He is also the secondary antagonist of the film.
Malness was an assassin from the country of Selgina, dispatched to Japan to murder Princess Selina Salno and obtain the golden bracelet of succession from Salno's uncle. His efforts were thwarted both by Detective Shindo and by repeated attacks upon the country by Godzilla and Rodan. Eventually Malness and his henchmen trailed Selina to Dr. Tsukamoto's clinic. Fended off once more by Shindo, the assassins attempted to pursue them into the hills, but a stray blast from King Ghidorah buried their car in a landslide. Malness survived and chased Selina and Shindo on foot, but his attempt to snipe the Princess was accidentally thwarted when another blast from Ghidorah killed the assassin.
