These are not significant characters from fandom. They are every single character I could think of from anything beginning with the letter Y, which is barely even a real letter. In MY book. My book doesn't have words like 'my' in it.
Yosemite Sam - From Loony Toons. Bugs Bunny's arch enemy. Tiny and violent. I don't have much of a relationship with Yosemite Sam these days, but he was a not insignificant figure in the first four or so years of my life. I did quite enjoy those cartoons. They did a good line in compact fury.
Yorick - The jester/skull from Hamlet. Not the most interesting character in the play, but probably the second most famous.
Yellow Dog Dingo - I think technically he's just called 'Dingo', but the refrain goes 'Up jumped Dingo, Yellow Dog Dingo (always hungry, dusty in the sunshine etc.)', so he can count. He's out of the Just So Stories. The one about how the kangaroo got his legs. I used to know that story off by heart, it's so fantastically rhythmical, but I think I've mostly forgotten it now. ( Spoilers for the story of How the Kangaroo Got His Legs. I'm possibly a mite too careful about spoilers. )
Mr Younger - From the episode of Nightingales called 'Reach for the Sky'. ( Spoilers for the episode of Nightingales called 'Reach for the Sky'. )
Yoda - I don't care about Yoda. I can't abide Star Wars. What I like most about him is that his name begins with Y.

I'll give you letters if it's letters you want, but I have to warn you they might be pi.
