I was going to say there's not very many kantomons who haven't received a mega, z-move, gmax, regional form, cross-gen evo, or cross-gen pre-evo. And that it could actually be a coincidence.
But there's surprisingly a lot of fully evolved kantomons that are "unpandered". 17 of them, in fact.
Is a 1/17 guess impossible? No. But I also don't think it's likely.
