- Detective Pikachu: [singing while sobbing] I wanna be the very best, like no one ever was. To catch them is my real test, to train them is my cause.
- Lucy Stevens: Down by the docks. Rough part of town, not the sorta place you wanna visit alone at night.
- Tim Goodman: [trying to impress her] Well, I'm actually pretty good at being alone at night.
- Detective Pikachu: Have you ever talked to a woman before?
- Tim Goodman: I've talked to women before!
- Detective Pikachu: When was that, in the the birth canal?
- Detective Pikachu: Should I talk about the fact that your childhood bed is a Pikachu bed?
- Tim Goodman: It's a coincidence.
- Detective Pikachu: I've never been so flattered and creeped out at the same time.
- Detective Pikachu: Maybe she can tell us about the long-term psychological effects of being strapped to a baby seat... next to a bomb!
- Psyduck: Psyduck!
- Detective Pikachu: [from trailer]
- [Tim has a stapler in his hand, and he doesn't know Pikachu can talk]
- Detective Pikachu: Oh, geez.
- [climbing up the top of the drawers]
- Detective Pikachu: Here we go. I know you can't understand me; but put down the stapler, or *I* will electrocute *you*!
- [Tim drops the stapler in shock]
- Detective Pikachu: [to Psyduck, trying to rile him up] I hated rubbing your feet! I can never forgive my hands for what they've done!
- Detective Pikachu: Harry faked his own death... or someone else faked Harry's death... or Harry faked someone else's death. Wait, that last one doesn't work, does it?
- Detective Pikachu: I can't help but notice your childhood bed is a Pikachu bed.
- Tim Goodman: It's a coincidence.
- Detective Pikachu: I'm sorry, what? I couldn't hear you. I've never been so flattered and creeped out at the same time. Are you gonna turn me into a lampshade?
- Tim Goodman: I might!
- Tim Goodman: I don't need a Pokémon, period,
- Detective Pikachu: Then what about a world-class detective? Because if you wanna find your pops, I'm your best bet. We're gonna do this, you and me.
- Detective Pikachu: [from trailer] They try to talk to me all the time, but all they hear is "Pika-pika!"
- Tim Goodman: [to a person's girlfriend, asking if she can understand Pikachu speaking] You can hear him... right?
- Pikachu: [in his Pokemon voice] Pika-pika!
- Girlfriend: [to Pikachu] Yeah, pika-pika-pika! He's adorable!
- Detective Pikachu: [to the girlfriend] YOU'RE adorable!
- [pause, knowing that only Tim can understand him]
- Detective Pikachu: They can't understand me, kid.
- Tim Goodman: [exasperated, knowing that no one can understand Pikachu] Can no one else hear him?
- Detective Pikachu: [holds his finger out to Tim] Smell my finger.
- Tim Goodman: I will never smell your finger.
- Detective Pikachu: Coward.
- Howard Clifford: The transfer worked. My body is in the chair, but my mind is in Mewtwo.
- Tim Goodman: Howard?
- Howard Clifford: Well done Tim, you and Harry's Pikachu led me straight to Mewtwo.
- Tim Goodman: Mewtwo didn't cause the crash.
- Howard Clifford: All your father had to do was take the money and walk away, But he started asking questions. I had to stop him.
- Tim Goodman: You tried to kill him!
- Howard Clifford: I had no choice! He tracked the R* to the battles, then traced it back to Dr. Laurant, and then he and his Pikachu helped Mewtwo escape!
- Detective Pikachu: [when Tim finds him in his apartment] Aw, jeez. Here we go
- [Climbs on a dresser]
- Detective Pikachu: [Slowly] I know you can't understand me, but put down the stapler or I will electrocute you.
- Tim Goodman: [Drops stapler]
