I have been having an interesting thought about one of the main character for my sequel series. Even though he will be one of the most powerful characters I ever created, he will have one major weakness. His power is completely dependent on his ability to form emotional connections with those around him. However, he will be psychologically vulnerable and mentally withdrawn due to a traumatic experience he had as a child. As a result, he has not been able to access his full potential for years and throughout the sequel series he has to learn to slowly come out of his shell and connect with people therefore unlocking his true power. Not since Vogan have I created a character this complex and I look forward to tinkering with him further.
This will be great!
That will be a good premise. The main character in my Frank Rozzani detective novels has a traumatic event in his past that keeps cropping up to affect his current life. It makes for a good story arc over a series.
