In the 1970s, Chris became a Marvel Comics junkie and a huge Spider-man groupie. He poured all of his energy and focus into becoming a comics professional. During the 1980s, Yambar established Manna Underground Press and published an international underground paper called The Activist - Radical Truth Through Art, Music And Social Commentary. In 1994 Yambar and Gary A. Smith founded Substance Comics. The little two- man company produced three 64-page issues of Substance Quarterly, but the science fiction and fantasy title died before its first birthday due to the national collapse of the comic book direct market distributor network that year.
The year 1994 also marked the birth of one of the most popular characters in independent comics. The character was created as a single panel gag cartoon by Yambar at The Beat Coffeehouse in Youngstown, Ohio. The character was then put on coffee mugs and T-shirts by Two Funn, a business Chris and ad specialist, Marianne Earnest, formed to take advantage of the exploding national interest in the coffeehouse scene. When Two Fun dissolved a few years later, Yambar regained his character rights, gave the little beatnik a name, a limited-edition ashcan comic, and took the show on the road. In early 1997 the first Moordam Comics issue of Mr. Beat Adventures hit comic shelves across America... and promptly sold out! It was a trend that he would have to get used to. In 2002 two new Yambar properties appeared. The first was 'Spells', the story of 3 little witch sisters which he co-created with artist Levi Krause. The second new bundle of joy is 'El Mucho Grande- Wrestler For Hire', created by Yambar, with art by Broderick and inks by Ken Wheaton.
