My main character of course. I wanted to make a super solider type character who also has a good head on his shoulders. So you get to see the contrast between what he thinks and what he chooses to say. I've added a lot of subtle hints in his actions that don't mean much until you see the big picture.
Besides that, I like that he doesn't fall into the reluctant protagonist stereotype.
I think people are going to like him a bit more after his backstory arc.
Right now, the most liked by readers character in my comic is Strata, probably because she's a gremlin, followed by Luna Meerkat. And I think people are going to like Luna a lot more soon since the current chapters are about her.
