Metagross has higher Defense (130) than Tyranitar (110) though, on top of being too slow...the stats line up worse. Tyranitar is probably the *best* match, still have to scan the 600s' stats, including Hoopa's and the like. XD Her Mega on the other hand...definitely not Mega Aerodactyl. XD

Unfortunately, not as of the moment, hehe. >.< I'm going to work on our private RP and this for now, hehe! XD
