>>46944781My 'Pokemon fusion' pitch is, instead of autistic deviantart-tier hybrids, it's based around the idea of different Pokemon species forming a symbiotic relationship that causes them to 'fusion evolve' into something new
This already kinda exists in the form of Shellder+Slowpoke and Mantyke+Remoraid, you could just expand the concept to include a bunch of new ones
It fits Pokemon's fantasy ecosystem much better I think
