HELP WANTED! Creating MS Paint Friendly Pictures, Deciding on a Character, & Guess Who...

Apologies once again readers...

As any of you are aware, I'm not pleased with my cover art for my story, Pokémon - The Equestrian Chronicles, I ask for your help on making MS Paint friendly pictures of Pokemon, Mega Evolutions, and Pokemon Trainers. On my DeviantArt account, I've posted several examples that give you an idea of what I'm asking you guys for.

Here's a link that has all of the pictures I made: http://poke-sonic-zillasaur.deviantart.com/gallery/55637445/MS-Paint-Pokemon-and-Trainers

It also includes a little tutorial on how I specifically do it...

If many of you read the previous chapter, you saw Xerneas say that Ash Ketchum was his trainer, and that Ash was with Serena, with this knowledge comes these questions to you readers from me, that you might even influence the story:

First, I'm pretty sure all of you are thinking, "LeBoché!!?? Seriously!? That's the best last name you got for Serena!?"
Yeah, I thought of a French sounding name to basically substitute until a better one is given or thought up, so...

Do any of you readers know of any good French last names to replace 'LeBoché'?

Second, to confirm your suspicions, yes, Ash Ketchum like from the anime. But, it isn't the same Ash we all know and groan at when he doesn't hook up with a girl, (Hopes for Amourshipping to succeed where all other ships failed...)...

But, how is he different, you may ask? Well I can't reveal that yet, but one piece of it is that he is a far more talented trainer, by having more pokemon, and parts of his character from the anime remain the same, but he's not the Ash we know...And what is this about Ash having more pokemon?

Well, what my version of Ash has that the anime's Ash doesn't have, besides Xerneas, are these few of the following;
A Lucario...
Two Eeveelutions...
A Durant...
A Togekiss...
A Tyrantrum...
...and...
An Arcanine...

Also, he has every Pokemon his anime counterpart has, official or unofficial, and some are at their final evolutions, except for a few, like Pikachu...

Here's where you guys can influence a part of the story;

Name each and every pokemon within the limits below that you believe Ash should've had, or should have in the future...

These are my limits to your choices;

1-Name within a certain number every regional pokemon, for example; Nidoking from Kanto, but each regional choice includes cross-generation evolutions, example, Electabuzz ->Electivire from Kanto...

2-The number of pokemon per region depends on the available pokemon per region; Kanto->5, Johto->3, Hoenn->3, Sinnoh->4, Unova->5, Kalos->3, and only two reigons can have the same type per type...

3-Your choice cannot be or have Legendary Pokemon from any generation, no matter how fitting the choice is...

4-They cannot be the same species of Pokemon owned by one traveling companion only, but can be an evolution of that companion's pokemon...

5-The pokemon can use any move they are able to learn legitimately from any generation...
&
6-Starter Pokemon not owned by Ash are allowed...

I hope you'll help me, and...
I eagerly await your answers...

Until next time...
Bye...
