T

T is a gray Letter T. His eyes are located at the sides on top of his head and has a long mouth. In Number Lore, a back fin can be seen. He is based on a hammerhead shark and possibly an iron pickaxe. As a child, t was friendly towards many of the other Letters. One day, f and l got into a fight, and T was used by F, along with a and r, to make the word "fart". This embarrassed L, who along with O, made F along with R, I, C, and K spell the word "frick". Angered, T snuck under the ground and hit F in the back. Over time, T also grew as an adult. One day, F decided to get revenge on all the Letters.

In his titular episode, T, T was hammered into the ground by F. The Letters A, B, C, G, M, N, and P all watched T get hammered and fought F to try and stop him. During the battle, M's gem was sucked up by F, and F used the : gem to attach M and A to T.

After being stuck in the ground for a while, T watched the beam that was shot through F by N, along with B and W. Later, T also watches the sky as Z reverses time to undo what has happened. When he grew up in Number Lore, he emerged from the ground to notice a convoy (made up of the VAN, L, O, and the BIKE) chasing after the calculator ship. T almost got run over by the BIKE as he hid back in the ground before the BIKE ran him over. T followed the convoy to Z and watched the calculator ship perform an emergency landing before the numbers made 3.

In 4, when the VAN and L went to F's cave, T and the others watch from a distance. Once the Numbers broke free of O's gem, they form a train with the Math-Machine and run over T and the others.

In 5, T was nearly trampled by the BIKE while they and N were rescuing other letters from the horde of Fives. Initially enraged by the fact that this happened to him twice, he soon understands their intentions after noticing the horde and creates a sinkhole to Z's innards for his allies, closing it just in time before the horde arrives. T is a Letter who is very curious as he often pops out of the ground to observe what's going on around him. His curiosity has put him in dangerous situations, such as nearly getting run over by the BIKE and getting hit by 2. He may also be very good at architecture because he apparently made his entire home/bunker by himself.
