Mega pidgeot got a Mega evolution, so I think its only fair for there to be a Mega staraptor. Mega staraptor would gain the fighting type, making close combat a STAB move. It also gets rid of staraptors weakness to rock. Staraptor would get a boost to its attack and speed with a small boost to its defense stat. It gains the ability Moxie, making it a powerful sweeper. Mega staraptors appearance is a spikier, more prominent head tuft, as well as red stripes in its wings and tail. Its claws and wings and tail are bigger. staraptor now would look more vicious and intimidating.
Stat boosts:
50 attack
40 speed
10 def
