Maskman is one of the hottest shows that I follow when I'm still a kid and just when I'm browsing YouTube for those retro animes I stumbled the show and found a great demand for Maskman episodes. It's hard to find one in YouTube but the good thing is that I discovered all of the episodes with the help of Google and intensive research.
It turns out that Veoh got the whole episodes on it's archive with a special bonus of it's movies! Anyway here's the link of the episodes http://bit.ly/KM0L5e and enjoy every bit of it! :) And before I forget if you're seeing only 5 mins of the video then you probably need to download veoh web player to watch the full clips.
