So I'm playing through Heart Gold again, just because. In the beginning I was all, 'I want a fire type but not Cyndaquil, Magmar, or Growlithe'. Ponyta is on routes 26 and 27 and Slugma and Houndour are in Kanto too(hahahahaha), and I told myself that Ho-oh was off limits so Flareon was left.
So yeah, Eevee from Bill plus a traded fire stone, aww yeah Lucky Egg for days. And that base 130 attack gets in there, Ember? Please, Headbutt+Strength all day. Fire Fang at 43 woo(shame Flareon didn't get Flare Blitz in gen 4)
Tanking(more like nullifying) Ho-oh's attacks and junk, base Flareon
Also Lyra for best(and cutest) player character, oh and Leafeon is still better than Flareon.
