He hasn't been there for a while.
Jaded already, the man lift his glaze to the high buildings of Goldenrod City with a sigh. He had left Johto several years ago to go back to his native region, Orre, and he never missed the huge concrete blocks of this modern city. He's born from the desert and always avoided big cities and large concentrations of people. After having left his land to get a house in the capital city of Johto, some years ago, he never stopped to wonder what could have convinced him to do so. Was he trying to escape to some bad memories?

His look darkens while he was recalling the intense memories who marked the few years he spent in this city, so far from his home. Maybe he went back for those heavy memories. Maybe he was trying to find back something important he lost in there, to recapture what he loved, to find back those strong feelings, being positive or negative, he only met in there, or maybe was he there to fight against his misses and forget them. To untie him from all of them once and for all.
But, in Goldenrod City, only remains those cold concrete buildings and a crowd of strangers.
The man's look left the high roofs to come back to the ground. With a raging kick, he made the dust fly away around him, and turned around, turning his back to the white city, walking to the Route 34. He needs to allow himself to unwind. Maybe a fight may help. He observed the people around, looking for a trainer to challenge.

Actually just noticed I made a mistake within the roleplay : I confused two of his Pokemon and used a Houndoom he was supposed to have left in the PC.... So, here's the team he actually is using for this roleplay :
Umbreon
Feraligatr
Absol
Flygon
Houndoom
Espeon (stolen by the grunts)
