>>43297680The soft reboot started being a thing in Gen 5, that's why the anime was trash. Both Orange Islands and Johto had Ash's Kanto pokemon appear constantly, Hoenn had Brock and the Battle Frontier season in Kanto, and Sinnoh also had Brock, aipom (caught at the end of Gen 3) and a big chunk of Ash's old pokemon.
Plus, Team Rocket's Arbok and Weezing were released in Hoenn, while the rest of their pokemon except Dustox, Chimecho and Cacnea spanned both gen 3 and 4.
