Vicky the Viking is one of the main influences behind One Piece, a 70’s anime co-production based on stories by Runer Johnson. It was shown in the UK, at least in my region, when I was a kid, so it took me by surprise to learn it was a Japanese co-production when I saw it mentioned by Oda in a text piece in the One Piece manga a few years back. It’s one of the 60s-80s series that has gotten a box set DVD release in Japan in recent years. You can also get it on DVD through Universal in Germany, which is where it first aired.
Curiously there was a computer game released in english in 2002. I wonder if, as they are a Universal release, that the German DVDs have other language options on them?
