Captain kangaroo, mister roger's, who was the other one I cannot remember? He had the blue coat???

we had a discussion about childhood shows we used to watch and I remember Captain Kangaroo had a rival on another channel, he was the mean version of the Captain and I for the life of me cannot remember his name. It wasn't Mr. Rogers, or Howdy Doody, can anyone help me? Just for reference I'm 39.
