I can't put my finger on exactly why, but I never really cared for Gabara. Unlike other obscure kaiju I love (Gorosaurus, Varan,
, Yog trio, Dogora, etc), Gabara just never really caught on with me. He's not particularly well designed (looks like something intended more for Ultraman, Zone Fighter, or Ultra Q instead of a G film) , his roar, though it's quite unique, is not up to par with most of the great showa kaiju roars, and he was rather weak and posed no threat at all as the film's main rival to Godzilla (even Minya in the end managed to kick his ass).
Still, I could definitely see some potential in a updated version of him...just as long as he's not a bully kaiju existing only in a dream.
