I think it's Legion; a series based on an X-Men character named Legion, who is Charles Xavier's neglected schizophrenic son, but because of licensing issues they couldn't include most X-Men characters and as a result they created a story that doesn't really feel like any other superhero thing and is instead very weird and very trippy.

I haven't watched it since it's original run and don't remember much more than that, but I remember liking it quite a bit. I might rewatch it soon.
