CNN reports the sad news that Dave Cockrum passed away on Sunday at the age of 63 after a long battle with diabetes and related complications:
Cockrum and Wein added their own heroes to the comic and published “Giant-Size X-Men No. 1″ in 1975. Many signature characters Cockrum designed and co-created — such as Storm, Mystique, Nightcrawler and Colossus — went on to become part of the “X-Men” films starring Hugh Jackman and Halle Berry.
Cockrum received no movie royalties, said family friend Clifford Meth, who organized efforts to help Cockrum and his family during his protracted medical care.
“Dave saw the movie and he cried — not because he was bitter,” Meth said. “He cried because his characters were on screen and they were living.”
