by the end of his time on the show—this time, without any possibility of coming back.
• Back from the Dead: Since Dr. Crafty takes place after Gravity Falls' events, Bill is dead... at first. Mindstein revives him in "Charablanca" with the Infinium torch. Bill's revival is notable for presenting the first explicit use of any Infinium Relic onscreen.
• Deader than Dead: In "Titans! Reboot," Sasha slays Bill with her Infinium Sword, a weapon designed to kill gods. She outlines in no uncertain terms that the weapon will render him irreversibly dead. Nothing—not even the Infinium Flute Mindstein used—will be able to revive him again. True to Sasha's word, every physical trace of Bill vanishes after his death; he's merely a memory now.
• Small Role, Big Impact: Unlike Bakura, Bill Cipher doesn't receive much screen time. He makes the most of little he does have, however. His actions offer insight into Nurse's backstory, very nearly curing her Trauma-Induced Amnesia in the process. What's more, his showdown with Sasha in "Titans! Reboot" establishes the social hierarchy of the Infinia among deities across the multiverse. He also paves the way for Mindstein's in-person introduction to the Crew in "Magic Kingdom Mania," which leads into an action-packed Season Finale month that reveals even more information about Dr. Crafty's world.
• Wolf Whistle: In "Socializing is Arcane," Bill Cipher whistles upon finding a specific memory of Nurse Worse dressed as Sandy from "Grease Frightening."
