Lakithunder

Lakithunder is the World 7 boss in New Super Mario Bros.. He is a Lakitu with sunglasses and a dark cloud. As the name implies, he can shoot lightning directly under him and throw Spinies. Mario must Jump on Lakithunder's head three times when he swoops down low to defeat him. It is unsure whether he was the one that caused the attack on Peach's Castle in the opening intro.
