Science fiction and fantasy came to the forefront in many of the top comic book series in 2015.

The following are my selections for the 10 best comic book series of 2015. Check back next week for a list of the top 10 graphic novels of the year.

1. “Descender” (Image Comics)

Robot TIM-21 awakens in a world where artificial intelligence has become illegal. Writer Jeff Lemire and Dustin Nguyen chart his story as he heads for the home planet of the Robot Resistance. Nguyen's dreamlike watercolors help make a completely inhabited world that's a change of pace visually from most sci-fi comics.
