Sparky is Galactic Guardians' captain Atomic Betty's alien lieutenant and is
also the pilot of the Starcruiser with pointed elf like ears, a large, round olive green nose, light green colored skin, and light blue colored hair, and his species is known as Neutropians. Although he is sometimes a bit reckless, and often more interested in other things, such as eating (mostly), surfing, or girls than the current Galactic Guardian mission he is on, he is nevertheless very loyal to both Betty and X-5, and endeavors to do his very best at all times. Also, despite the immaturity that he expresses in various things such as quarreling with the robot navigator and his fellow crew member, X-5, he is shown throughout the early episodes of the TV series to be very skilled at both piloting the Starcruiser and being a combatant.

After Galactic Guardian Headquarters was moved to the planet of Earth and was rebuilt underneath the school of Betty's home-town of Moose Jaw Heights in the Mission: Earth season, following the events of the premiere third season episode "No Space Like Home", Sparky has had an increased presence in Betty's personal life; he is attending Moose Jaw Heights Junior High School in disguise as a new classmate and friend of Betty who, according to Betty, was purported to hail from Saskatoon (using the same disguise that he first used in the episode Bracelet Yourself). However, with more situations in Season Three taking place on Earth due to the relocation of headquarters, he has rarely been seen piloting the Starcruiser, and is often distracted at times when Betty or X-5 need his assistance.
