Robot King (Dub)

Three children pilots fight against the Dark Empire on their mission to destroy the universe. This film was edited with footage from Savior of the Earth, Defenders of Space - Phoenix-bot Phoenix King, King Robot, Protectors of Universe - Super Express Mazinger 7, Solar Adventure, Space Transformers - Micro-Commando Diatron-5, Super Mazinger 3 and Iron Man Trio. All the aforementioned movies also ripoff other anime like Mazinger Z (and all but the last were separately dubbed by Joseph Lai as well). (Source: IMDB, Tropedia (edited))
