Oshawott (the only change I make to ash's Oshawott is its personally. Instead of being a piplup clone, Oshawott is competent figher but has a quirk of being overcommitted. He tries his best to win a battle and show off at the same time, reacting with shock is he fails)
Tepig-Pignite (nothing much I change about this guy)
Snivy-Servine-Serperior (the only change I make with ash's Snivy is that she fully evolves to Serperior. When she evolves into Servine and Serperior I'm not too sure)
Rufflet-Braviary (the first big change in ash's unova team. Ash gets an egg from a daycare that hatchs into a battle hungry Rufflet that's pretty strong for its size and has a quirk of popping out of its pokeball like Misty's Psyduck. It evolves into Braviary during a gym battle against Skyla as ash's last pokemon)
Venipede-Whirlipede-Scolipede (another big change to ash's unova team. In the episode: a venipede stampede-ash and friends help an injured venipede, instead of joining back with the rest of the venipedes, the venipede ash helped decides to join his team. Not sure when it evolves into Whirlipede and Scolipede though)
Krokorok-Krookodile (really the only change with this guy is giving more battle wins and part take in more battles in general)
