[@1Charak2] [@Pink Madness] Just wanted to clarify something real quick. I'm gonna be making points in the plot where you will meet your Legendary Partner, you're not going to start out with them right away. This will be worked into the story for sure.

Another thing about your partner, I'll leave it as simple as I can put it: "They are "Immune" to Pokeballs". That is to say, you cannot capture them in Pokeballs, nor carry them around in one or such.

They do not count as one of your party members, so you can still have your standard six Pokemon plus the Legendary you chose.

Definitely limit the amount of battles you put your Legendary through, I would only use them if it was absolutely necessary to.

As you bond with your Legendary, both you and it will unlock hidden powers within you. They can be as slight as a Speed Boost from Shaymin, to advanced swordsmanship from Keldeo, and even a power boost from Victini. These will be slight at the beginning, but you will learn to control them. The earliest skill you can learn is Telepathy with your partner. This will awaken very quickly, within the first day or two of your bond.

Speaking of abilities, don't over abuse them. As with battling with your Legendary, I would save your abilities for the most dire of situations. There can be "accidents" of these abilities over time, since you would have only recently learned them, but keep it toned down a bit.
