Robert

Neutral B: Comedy
Robert says "Ha" every time B is pressed. And every time he goes "Ha" the word ha appears on the left or right side of him. Touching the ha will cause damage. He can go "Ha" up to 7 times.

Side B: Crawling
He just crawls. Causes damage.

Up B: Super Jump
Robert jumps upwards, if someone touches him during this they get hurt.

Down B: Control ‘Er
Robert sits and pulls out a controller. Anyone standing in front of him during this will be stunned. Robert can now move the opponent wherever with the control stick. Pressing A or B releases the opponent, damaging them. Of course, the time you have for moving your opponent is limited.

Final Smash: Vintage World
Not much has been said about this final smash, other than the fact that it will act similar to Luigi's Negative Zone.
