Andy's Charizard

Andy's Charizard is Andy's fifth Pokemon ever obtained.

With Green
Sometime prior to Green heading to Unova, she was walking down the Kanto Route 24 a trainer who wasn't good at raising Pokemon gave his Charmander to Green. Green eventually evolved the Charmander into Charmeleon and headed to Castelia City in Unova. Green really liked cave Pokemon like Swoobat and Andy really liked Green's Charmeleon, so they decided to make a trade Andy traded his Swoobat for Green's Charmeleon.

With Andy
After Green leaves Charmeleon becomes a new addition to Andy's team, during Andy's battle with Skyla, Charmeleon is unable to reach as high as a flying type but it begins to remember that a Charizard is a flying type and forces itself into evolution. After evolving into Charizard it is able to defeat all of Skyla's Pokemon and easily catch up to them. In the Kanto Arc, when Andy arrives in Celadon City he realizes that he has Squirtle and Bulbasaur and a Charizard back home meaning he has all three starters, so he decides to return it to his party.

Personality and characteristics
As a Charmander it's personality is unknown, but as a Charmeleon it usually likes to look and act cool and always train to become stronger than it already is. As a Charizard it's personality changed after evolving, it is now over protective, if something were to happen to Andy or any of his Pokemon than Charizard would go for revenge, similar to Oshawott also acting like a big brother to Andy's other Pokemon though only the ones Andy left in Aspertia City.
