From the Super Mario Wiki
Thunder Cloud is the Round 5 boss of Wario Blast: Featuring Bomberman!, formed out of the three Madbombers. It floats slowly around in any directions. It attacks by shooting lightnings in four different directions when Bomberman or Wario are directing near Thunder Cloud. In order to defeat it, Bomberman or Wario must lay bombs down near Thunder Cloud to have it get hit by the blast. After six hits, Thunder Cloud is defeated and the protagonist moves to the next stage.
