According to their entries, Captain Klep (originally from Dave Angus, Nick Landau, and personal favorite Kevin O'Neill) only appeared in 4 issues of Tornado before it merged with 2000 AD.
I beg to differ -
It would be more accurate to say that the Captain appeared in all but 4 issues of Tornado. You'd still be wrong - but not by much. He was in, or rather - on the back cover of - all but 5 issues.
