Does it not? Reshiram created Unova. It gave the land life, created all of its beauty...

And now it stands with me, against what has happened to the land it birthed. I have heard the cries of the Pokemon, I have seen their scars and felt their fear. I know what humankind has done to them. Will continue doing to them if they are not stopped.

The Pokemon cannot defend themselves against humankind, so I will.
