Okay so let's get this all together.
I think the idea of new characters works. Teenagers with abilities who were apart of Delilah's Organization.
Here is what I think... everyone feel free to let me know what you think haha..
We have a group of mutant teenagers who each had a close relationship with Delilah in each way. We can say The Six were killed in some mysterious event, and I think a good way to start the story would be the kids attending a special memorial for Delilah at The Lighthouse Foundation (that's the name right?) and we can have the kids mourn and try and figure out who was responsible for her death, and then we can segway to the kids banding together to carry on her mission, the mission of the six.
Then we can have MysTech realize who these kids are, that they have great potential and they are getting too close to uncovering that MysTech is responsible for the deaths of the Six, and can have them put on a hitlist. So the story can revolve around the kids fighting for their lives and each other..
We can have the kids have parents or not, come up with your own background, homeless whatever lol... but I think that's a strong starting point and it incorporates alot of the ideas we were bouncing back and forthe...
Whaddya Think?
