Who is your favorite Stranger Things character?

Stranger Things is one my favorite television series of all time, I even watched all the eight episodes in one day. It is a very interesting series and I really enjoyed watching it, though some might find it overrated or boring because of its setting.

One of my favorite characters is Lucas Sinclair played by Caleb McLaughlin. I honestly think Lucas is the most level headed and courageous among the kids, he's not easily deceived, he is strong-willed and not gullible, he always thinks before doing something. He may be serious, but I think he's the most reliable in terms of saving their friend Will.
