The pilot of Great Mazinger, Tetsuya Tsurugi is voiced by Toshihiko Seki (Duo Maxwell in Mobile Suit Gundam Wing), and his partner Jun Honoo, who is now having his baby, is played by Ami Koshimizu (Sailor Jupiter in Sailor Moon Crystal).
The official website for the upcoming new anime film Mazinger Z/Infinity confirmed today on October 10 that Tetsuya Tsurugi and Jun Honoo, the two main characters from the sequel series Great Mazinger, will appear in the story.
And of course the title robot Great Mazinger will form a tag-team with Mazinger Z once again.
