King Gojulus

King Gajuras (キング・ガジュラス) is the miniboss of Slash Man's stage in Mega Man 7. He is a giant Tyrannosaurus rex robot monster who chases Mega Man over many spike pits before confronting him. He breathes fire out of his mouth and fires a spreadshot from the cannon on his abdomen. He can only be damaged in his yellow jaws. The easiest way to defeat him is to stand on the ledge near to the end of the arenea & blast him with the buster. Another efficient method is to stand on the lower platform and activate Junk Shield twice and he'll crumble.

Trivia

 * It's possible that he was name after Godzilla, known as "Gojira" (ゴジラ) in Japan.
