Wario is slow but very power full he gose in to space to get his treasure and save Mona from Dr. Marc but first he must help Rosalina get the power stars back from Dr. Marc and Wario gets his treasure back along the way.
Dr. Marc is an evil genius with an IQ of 170 he steals Warios treasure and kidnaps Mona he also takes the power stars from Rosalina's observatory so he can use them to take over all the galaxys and space.
Waluigi appears where he often teams up with Wario to save the universe from being ruled by Dr. Marc, and to retrieve the Power Stars for Rosalina. As a playable character Waluigi can be found at the beginning of certain levels. Walk over to him and talk to him. He will then ask the player if he can jump in. Waluigi can jump higher and run faster than Wario, but is harder to stop but to play as him Wario must 1st find 25 power stars then Rosalina will give you a message saying a purple guy was looking for you.
Luma becomes Wario's guide and gives Wario the ability to do the spin attack. Luma can be controled by a 2nd player (if u have 2 Wii Remotes) and he works just like how the Co-Star Luma works in Super Mario Galaxy 2
With the DNA from Wario treasure Dr. Marc was able to create a evil clone of Wario. (which he named Dark Wario) Dark Wario is Dr. Marc right hand man he will protect and serve Dr. Marc at all costs
Wario has his ability to gain different abilities via eatting food. Here is the list of his abilities.
Food Needed To Transform
When Wario eats the pasta he will turn in to a spring which is able to let him jump higher, but is no longer able to run. Instead, he simply bounces around the level. Using this form, Wario is able to bounce very high to reach items hidden in the air. It also grants him the power to climb very steep inclines in a slinky-like fashion and he can use it to get to higher places. If Wario takes damage, touches water, or lands on a Launch Star or Sling Star, however, the form is lost.
When Wario eats the shrimp he will then swell up, filling his head with air, allowing him to slowly float upward he can use this to get to higher places. This show that Wario must have an allergic reaction to shrimp (this power-up has a time limit).
When Wario eats the potion he will turn Invisible which alows him to walk through metal fences and certain walls. (this power-up has a time limit).
When Wario eats the burger he will put on weight and become very obese then Wario can brake blocks that normal Wario couldn't do, walk under water and enemies bounce off his stomach. Fat Wario is very slow (slower then normal Wario) Wario gose back to normal by walking for awhile.
When Wario eats the ice cream his body turns into solid ice. While granted this form, any water or lava he touches freezes solid in the form of a hexagonal platform (which melts after a period of time if left unoccupied). This allows Wario to walk or skate across vast distances of water or lava with ease and safety. Ice Wario can also freeze water spouts and waterfalls, which usually grant him passage to higher areas (this power-up has a time limit).
When Wario eats the pumpkin he will turn in to a bat now he can he can fly to higher places To turn back into his normal self he must go into a patch of light or land in water. The patches of light become obstacles for Bat Wario, as he must avoid them when he does not wish to resume his adventure in his normal state.
When Wario eats a chilli he will comically start racing around with his pants on fire soon, the flames will spread across his entire body, making him essentially a living Fireball. In this state he can mealt certain blocks, mealt metal poles and enemies cach fire when they touch him. This can be cured by falling into water or just waiting until he burns out (this power-up has a time limit).
When Wario eats a rotten garlic he becomes Wario-Man which makes him invincible. Any enemy that comes in contact with Wario will get defeated. Wario-Man can also run faster then normal Wario (this power-up has a time limit).
