All-Star Superman # 10
Grant Morrison and Frank Quitely
Doesn’t this issue just fulfil all the potential of the character in one comic? With his death imminent, all Superman’s strengths come to the surface – in this one issue we find him noble, self-sacrificing, stoic, thoughtful, intelligent, forgiving and loving. All whilst looking for a cure, putting his affairs in order and carrying out his usual duties (rescuing a potential suicide, stopping a speeding train, battling a giant robot etc).
Writing and art of the highest standard.
A perfect superhero comic then.
