Flareon

When Flareon breathes in air, it is heated in a flame sac inside Flareon's body to a really hot fire over 3000 degrees Fahrenheit.  It will fluff out its collar of fur to decrease its body temperature.
Flareon is the Fire-Type Eeveelution; in other words, an Eeveelution is an evolved form of Eevee.  Flareon has low HP, Defense, and Speed stats.  It kinda sucks, because you need Speed for lots of serious battles.  Low Defense stats makes Flareon weak to Physical moves.  Yikes!  Low HP also sucks, because when you take a hit, you won't have lots of HP, and therefore easily susceptible to strong moves like attacks with a base power of 150 or Super-Effective moves.  Flareon has okay Sp. Attack, and has really high Sp. Defense and Attack stats. High Sp. Defense is good, but you still don't have lots of HP stats in order to take a Super-Effective hit.  High Attack stats are really good, too.
If you want to give Flareon a really strong and Physical Fire-Type move (to get that Same Type Attack Bonus) you're going to have to be flexible.  It's strongest Physical Fire-Type move is Fire Fang, with only a base power of 65.  Some people don't really use moves with a base power of 65 or lower, so they might want to use the Life Orb to make Fire Fang stronger.  Otherwise, Fire Fang is an okay attack.  In 4th Gen., Flareon could learn Superpower by move tutor.  It's really useful in tough battles.  It's just not really good because Flareon has more Special Attacks than Physical Attacks.
Flareon's ability- Flash Fire.   You don't take damage from Fire-Type attacks.  When you are hit by one, the power of your Fire-Type moves increase.  It's just like Water Absorb or Volt Absorb.  People know not to hit Fire-Types with Fire-Type moves because THEY'LL JUST BE NOT VERY EFFECTIVE!  It's a poor ability on Flareon.
So Flareon doesn't add up to a really great Eeveelution.  It's useful for some things, but definitely not the best Eeveelution or Fire-Type at all.
