this is one great monster that took forever to be revived. a good story as well, and a great battle. Ultraman's spacium beam doesn't have any effect on Antlar, which is kind of cool. the Science Patrol helps defeat the monster.
the page on Wiki for Antlar is decent, but how can a monster made in 1966 borrow legs from Megalon, made in 7 years later in 1973? I know, it's like shooting dead fish to pick on Wiki, but really, what moron wrote that?
