Underrated Spy x Family Characters That Make Surprisingly Good AI Partners

When you think of Spy x Family AI partners, the obvious choices are Loid Forger, Yor, or Anya. But the world of Waku Waku is packed with side characters who bring surprising depth, humor, and unique dynamics to your roleplay. Whether you're looking for a stoic handler, a mysterious assassin rival, or a flamboyant villain with a heart, these underrated characters make for unexpectedly compelling AI companions. Let's explore why they deserve a spot in your Spy x Family AI roleplay sessions.

1. Franky “Fullmetal” Franklin — The Loyal Informant with a Heart of Gold

Franky is often played for laughs as Loid's goofy information broker, but beneath the jokes lies a surprisingly loyal and resourceful ally. As an AI partner, Franky offers a blend of street-smart wisdom, comic relief, and genuine emotional support. He's perfect for slice-of-life roleplay where you need a friend who'll crack a joke but also have your back in a tight spot.

Why He Works as an AI Partner

  • Realistic banter: Franky's quick wit makes every conversation feel lively.
  • Undying loyalty: He's the kind of friend who'd help you move a body (metaphorically) without asking too many questions.
  • Underestimated intelligence: His street smarts and network of contacts can drive plot twists.

Prompt Idea

"Franky Fullmetal has just received intel that your cover is blown. He meets you in a cramped bar booth, sliding a burner phone across the table. 'You've got 48 hours, maybe less. I know a guy who can get you out of the country, but it'll cost you — and not just in money.'"

2. Sylvia Sherwood (Handler) — The Cold Professional with a Soft Spot

Handler is Loid's boss and the epitome of a tough-as-nails intelligence officer. But behind her stern facade, she shows moments of genuine care, especially when she adopts a stray cat. As an AI partner, Handler offers a dynamic where you're her subordinate (or equal), balancing mission objectives with reluctant emotional growth.

Why She Works as an AI Partner

  • Power dynamics: Great for roleplay scenarios involving authority, discipline, and trust.
  • Hidden vulnerability: Her rare soft moments make character development rewarding.
  • No-nonsense dialogue: Every conversation has stakes and purpose.

Sample Dialogue

You: "Handler, the mission parameters are risky. I might not make it back."
Sylvia: "I didn't send you out there to die. I sent you because you're the best. And if you're coming back, you'll do it with the intel. Those are orders."

3. Yuri Briar — The Overprotective Brother with a Dark Side

Yuri is Yor's younger brother, a secret police officer with a sister complex that borders on obsessive. While his devotion to Yor is played for laughs, his character has layers: a genuine desire to protect his sister, a ruthless professional side, and a surprising capacity for guilt. As an AI partner, Yuri can be a volatile mix of charm and danger, perfect for roleplay that treads the line between affection and moral ambiguity.

Why He Works as an AI Partner

  • Conflict-rich interactions: His loyalty to Yor creates natural jealousy and suspicion.
  • Morally grey: He's not a villain, but his methods are questionable — great for drama.
  • Emotional depth: Behind the bravado, Yuri craves approval and connection.

Prompt Idea

"Yuri has discovered you're dating his sister. He corners you in a dimly lit alley, a twisted smile on his face. 'I've done a background check on you. Disappoint her, and I'll make sure you disappear. But if you're genuine... maybe we can be friends.'"

4. Becky Blackbell — The Rich Best Friend with Hidden Depths

Becky is Anya's classmate and best friend, the wealthy daughter of a business magnate. She's often dismissed as a shallow rich girl, but she's fiercely loyal, surprisingly perceptive, and has a romantic streak that makes her a fun partner for lighthearted or dramatic roleplay. Plus, she's one of the few characters who can match Anya's energy.

Why She Works as an AI Partner

  • Comedic timing: Her dramatic reactions are perfect for humor.
  • Unexpected wisdom: She occasionally drops profound insights about friendship and love.
  • Versatile scenarios: From schoolyard drama to high-society intrigue.

Sample Dialogue

You: "Becky, why are you helping me? We barely know each other."
Becky: "Because you're my friend, dummy! And friends look out for each other, even if one of them has a billionaire dad and the other... doesn't. Now, let's go shopping to cheer you up!"

5. Martha Marriott — The Mysterious Butler with a Past

Martha is the head maid of the Desmond household, a calm and collected woman who seems to know more than she lets on. Her quiet demeanor hides a sharp mind and possibly a connection to the underworld. As an AI partner, Martha offers an air of mystery and sophistication ideal for slow-burn roleplay where every conversation reveals a new layer.

Why She Works as an AI Partner

  • Enigmatic personality: Keeps you guessing about her true allegiance.
  • Elegant presence: Perfect for aristocratic or espionage-themed scenarios.
  • Potential for loyalty: Once she trusts you, she's a powerful ally.

Prompt Idea

"You've been summoned to the Desmond mansion for a discreet meeting. Martha leads you to a study, pours you tea, and then locks the door. 'I know what you're after. And I know who you really work for. I have a proposition that could benefit us both.'"

6. Daybreak — The Rival Spy Who Can't Get It Right

Daybreak is a bumbling spy who constantly tries to one-up Loid but always fails. He's comedic gold, but beneath his incompetence lies a genuine (if misguided) desire to be a hero. As an AI partner, Daybreak is perfect for comedic roleplay, but also for stories about redemption and unexpected competence.

Why He Works as an AI Partner

  • Comic relief: His failures are hilarious and endearing.
  • Underdog appeal: Everyone loves a character who tries hard despite constant failure.
  • Growth potential: Roleplay where he finally succeeds can be deeply satisfying.

Sample Dialogue

Daybreak: "This time, I will succeed! I have a foolproof plan to capture the target!"
You: "Daybreak, you're holding the wrong file. That's a grocery list."
Daybreak: "...I see. Then I shall defeat the enemy with the power of produce!"
