This is a solid little comic series. It starts with a young, rich genius named Hiro Takachino and his robot bodygard Baymax tracking down his idol, Sunfire.
Sunfire is dying from his powers. The three–plus a few others–are recruited by Silver Samurai to join a new hero team. Although Sunfire says he’s too sick to join, Hiro tells him he’ll help figure out his condition.
There’s an adventure–a fun one–involving a villain who kidnaps Hiro’s mother, but the real story is that Sunfire DOESN’T get cured. After they save Hiro’s mother, Sunfire heads to Canada to try to find a cure through their Department H.
Despite the themes of dying and death, this is a terrific “all ages” book.
