Meaning & Story

Named after Lion-O, the heroic leader of the ThunderCats, evoking courage, strength, and noble leadership.

Lion-o is a name pulled directly from 1980s cartoon royalty — the young lord of the ThunderCats whose bravery and heart made him one of animation's most beloved heroes. For a pet, it's a playfully heroic name that works especially well for large, majestic dogs with an undeniable presence. It signals an owner who grew up with the show and wants their pet to carry some of that same noble, adventurous spirit. A Lion-o is brave, loyal, and probably thinks he's the mane attraction.
