Kid Sidekick / Video Games


 * Henry Hatsworth in the Puzzling Adventure : Cole, for Henry Hatsworth. He's later revealed to be a "Well Done, Son!" Guy and in actuality the Big Bad in disguise.
 * Kirby : Sword and Blade Knight to Meta Knight. At least, in the anime. This was eventually carried over to  Kirby Super Star Ultra 's Meta Knightmare Ultra mode, in which Meta Knight could summon either Blade or Sword to assist him on his journey.
 * Maya Fey, the main assistant in the  Phoenix Wright Trilogy  may or may not count, as she starts 17 but becomes 19 by  Trials and Tribulations, although she tends to act like a little kid sometimes. Phoenix also had Ema Skye in one case when she was 16, and  Apollo Justice: Ace Attorney  has Trucy, who is 15.
 * 8-years-old Pearl Fey may also count in the missions where she plays a sidekick to Phoenix.
 * It's tradition for the protagonist of the  Ace Attorney  games to have a cute young girl for a sidekick. Or Gumshoe. Even Edgeworth teams up with Kay Faraday... and then it gets sent up when he's helped by Franziska von Karma. (who also briefly and hilariously becomes Phoenix's sidekick in the third game).
 * Miles 'Tails' Prower, sidekick of  Sonic the Hedgehog, is of the Gadgeteer Genius variety and has abilities that complement Sonic's. Later games introduced Cream the Rabbit (who has her own Sidekick, the Chao named Cheese), who serves as more or less the female counterpart to Tails (hence why they are often shipped together, despite almost never interacting). She started as a sidekick to Amy, but in  Sonic Rush  she acted in this capacity to Blaze. In  Sonic Rush Adventure , Blaze gets her own sidekick in Marine the Raccoon.
 * Cun-Cun &amp; Santi has Santi, Cun-Cun's little brother and companion on the adventure, who has the ability to travel over floor hazards and tackle steep hills. He's also faster than Cun-Cun.


 * The Silver Age-inspired  Freedom Force  computer games give us  Liberty Lad, sidekick to Super Patriot  The Minuteman.  Young Nick Craft, founder and president of the Freedom Force Fan Club, tags along after the team as they try to bring down mobster-turned-supervillain Pinstripe. Naturally, he gets shot.


 * Pinstripe: Now youse gotsta choose, heroes. Come afta me, or save da brat! Mentor reports that he needs an immediate transfusion...  or he'll die!  Minuteman, feeling responsible for the plucky youngster, valiantly volunteers to give his own blood to the boy. Mentor warns him that they have no idea what will happen, because Minuteman's blood is infused with...  Energy X.


 * Minuteman:  By the Constitution, Mentor,  there's no time!' The Energy X in Minuteman's blood gives Liberty Lad super strength and agililty and a penchant for red, white and blue tights. He's one of the more fun and effective characters in the game.
 * And from the same game, we have  Man-O-War  and his preteen sidekick,  The Sea Urchin.
