Depending on when you ask me-because it cycles between the two often-it'd be either Dirk or Gamzee. Dirk is an infinitely interesting character to talk/write about, and I really liked his arc of trying to avoid becoming the villain he felt he was fated to become.

Gamzee is my favorite if we're talking strictly on character. I felt like a lot of his potential was squandered in ACT 6 in the sense that before the gigapause it seemed like more nuance was being set up for why he did what he did. He didn't need a redemption arc or anything, but I would've preferred him not being reduced to having "always been a bad guy."

Those are my thoughts off the good ol' dome.
