Takahashi

Takahashi is the protectron proprietor of Power Noodles in Diamond City in Fallout 4.

Background
An unusual robotic chef, Takahashi has been operating Power Noodles at the center of Diamond City's market for fifteen years. He continuously stirs an unspecified substance in a stockpot. Takahashi is only able to say one thing, and according to a terminal in Mayor McDonough's office, this appears to be a malfunction. However, McDonough refuses to repair the robot because he believes it is a symbol of Diamond City's culture.

Before his time in Diamond City, Takahashi was just a normal protectron before somebody tampered with the robot's voice module and modified him to speak his single iconic line that is his only greeting and response.

Companion reactions
Several companions will interact with Takahashi in a small scene.
 * Takahashi will speak briefly with Codsworth if he is the companion. Codsworth appears to know how to speak to him. Codsworth seems to confirm the fact that Takahashi is broken, saying "Robco is no General Atomics, but I'm sure you'll find someone to fix you up."
 * John Hancock will ask Takahashi about the menu. He will respond with his usual greeting, after which Hancock will remark that "either this guy is busted, or I took way, way too much."
 * Curie will ask Takahashi about the menu. When he responds with his usual greeting, she will introduce herself to him in Japanese, saying "Watashi wa Curie desu" (私はキュリーです), which means "I am Curie." After Takahashi responds again with the same greeting, she will remark, "You know, I think this robot is broken."
 * Preston Garvey will speak with Takahashi if he is the companion, thinking that he is the bartender. However, Takahashi responds constantly with "Nan-ni shimasu-ka?" as he can't understand any words but 'yes.'
 * If Paladin Danse is with the Sole Survivor, he will respond hostile towards Takahashi and treat him as a "Chinese spy" even though he speaks Japanese. However, Danse will not cause any harm to him but swears that he will keep his eyes on him.
 * If Piper Wright is with the Sole Survivor, she will jokingly say that Takahashi is an informant and will then proceed to have a "conversation" with him. After asking Piper "Nan-ni shimasu-ka?" multiple times, Piper will respond with a sarcastic "no," and "I can't believe it." She will then speak to the player character, saying "Alright the jig is up. Takahashi told me everything. I bet your name isn't even really Blue..."
 * If Nick Valentine is with the Sole Survivor, he checks in with Takahashi, making sure no one is messing with him.
 * If MacCready is with the Sole Survivor he will accept some noodles and then enthusiastically ask for seconds.
 * Strong also has a dialogue with Takahashi, where he wonders about the open nature of the restaurant and also notes that Takahashi is broken and wonders why humans would keep a broken robot. However, this will never trigger correctly but it can still be heard by extracting the game's audio files.
 * Cait will ask Takahashi for a drink and will get progressively angry at him after he replies his only sentence each time she asks, finally calling him a "stupid robot" before giving up.
 * Deacon pretends to carry on a conversation with Takahashi, ending by telling the robot to "stay you."
