Jungle Action Primer
Series Overview
Jungle Action was another jungle adventure anthology series that lasted for six issues. Regular features in this series were Lo-Zar the Jungle Lord, Man-oo the Mighty gorilla, Jungle Boy, and Leopard Girl. None of these characters really picked up and for the most part were never seen again.
When the series was revived in the 1970s the Lo-Zar stories were reprinted, but the character’s named was changed to Tharn and his hair was coloured red instead of blonde. Outside of this, Man-oo had a profile featured in the Marvel Pets Handbook and Leopard Girl was seen in Ant-Man: Last Days. So it seems incredibly likely that Lo-Zar and Jungle Boy are part of the Marvel Universe as well.
