I love this series. It's hilarious. It's serious. Gawl is generator from the future who has come back with two of his friends to prevent scientists from discovering generators, and thus begin the third world war. The dynamic between Gawl, Ryo and Koji is fabulous. The English dub is VERY GOOD. One of only about three anime I watch in English. Only down side to Generator Gawl is that it isn't longer. In the words of Koji: I'm giddy.
