Anguirus

is a monster who first appeared in Toho's 1955 kaiju film Godzilla Raids Again. It is the second monster to appear in Toho kaiju films. Anguirus appeared only a year after Godzilla. Though being the first monster Godzilla ever fought, he has allied with Godzilla in several other films against more dangerous threats. WatchMojo.com listed Anguirus as #5 on their "Top 10 Godzilla Villains" list.
