Found those two comic books, one if Goldorak (Grendizer) while the other is Capitaine Flam (Captain Future). These are based on probably my favourite TV shows as a kid.
UFO Robot Grendizer is a super robot TV anime and manga created by manga artist Go Nagai. It is the third entry in the Mazinger trilogy. It was broadcasted on Japanese television from October 5, 1975, to February 27, 1977, and lasted 74 episodes. The robot's first appearance in the United States was as a part of the Shogun Warriors line of super robot toys imported in the late 1970s by Mattel, then in Jim Terry's Force Five series, both under the title Grandizer. It is still widely popular in the Middle East, and it was especially popular in France and Quebec, as well as among French speaking Canadians where it was aired under the title Goldorak. In Italy, the series was as popular and known as Goldrake.
Captain Future is a science fictional hero pulp character originally published in self-titled American pulp magazines during the 1940s and early 50s. In 1978, one year after Hamilton's death, Toei Animation of Japan produced a Captain Future TV anime series of 53 episodes, based on 13 original Hamilton stories. Despite the strong cultural differences and the large gap between a literary work and animation, the series was close to the original in many ways, from the didactic scientific explanations to the emphasis on the usefulness of brains as opposed to brawn.
The series was translated in several languages and distributed globally. The four episodes comprising the series' second story arc were dubbed into English and released on video by ZIV International in the early 1980s as The Adventures of Captain Future. In the late 80s, Harmony Gold dubbed the series' initial four-part story as an edited "TV movie" simply entitled Captain Future.
