these are my versions of the teams of protags and rivals, I'll start with Unova.
Has the same role, and does not evolve.
Has the same role, but evolves to be the love of Meloetta.
Ash found this egg on Route 1. It later hatched in Castelia City.
One of the Ducklett trio joins Ash, it evolves in battle against Roxie.
Same as before, though ends up making the finishing blow to Virgil, letting Ash continue to the finals, against Kotetsu.
Same as before, but Trip's Gurdurr and Ash's Boldore get mixed up during the Pokémon League, and trade, the two thus evolve.
Ash finds Cubchoo near Twist Mountain, in which it is being chased by Cryogonal, it ends up on Ash's team.
You know Iris.
Same old Axew.
Iris cathces this little cutie in the Desert Resort, and ends up evolving against Drayden's Flygon.
The one from the Deino ep joins her.
Yes, instead of Cilan, his brother takes over as the travelling friend.
Starts off with him, evolves against Cress (equivalant of the Cilan Chili ep)
You should all know Trip.
Same as original
Because of his Alder fanboyism.
Like before, but it evolves into Vanniluxe against Ash in the Sinnoh League.
Litwick appears earlier, but in a cameo. Lampent the same, Chandelure used against Ash.
Same, but seen to have evolved in the junior cup.
Same... But evolves with Ash's Boldore.
Basically replaces Tranquill.
Bianca's trade instead happens with Trip instead of Professor Juniper.
Mareep was first seen with Trip trying to catch it, but was disturbed by Ash and co. It later reappeared as an Ampharos, battling against Ash in the Pokémon League.
Same old ditzy Bianca

She is shown to have Eelektrik by Mistralton City, and Tynamo is shown in a flashback. Eelektross is confirmed.
Bianca meets one after Luke's Zorua plays with one.
She is shown to have one the first time they meet. It evolved by the time Ash reaches Iccirus City.
It was seen battling against Elesa, being taken out by Tynamo. It was shown to have evolved once at the Pokémon League, nearly defeating Kotetsu.
Tara is one of Ash's Rivals, and is obsessed with the past, as such, she studies Pokémon fossils and mythology. Also a very skilled trainer, coming victorious in most battles she participates.
Tirtouga was with her the first time she and Ash meet, which is in Nacrene City. The two battle, and Tara ends victorious. It evolved by the time of the Pokémon League.
Like Tirtouga, it was with Tara when she first met Ash. It evolved by the time of the Pokémon League.
She uses it against Ash in their second battle in the Lostlorn Forest. Which Tara won. It evolves then, and is evolved again by the time she appears in Opelucid City.

It was used against Ash in their battle at Lentimas Town. It came out victorious. It was shown to have evolved by the time Tara was seen at the Junior Cup.
You know Burgundy! But in my version, she actually wins.
Same, but wins against Chili.
She used Darumaka in the Castelia Don Tournament, other than that the same, but she wins against Trip.
She had it with her the first time she met Ash, and was very scared of battling, never battling. By the time she is seen in opelucid City though, it has evolved and while still fearfull of battling, does it quickly to have to stop battling.
She was using it against Chili when they first met, where it lost against Lillipup. It evolved once she first met Ash.
Chili and his brother both set out, and they compete over who is the best Pokémon Connoiseur.
Starts with it, and doesn't really do anything.
Starts off with him, evolves against Chili (equivalant of the Cilan Chili ep)
Cilan captures it in the same fashion as Ash would have as a Tympole. It evolves immediately after, and was shown evolved in Humilau City.
Yup, same old Georgia, though she has more wins against Iris.
She was seen with Ferroseed in the Ferroseed Research institute episode. It was shown to have evolved by the time she appeared in Opelucid City.
She was seen using Whirlipede against Iris when they met at Driftveil City, she said she caught one of the rampaging Venipede. I evolved into Scolipede by the time she was seen in Undella Town.
Georgia used Basculin briefly against Tara in the Driftveil PWT, not much else is known.
Like Iris, an aspiring Dragon Tamer. He is still much of a rookie and learns from Iris when they meet.
Deino is Kai's main Pokémon, and is often seen with him. The first time he and Iris meet in Iccirus City Deino battled against Axew, where it lost.
Kai was seen with Swablu in Opelucid City.It later evolved against Drayden's Altaria.
It was seen battling against Georgia's Beartic, and despite evolving into Whiscash, quickly lost.
