To make a really strong dragonite buy it from rocket game corner so what it costs money i havent beat elite 4 yet and i can make 100k in 1 hr next train it till it levels up then teach really powerful moves and feed it carbos calcium etc. then when it hits lv 100 it will be ultra powerful i did this with gryados in emerald over 500 hp!!!!!! also gender matters cause if you want def gyrados make sure its a girl if you want attack then make sure its a boy!
