The Very First Charizard or Why the Char-Family Have Burning Tails
by Marikunin/GirlWaterShaman

Long ago, the Char-family had not tails of flame. But this all changed one fateful day. A Charmeleon and Wartortle were stopped during a long journey by a Gengar. Mad from sufferings unknown, he demanded of them penance for safe passage.
When this order was denied, the enraged Ghost challenged them to a battle. It raged for a day and a night, for the Gengar had few weaknesses.
Eventually, the Charmeleon and the Wartortle were facing the door to the next life. The Wartortle begged the Charmeleon to do something, for the fight had made her unable to stand.
"I am not yet ready to leave this world," said she, "for I have yet to truly love."
Now driven to somehow save his precious friend, the Charmeleon felt a great heat erupting from within. About to burst from raw power, he guided the energy to his tail; the only non-injured limb.
The new flame on his tail grew until it enveloped the Charmeleon completely. When the flames faded back to normal size, a majestic beast was in his place. The Wartortle was now protected by the very first Charizard.
Seeing this new, fearsome creature, the Gengar tried to flee but was prevented by the Charizard.
"Harm not any creature from this day," the dragon warned, "Or I WILL return to seek vengeance for their sakes."
Finally, a loud Roar chased the Gengar away, and the duo continued on their journey.
This is how the Char-family gained tails tipped with fire, and the birth of the very first Charizard.
