Suna Light

Suna Light is Dr. Light's human daughter and Aki Light's "sister" in Mega Man: Fully Charged, having a role similar to Roll. However, unlike Roll, Suna is a human; not a robot.

Personality
Suna is an adventurous spirit. Her father taught her that anything is possible, so she has grown up to be an optimist with the eye of a scientist. She is smart, fun-loving and not afraid to get her hands dirty. Suna often plays the realist to Aki's unbridled optimism, but she is not cynical. She is bright, intelligent, and confident, but above all very human. She has a high tolerance for nonsense, but when danger threatens her friends and family, she is fiercely protective.

Abilities
Inteligence: She's very smart, and has an almost expert grasp of engineering.

Drone pilot: She's a good drone pilot, using one to asist Aki; providing information or in more direct ways using the drone to distract enemies, as well as setting traps.

Trivia

 * It is believed that Suna replaced Roll because having Roll be on par with Mega Man but retain her traditional role as a housekeeping robot would spark widespread backlash, due to modern sensibilities regarding female representation in media.
 * The name "Suna Light" might be a play on sunlight, with "suna" being the Esperanto word for "solar".
