Job 1
Eevee and Riolu
Being playable Starters in the past, as well as maintaining high popularity, these two feel like shoe ins for the role of a Starter Pokemon.
Job 2
Partner 1 genuinely believes in doing good things for the world and helping as many as possible but will take any path or method to get to that point, no matter the sacrifice or what they would need to go through. They would do anything for the greater good like this, and often come into the conflict with the rest of the group for this attitude. They genuinely care though, and often follow along and help the other two members of the group as the more mature person there. Often being levelheaded in not so good situations. They'll try to save anyone, but if there's a risk that saving one isn't worth it compared to a greater benefit, they'll sit it out. They'd probably end up changing this to being more caring to the individuals and not the overall group by the end of the story.
Partner 2 would be happy go lucky. They're full of energy and always itching to move and explore. They understand how the world works and are truly smart on the inside, but they don't tend to use that often, instead opting for a more reckless approach because they find it more fun. They always stay positive and find the best in every situation, trying to turn anything into fun. They often butt heads with others who try to be more careful in their surroundings. They're basically the definition of hyperactive, constantly running and never running out of fuel until they tire themselves out. They tend to trip over things often in a rush before moving on like nothing happened. They'd probably end up changing to being cooler and more collected by the end of the story whilst still keeping the same have fun with everything attitude.
