Galactus, the Devourer. Black Panther: Man Without Fear. Savage Dragon. For Better or Worse.
Some comics "need" to be read from the first issue of the story/run/comic to the end, to work their magic. What those are, depends on you. Maybe the single issues/stories don't fully introduce a plot each time or the characters. There could be a big reversal that's being built to. Satire can seem serious if it's just a short peek at it through a slender window.
A number of fans will say Morrison's Batman stuff needs to be read apiece, starting with Batman and Son (or starting with a lot of earlier prep work), and I can't say they're wrong, just that I don't think so. I think Batman Inc reads just fine on its lonesome. But, Happy!? If I'd tried to read Happy! while it was coming out, just the first issue, I probably wouldn't bother with issue two. The preview pages were too cranky for me, especially just then, that year, that time.
But, the collection had a clearly bigger game going on. I wouldn't have to sit for a month being depressed and scared or w'ev, I could move forward and forward, and the nastiness became more parodic, more clearly "hard" instead of hard, and I knew things were going to be alright.
