One

Who is One?
One is a male number and member of the Number Squad. He first appeared in The First Episode where he is shown talking to Three about how nice the sky looks. He is her best friend.

Appearance
One is a dark blue number with neutral blue limbs and lavender eyes. He is one of the two taller members of the Number Squad, the other being Seven. Compared to the One from BFB, this version of him has arms.

Personality
One is considered to be a sneaky boy. He often takes things that aren’t his, even if they are valuable and very expensive. He speaks with a gruff voice, and is also a genius. One always gets away with his crimes, and never receives any punishment for what he does.

Despite this, he has a softer side to his personality. One doesn’t cry in the series, except for a few instances where those who get their things taken from them take One’s possessions away from him just to teach him a lesson.

He’s also much more wiser than his friend Three. He tells Three that she can’t judge anyone based on their covers. This refers to the first episode of BFDIA where Lollipop tells Book “I guess people judged you by your cover”.

Relationships
One is friends with every member of the Number Squad. This includes his friend Three. The two of them are seen hanging out together all the time. With Four, however, this is the opposite. He’s sometimes seen mocking Four for crying all the time. He gets reprimanded by X anytime he laughs at someone.
