Cartoon HELIOS Understood in Two Frames (2コマでわかる！カートゥーン★エリオス) is a 2-panel web comic showcasing the lives of Heroes, along with information about the concept of HELIOS. Serialized from November 20, 2019 to December 22, 2020, Cartoon★HELIOS had a typical release schedule of one episode each week. The web comic seems to have ended with no known plans of continuing[1], stopping with the final episode being released at the end of 2020.
The end of each episode has an information segment that elaborates on one topic relating to HELIOS, which includes a note of advice by Jacqueline. Starting Episode 25, episodes no longer included the information box, and began being event-themed.
