With his friends Koji and Hikaru (and later his younger sister Maria Grace), Duke decides to fight back using his best weapon – the almighty Grendizer.
First of all, I’m not as old as the anime, in Quebec it got aired for the first time in 1978 and got a couple of re-run after. That being said, I will not lie to you, the only thing I actually remember from this anime is the opening, which I still listen mostly when I feel a bit nostalgic.
I will still suggest you to watch it if you can get you hand on it.
