Titan Finale Planning

I do have a complete end vision for the Titan series. I know exactly how the saga of Michael Novak will end and most of the bumps in life he will experience until the time comes that he is no longer Titan. I have also thought of a secession plan for Titan to have after Michael. One of the intriguing aspects of superhero comics, at least today, is that so many of have been around for so many decades yet the characters have not aged in that time even a little. Okay, Spider-Man aged a little but not a whole lot. I plan to have Titan not only move through adolescence but into adulthood as well. Readers will be the as Michael grows and learns and matures. What I envision however is a full passing of the torch at the end. It has already been established that Michael is far from the first Titan and why should he be the last. The whole series could start over but with an entirely new main character. Michael could even be involved but let it go in totally new directions from the saga of Michael. Or, at least, suggest that would be the way it should all go. We'll see in the end, but I can't see what I have planned changing by much and what I see for Titan from there.
