You've heard of OTPs and NoTPs, now get ready for...
WOAH-TPs, pairings you never considered but now ship.
Clawhouser/Gideon (Zootopia) - Clawhouser likes cakes, pastries, and sweets. Gideon is a baker. They might live in different cities, but they have a friend in common in Judy. Gideon could bring her some baked good one day, which she would obviously share with everyone at the precent, and it would be “love at first bite” for Clawhouser. OR, Gideon could move to Zootopia and open up a bakery not far from the precent. Clawhouser would become a regular customer and it could be a really cute “Bakery AU” type slow burn.
Trunks Briefs/Chibiusa (DBZ-Sailor Moon crossover) - This was a Woah-TP for me before it became my OTP. Mirai Trunks and Chibiusa are both the children of royalty, who come from broken dystopian futures, they travel back in time to dave their parents and hope to save their own time. (Also, Daddy Issues.) They have so much in common, its a very strong foundation to build a relationship on. As for the age difference between them, that can easily be reconciled by their time travel.
