Birthday: July 2
Ruby is the main protagonist of the Ruby & Sapphire arc and recurring character of the Battle Frontier arc of the Pokemon Adventures manga. He first appears in Volume 15.
Originally from the Johto region, he moved with his mother to Hoenn to live closer to his father Norman, the Gym Leader of Petalburg City. Despite being a Gym Leader's son, Ruby hates battling and prefers Pokemon Contests.
Ruby began the series as a vain and condescending young man who did have a good heart deep down inside. The day he arrived in Hoenn was his eleventh birthday. On that very day, he ran away from his new home since he thought Norman would not endorse his choice to be a Pokemon coordinator. This was true at first, but Norman had decided to let Ruby become a Coordinator when the boy turned eleven. Sadly, Ruby did not stay to find this out.
After running away, he met Sapphire, the daughter of Professor Birch. They made a bet with each other - they would both travel around Hoenn, each trying to achieve their respective goals in eighty days — he would try to win every Contest and she would try to win all eight Badges.
His first three Pokemon are a Poochyena, Skitty, and Ralts, but he lends Ralts to Wally and due to an earthquake which sends Ruby into a raging river, he did not get her back until much later on.
Ruby, along with Sapphire, underwent an outfit change at the end of Volume 19. It is later discovered that under his cap is a scar he received from a Salamence years ago in Johto when he met Sapphire. He also has had a crush on Sapphire since he first met her in Johto and confessed that to Sapphire at the end of Volume 21.
Ruby may dislike Pokemon Battles, but he is in fact an extremely capable Pokemon Trainer in his own right, possibly as strong as or even stronger than Sapphire is. At the age of six, he actually liked climbing trees and Pokemon Battles. However, when he injured himself while protecting Sapphire from Salamence, the girl became frightened and cried. Ruby assumed there and then that the reason Sapphire was scared was because he fought too fiercely and too wildly. From that day onwards, he forsook Pokemon Battles, choosing only to Battle when no one else was watching him.
