Check out this Slide deck that has some integration ideas for using comics as a creation tool in your classroom. It was inspired by this blog article from Free Tech 4 Teachers, which is an incredible resource for educators and often has cutting edge ideas and suggestions that are simple, quick and easy to implement in your classroom. In the Slide deck there are some recommendations of software and apps that are Chromebook compatible as well as free to educators and students. The original blog mentions some products that require registration or have paid features and therefore may not be mentioned in the Slide deck.
