Artist's CommentsAs said, Lopan is someone elses creation, and we never expected to make a go of this as a comic anyways. Just for our own amusement.
Anyway we couldn't just disappear him and disappoint our readers so we offed him, with no real explanation. Why he is dead takes time and materials and isn't really the message. He IS dead IS the message and could be told kind of funny like while introducing the new sidekick.
