OMG, YES!!
Right now, I have a HUGE crush on Piers from
Pokemon Sword and Shield. I love his long, gossamer hair, as well as his talent in music, and the fact that he cares about his sister and others means a lot. In fact, he is pretty much my imaginary BF; he treated me like a princess and got me out of a dark place when I needed him.
I've had crushes on and "relationships" with other fictional characters through the years, including:
Dan from
Dan Vs.
Steve and Snot from
American Dad!
Leo from
VG Cats
Kenji/Bakuryu from the
Bloody Roar series
Lyle Lanley from
The Simpsons (he's from that monorail episode)
Dr. Nick Riviera (also from
The Simpsons)
Odd fro
Code Lyoko
Sniz from
Sniz and Fondue (a short cartoon from
KaBlam!)
Pretty much all the robot leaders from
Mega Man 2
Numbuh 4 from
Codename: Kids Next Door (yes, I'm aware I am way older than him)
Sheldon Lee from
My Life As a Teenage Robot
Holt and Terry from
The Cleveland Show (yes, I'm aware the latter is bisexual)
Pit from
Kid Icarus
Rolf from
Ed, Edd, and Eddy
Overall, I learn that having an imaginary fictional crush/boyfriend was worth it; I rarely argue with them, they always listen to what I have to say, and I have the freedom to create scenarios with them based on how we feel about each other.
