I finished redesigning another character from my alien project. Here's the new design for the Sentinel.

He's an Outlier who's fixated on watching over the galaxy and making sure other Outliers don't cause any problems. He doesn't trust any of them and wouldn't hesitate to banish them out of existence.

Since I made my OC, Stella, look like an empty space suit, I decided to do something similar with the Sentinel. He's basically a formless entity wearing armor. (He used to have leg armor but the Showman stole them. He's still very angry about that.)
