Would egg theft be something rockets would be interested in as well? Riku is one of the folks running Kanto's breeding center, so he could theoretically have a few eggs stashed in the PC with some egg moves that could either be hatched and trained for rocket purposes or resold on the black market?

I'd consider actual mons to steal, but I haven't updated his roster in ages.

Either way, he's in Kanto.

Late to the party because I've been a busy bee. RETAIL, man.
