Its weird when people say “Grant Morrison just creates things no one else uses” and over at we got Damian Wayne, his version of Frankenstein, Animal Man (yeah, he didn’t create him but c’mon-Morrisons first major US work and first hit? Morrison did create his children though), now Graysons going to use Spyral, Calvin Harris/Superman showing up in Earth 2 and the third weekly series.
Morrison practically stuck to X-Men at Marvel and Fantomex is still a cult character.
These are all small examples and I know I’m missing things. I guess a more accurate criticism would be “Morrison creates too much for other creators to use.”
