Lakithunder

Lakithunder is the World 7 boss in New Super Mario Bros. It is a Lakitu with sunglasses who rides a dark cloud; it is a member of the Koopa Troop. As the name implies, it can shoot lightning directly under it, and also throw Spinies like the other Lakitus. The Spiny Eggs it drops bounce around erratically, unlike those of normal Lakitus. The player must jump on Lakithunder's head three times when it swoops down low in order to defeat it.

As World 7 is a secret world, Lakithunder is one of two bosses not encountered in the standard path through the game, along with Mega Goomba.
