P

P is a pink Letter P. Her eyes and mouth are located on top of her head and has 2 curly eyelashes on each eye. In her superhero form, she gains muscles and reflective pink eyes. When obtaining the ! gem, she becomes very fast. She appeared to have some sort of attraction for G, as she was constantly kissing him as a lowercase Letter. After F ran next to them and cried out the ! gem, P received it. Sometime between F's departure and eventual F's return, P grew into an adult.

In her titular episode, P, P introduces herself. And before she does a sailor moon esc. transformation, P looks at G, making him blush, with P also blushing.

In R, after L and O fly away due to N losing his gem, P helps him up and transforms back. She bangs on "CAB" and creates "MAP" to help the Letters track F down.

In T, they reach F, but F freezes G using L's gem he had stolen.

In U, N hides behind G, while M, A and P deform, determined to beat F. M attacks unsuccessfully, and F uses O's gem to connect M and A to a stuck T. P then does a sailor moon esc. transformation. She then bolts around F, successfully. F then tries to use M's gem to slow P down, but she pushes him. Unfortunately, as she tries to charge a laser beam, F uses M's gem and slows her down. After F kills C and makes B immobile, F bites P, ripping her head, and flies away with her, freeing every Letter.

In V, V notices P (being mistaken for F) about to attack him, which startles him. However, "GUN" shoots unknowingly at P as she approaches V. P ends up being immobile, and the Letters mourn her death.

However, in Now I Know My ABCs, N hugged P and cried out the '!' gem out of joy as he was so emotional. In the new timeline, P is now a mother raising a son, and likely married to G. When their baby gets accidentally taken by VAN, P grabs her "!" gem to power up so she can chase the convoy and save her son. She successfully saves her child after he was thrown in the air by 3, but then 3 uses his tongue to grab her, and proceeds to swallow and poop her out in a yellow, transparent cube.

In 4, G calls for P in morse code after he gets run over by the numbers, and they set off to save g, but struggle due to bouncing in the wrong direction. At the end of the episode, they watch in shock as the Calculator Ship flies to Planet 0 with F, L, and g.

In 5, P and G chase the Numbers around F's cave, and 4 makes a thornball to protect the numbers and herself from P and G. They attack the thornball several times, but to no avail. After the 3rd time, they miss, but hit the cave that bounces the thornball very high. After 5 was made, as a result, P and G destroyed the equation machine and killed 1's clone as the latter protected his real counterpart with his pack. The numbers all stare at G, to which he pokes 5, but 5 severely smashes G into F's cave as E and I wonder what noise that was. P is shocked at what 5 did to G, and comforts the latter in his final moments. Angered by her husband's death, she angrily breaks free from her cube and attempts to charge at 5 in retaliation, only to be launched into outer space, dropping her gem in the process. P is a very friendly and supportive letter towards her friends, especially her boyfriend (husband in the new timeline) G and N, who views her like an idol. She cares deeply for her husband G and their son. P is also protective of her allies.
