You've seen pictures of Link and Mario and Scribblenauts Unlimited and now you can see Nintendo's star characters in action in this pair of videos.
In the Zelda video, Maxwell is faced by Ganon so he summons a Hylian Shield and a Master Sword to take him out.
Then it's Mario's turn. He is flamed by Bowser but summons a Fire Flower and gives him a taste of his own medicine.
How cool is this?
