Beyond the Blue: The next generation

Beyond the Blue: The Next Generation is a future story taking place many years after the final battle. It is the story of the ones that survived, mostly the children and the elderly. Main characters from the original series will appear, such as Lilly Harris, Brian Harris, Lance Carpenter, Adan Young, Boone Pell, James Davis, Gregory Jones and many other children that were born during the run of the series, such as William's fourth kid, Jason and Nora's adoptive child(ren) and Danny and Joleene's daughter.
==Concept==
About ten years have passed since the grand battle in which all the remaining aliens and the majority of the human forces met their demise. The sovereigns are no more, same as 95% of the adults that were 15 years ago. The remaining human survivors went into hiding, fearing any retaliation from remaining alien forces. Stuffed behind walls and underground, with depleting resources, the new generation of adults rise to the occasion to explore this new world.
==Ideas==
*There are going to be many differences in leechers from the previous series. There are going have mutated, and there are going to be many different kinds. 
#The normal leechers will now now be called zombies and only move in big groups. This is due to a mutation of their brain which allows them to know that they are more powerful in groups.
#Another kind of leechers are the hunters, creatures that each moves independently and are faster and more agile than the others. The hunter (as named) has big claws that uses as weapons, can jump up to 6 meters and is expert at climbing. It is unclear how some of these have mutated in this way, but the hunters are one of the deadliest enemies out there. The hunter can't turn a human into a leecher though. 
#The most powerful kind of leecher is the nuclear one. If approached in close proximity for a few minutes, it causes cancer. Its body burns, but it's rather easy to kill.
