Wario was casually driving on his worn out bike when he looked ahead to see the shiny DeLorean sparkling in front of him; he didn't seem to care that Doctor Emmett Brown and Marty McFly happen to be present with the futuristic looking time traveling car because all the fat greedy man wanted was to take it for a ride.
"Wahaheh; this looks like it will cost a lot of money!" Wario happily said to himself laughing upon getting off and then eating his bike for he somehow managed to sneak into the DeLorean and took off. "Time to make mega bucks!"
"Great Scott!" Doc Brown exclaimed in disbelief upon seeing the fat tub of lard get away with their time traveling vehicle. "That thief just hijacked our time machine!"
"Oh geeze this is heavy!" Marty exclaimed in disbelief with him clenching his fists. "Doc we gotta go after him!"
Wario laughed upon seeing Doc and Marty call for a taxi to chase him since he decided to mess with the controls of the car which of course sent the dumbass into a future where everything was a wreck which confused the muscular fatass since he had zero idea as to how he got himself into this until he realized that he time traveled.
