>>647605The Aquarion trilogy, Daikengo, Giant Gorg, Acrobunch, MD Geist 1 and 2, Claymore, Gravion, Godannar, Gun X Sword, VOTOMS, Dougram, Zegapain, Ryu Knight, Ideon Xabungle, and Mashin Hero Wataru. Normally I'd list way more, but you were specific.
And you know what? Just because I trust you I'll even recommend The Ultraman from 1979, one of my all time favorites and almost never recommend to other people (because having a show to yourself with few outsiders mocking it is always nice to have). The adventure portion is mostly in the last quarter, but if you want giant monster fighting it will not disappoint.
