Appearance[]

Fifteen is a poorly-drawn Arabic numeral fifteen. She has a dark-red body and limbs that are more lightly-colored.

A fusion of Nine and Six is also poorly-drawn Arabic numeral fifteen, whose body is the color of a white-blue gradient and the limbs are pale blue.

Personality[]

Fifteen seems to be quite aggressive, yelling at Nine and Six when they arrive to her home. When Nine and Six pose as Fifteen, she's greeted very excitedly by the other numbers (which they speculate as the reason for Fifteen's isolation).

Fifteen also has some violent tendencies, as shown in Thanks for 2,000,000 Subscribers, where she beats up Nine when they returned to get their sunglasses back, using a flamethrower on Nine when they attempted to retrieve their sunglasses again, and on Fourteen (when divided by Two) just for him even approaching her home (under the impression of getting free tasty skin).

Fifteen as a fusion of Six and Nine basically has no character. Their body is controlled by Six and Nine. They're able to talk inside. If fusion has a character, then it most likely combines or alternates Nine and Six's characterizations.

Powers and abilities[]

Most likely, both Fifteens have the same powers that are subject to any Algebralian.

Coverage[]

In "Thanks for 1,500,000 Subscribers!", Six and Nine are seen driving to Fifteen's Home. When they get there, they bang on her door until Fifteen furiously walks out telling them to leave, to which Nine bonks. Later, Six mentions that them and Nine would have to combine to make Fifteen. In the stinger, Fifteen, now with a black eye, picks up Nine's sunglasses, which they lost upon merging with Six. She smiles before the video ends.

In "Thanks for 2,000,000 Subscribers!" Green Seven is seen following many signs providing free skin. When he gets to Fifteen's house, Fifteen is seen with Nine's glasses again, a flamethrower, and a sign saying "right here" pointing to her. She then blows Green Seven on fire with her flamethrower.

In "Counting on Christmas", Fifteen is seen along with the other algebraliens singing about what they want. In Fifteen's case, she said that she wanted a new house in the forest.

She doesn't have a significant role in "Thanks for 2,763,000 Subscribers!", due to refusing to leave the cabin even after the broadcast, but she does make minor appearances in drawings in Zero's Base. Later, it's discovered through a tape previously thought to be destroyed that the capped Zero has a crush on Fifteen, after unknowingly being recorded hugging a pillow in bed.
