One is shiny and has Flash Fire. The other is normal colored and has Intimidate. Their IV's and nature can be chosen after catching. Which one do you want? --- A GameFAQs user from August 1, 2010 to March 27, 2012. Known as Megaleg back then.
Shiny, obviously... I can just take two steps and find another Growlithe with Intimidate anyways. --- http://25.media.tumblr.com/tumblr_mdtqd6EJTY1qlpahho1_500.jpg My husbando <3 QWILFISH for Smash 4! Also waiting on Qwilfish's Megalution, QWILSHARK!
