Heh, I had the idea that if my Totodile Joseph could "Mega Evolve", because of a side effect/"Mutation" from the Chozo Blood in his body, he would gain incredible strength (Muscle strength, not as in Attack stat, Strength stat, etc.) while in that form.
i wish this was indeed a mega form of feraligatr or should i say feraligatrite for pokemon x & y and hope that there was a mega form for typlosion, sceptile, lugia, serperior, flygon, krookodile & salamence as well. but like what nintendo said that not all pokemon will have a mega form. only a few.
