History
Pre-Series

Ash grew up in Pallet Town, Kanto, with his mother Delia Ketchum, where he developed his dream of being a Pokemon Master. He became close friends - and later, rivals - with his neighbour Gary Oak, the grandchild of Professor Oak.

At one point in his childhood, Ash attended Professor Oak's Pokemon Summer Camp, where he met a younger Serena. Ash helped Serena find her way back when she was lost in the forest, and helped patch up her injured ankle, too, telling her 'not to give up until it's over'.

At another time in the past, Ash signed up for Proffesor Oak’s Pokemon Camp but his mom had work that day so she couldn’t wake Ash up and so Ash had to wake up on his own. As usual, Ash overslept and missed the Pokemon Camp.

Original Series

On Ash's 10th birthday, he woke up late, and so was late to get his Starter Pokemon from Professor Oak. As a result, he was given the only Pokemon left - a disobedient Pikachu.

Ash travelled throughout the Kanto region with Misty and Brock, gathering eight Gym Badges, to gain entry to the Indigo League. During the Indigo League, Ash reached the Top 16, but was defeated by his friend and rival, Ritchie, after his Charizard refused to battle.

Ash, Misty and Brock then travelled to the Orange Islands, to retrieve the GS Ball from Professor Ivy, on behalf of Professor Oak. He decided to travel through the Orange Islands with Misty, to compete in the Orange League. While Brock stayed with Professor Ivy, Ash and Misty were joined by Tracey Sketchit, and a lost Lapras. After defeating all four members of the Orange Crew and gaining the four Badges, Ash challenged the Orange League, and defeated the Orange Crew Supreme Gym Leader, Drake, thereby winning the Orange League.

Ash, Misty, Brock and Tracey returned to Kanto, and shortly after, Ash, Misty and Brock decided to travel to the Johto region. They delivered the GS Ball to Kurt, for his research, and began travelling through the region. After gaining the eight Gym Badges of Johto, Ash competed in the Silver Conference. Ash managed to defeat his rival Gary, and progressed to the Top 8. However, Ash was beaten by Harrison in this round, and thus was eliminated from the tournament. Afterwards, Ash, Misty and Brock split ways, with Ash returning to Pallet Town.

After this, Ash, Brock, May and Max travelled through the Kanto region, where Ash decided to take on the Kanto Battle Frontier. Ash managed to defeat all seven Frontier Brains, and was offered the position of being a Frontier Brain himself. However, he declined this opportunity, as he wished to continue his Pokemon Journey. Soon after, Ash, Brock, May and Max parted ways.

Ash's next destination was the Sinnoh region, which he travelled through with Brock and Dawn, once again aiming to collect all eight Gym Badges. Throughout his time in Sinnoh, Ash developed a fierce and serious rivalry with Paul, due to their stark differences in mindsets about Pokemon and battling. Ash eventually gained all eight Gym Badges, and challenged the Lily of the Valley Conference. Here, he managed to defeat his rival Paul, and thus progressed through to the Top 4. However, Ash was defeated by Tobias, who had a team that included Legendary Pokemon. As a result, Ash did not progress any further than the Top 4.

Ash, Brock and Dawn soon parted ways, with Ash returning to Pallet Town.
