You've got your Johnvee and evolved him into Joltijohn and you're like well shit fuck this ground gym leader can't beat him. Gotta restart
But you wanna keep Joltijohn. So you trade Joltijohn to another game session.
You can now restart the old game. You still have Johnvee there to pick up again. He's the same but now he's different. He can live another life that's different from the original like turn him into Flarejohn.
You can also bring your old Joltijohn into your game too. You now how 2 Johns.
