El Gordo and Nate the Dragon are two army specialists that once joined up with the Terrible Thunderlizards and Mr. T-Rex to form The magnificent five-and-a-half. El Gordo is a master of disguise (he is 'invisible' when standing behind a flower) and Nate is a martial arts experts. Neither of them were very memorable and they only appeared in one episode I know of, so this is all I know about them
