Here's an excerpt from an interview with comic creator Carlo Vergara:

BW: You said that the characters are based on real people. Are you part of the cast?
CV: Admittedly, each of the characters has a part of me. I'd like to think that's common in a lot of creators when they write different characters.

The thing that pops into my mind is that in the same way the Creator imbued not a part of him in his masterpieces but his very own image. Wow.
