Do you ship Dextercup?
wow, ok can of worms incoming i apologize.
Generally speaking yes I do think they’d make a great pair. I have a whole bizarre fanfic that i sometimes write when i feel like it called The Ballad of Blossom Utonium (https://archiveofourown.org/works/10498830/chapters/23162352)
In it Dexter and Buttercup are a couple or at least were. In any case yes my main pairings when it comes to ppg
Aku x Blossom (dont ...dont ask friend dragged me down this path altho i go back and forth on whether i find it a healthy ship dynamic but its certainly an interesting one)
Dexter x Buttercup
Then I also ship Chusei (the daughter of Aku x Blossom who doesnt like either of them)
with a version of Daphne Blake from Scooby Doo thats a witch
and they fuse together into a being called Cherry Blake
Blossom x Mandy (from grim tales of billy and mandy) again ...its not really a romantic dynamic more like eh...kismesis like in homestuck.
More pertintent to your question in my head/metaverse/unwritten wip fanfics Dexter programmed an android utilizing the mental profiles and dna of both him and buttercup. His name is Dex, he’s cool, gotta remember to commission a pic of him.
Sorry for the long tangent just cartoon ships are a can of worms i can ramble about for years
