**One**, more commonly known as **One-One**, is the deuteragonist of Book One and the robotic companion of Tulip who is trying to help her find a way back home. One-One can split into two halves, each with its own personality. The two halves are called **Sad-One** and **Glad-One** by the production staff, but as a single unit, they are called One-One. One-One is also the true conductor of the Infinity Train, and regains his position at the end of Book One.

## Appearance

One-One is a white, spherical robot with a black stripe that runs down the entire circumference of its body. On the front, the black stripe has two white dots that appear to be Sad-One and Glad-One's eyes when they are fused. One-One has four retractable spider-like legs.

The body can easily separate into two identical and independent parts and can reattach itself together again. Each half is hemi-spherical in shape with a black line at their base with a single white dot, their eye. The flat base of each half has four spider-like legs, similar in structure to when it was whole.

## Personality

As One-One is a twin single robot composed of two independent parts, it has two separate personalities. As a single unit, One-One often flickers between the two different personalities.

### Sad-One

Sad-One, the sad half of One-One, is morbidly pessimistic, practically always having a monotone voice and acting very downcast no matter the situation. Sad-One is almost always in a state of despondency, often shooting down any hopeful remarks. Though Sad-One is always pessimistic, it will sometimes drop pearls of wisdom that, ironically, encourages people.

### Glad-One

Glad-One, the glad half of One-One, is cloyingly optimistic. It has a strong sense of happiness, never speaking in a voice that is not overjoyed. Glad-One never deviates from his happiness and will always see life in the most optimistic way possible. Glad-One is also very naive, to the point of doing things with reckless abandon. Its naiveté, mixed with its strong sense of optimism, makes Glad-One have a strong lack of self-preservation.

### Merged

At certain times of stress and guilt, Sad-One and Glad-One's personalities can merge into a single 'identity', where both sides would talk at the same time. It is revealed in Book Four and hinted in Book Three that this identity was how he originally was before Amelia took over, to which he would be called One instead of One-One. As seen in the episode "The Unfinished Car" and in Book Four, One was more apathetic and cold than who he is now, being more focused on what he believes he is supposed to do without any signs of empathy.

### Conductor One

Many years prior to the events of the series, One was created by an unknown force to operate a train as its Conductor. As the Conductor, One's purpose was to create train cars and maintain them, in order to help passengers as they worked through their issues.

## Trivia

* According to Tulip, One-One has been on the Infinity Train its whole life.
* In the short "The Snow Car" Glad-One claims to have been stuck in there for thirty-three years.
* According to Owen and Maddie, One-One is the same size as an orb.
* One-One's two personalities share similar traits with Wheatley from *Portal* and Marvin from *The Hitchhiker's Guide to the Galaxy*. Owen Dennis has described his voice for Sad-One as a "bad Alan Rickman as Marvin impression."
* One-One's design was inspired by robots from sci-fi series such as *Star Wars*.
* Another reference to One-One being the true conductor of the train is shown in the actual logo of the show, as the infinity symbol can be interpreted as the two halves of One-One.
* "One-One" can be construed as the binary number "11", which corresponds to the decimal number 3.
	+ Sad-One and Glad-One are also each defined by their negativity and positivity, respectively; as such, they could be regarded as "negative One" and "positive One," which combined as numbers equals 0, the goal for passengers' own numbers.
* Sad-One is left-handed. This has correlation with many popular medieval beliefs that the left hand is the hand of deviance, sadness, and destruction. The right hand is seen as being the hand of happiness and prosperity, (hence the positivity with the word, "right," in the English language).

### Other References

* One-One makes an appearance in the background of one of the shorts in Cartoon Network's miniseries *Villainous*.
* One-One is one of many heroes that got turned to stone in "Crossover Nexus", a crossover episode in the show *O.K. K.O.! Let's Be Heroes* that uses most of Cartoon Network's shows.
