Today's dojo update is a pretty good one, as we not only get shown a new Pokemon that has a pretty unique skill, but also get another installment in Iwata Asks, where the Nintendo president not only apologizes for the Smash Bros. delay, but also talks about some other stuff.

Manaphy has a unique ability where it will swap the hearts of two combatants. What this does is cause them to switch bodies, essentially changing your character should you get caught in Manaphy's ability. For example, you can see Zelda and DK switching bodies here.
