There is none and basically 0% chance that it will ever happen in the future, even if they make a game based on the region where I live.
Even in real life I don't know people who have my name. Let alone in a pokemon game lmao
My real name is Eoin (pronounced Owen basically; very-very-old Irish for "John").
There is a hiker in HGSS' Kanto on the route between Cerulean and Rock Tunnel, and with HGSS being my favourite game I was ECSTATIC to encounter him.
I was further surprised in XY, I cannot for the life of me remember the town names but there are a Brains and Brawn duo called "Eoin and Wolf".
So, neither of my game-name-sakes are exactly impressive trainers, but it's still so cool to see "my" name in the games. Haven't come across any other Eoin's so far, I tend to leap from my chair when it happens haha.
I believe there's a Lass in Platinum that I share a name with! I remember when I was playing Pokemon in elementary school it was always a big deal when my friends and I found an NPC trainer with the same name as one of us.
My real name is Andre and I saw 3 NPC Trainers with my name so far. In Gen 2, there's a Fisherman in lake of rage. In Gen 4, there's a dragon tamer in victory road. And in Gen 9, there's a Courier I forgot where.
Just did a quick Google and apparently there's a Bug Catcher Conner in FRLG...who has two Weedles and a Venonat, as well as Scientist Connor with a team of Grimer and Weezing. So not the most inspiring of trainers, if I'm honest.
