"How can we know for sure... unless we... try for ourselves...?" —Maduin 's response to Madeline's uncertainty regarding humans and espers co-existing. Chaos Wave/ Wing Maduin is one of the few summons that plays a direct impact to the plot line in the Final Fantasy series. Because of this, he doesn't appear in other installments. I think he shows up in Final Fantasy World, but mostly in his relationship to his daughter Terra. Which is a shame as cus i think he's cool. Terra apparently will do "Chaos wave" in Dissidia, as well as some other boss characters in other games. I drew Maduin facing forward to symbolize how he's different than the other espers in so much that he believes that humans and espers can coexist
