Hope the sign ups werent cut off yet. So, this is a mega evolution for Mightyena... but the catch is it's got two different forms. Kind of like MewTwo and Charizard, but these arent version exclusive, and also there is only one mega stone. The form it Mega Evolves into depends on what time of day it is, day or night. The first one is the Night form, and Ill be working on the day form soon.
Mega Mightyena Night Form
Username: SuperEspeon.
Pokemon: Mightyena
Type: Dark type
Stat Changes: +60 Attack (giving it base 150) and +40 Speed (Giving it base 110 speed)
Ability: Moxie
New Moves: Foul Play, Hone Claws, Knock Off, Pursuit, Torment, Parting Shot, Night Slash, Sucker Punch, Switcheroo, and Topsy Turvy.
Name & Location of Mega Stone: Mightyenamite, given to you after defeating Maxie the second time (Pokemon Ruby), or after defeating Archie the second time (Pokemon Sapphire).
Description: Mightyena is now perched on it's hind legs, and has developed a set of well defined, carved muscles rippling it's body. Essentially, Mightyena has become a werewolf. It's said that on a night of a full moon, a long, beautiful howl can be heard from miles, recognizable by all the hurt and emotion that strains within the howl because of all the darkness in the Mightyena's heart.
What I tried to do with this mega evolution was make all the improvements that were needed for Mightyena. I made it's stats less... just, average, by making 2 certain stats much higher, rather than equally distributing the 100 BST. Also, I improved it's move pool quite some, seeing as Mightyena doesnt have access to as many STAB moves as we'd like, even by TM. Finally, I gave it the design Im sure everbody has wanted or at least thought about: Mightyena Werewolf! Also, the staggering attack stat coupled with the Moxie boost should be killer in the meta game, but is balanced out by the fact that Mightyena's defense stats are still relatively weak, and untampered with.
Mega Mightyena Day Form
Username: SuperEspeon.
Pokemon: Mightyena
Type: Dark type/Fire type
Stat Changes: +50 Attack (giving it base 140) and +30 Speed (Giving it base 100 speed), and +20 Defense (giving it base 90 Defense)
Ability: Drought
New Moves: Sucker Punch, Fire Fang, Flare Blitz, Will O Wisp, and Flamecharge
Name & Location of Mega Stone: Mightyenamite, given to you after defeating Maxie the second time (Pokemon Ruby), or after defeating Archie the second time (Pokemon Sapphire).
Description: Mightyena's black fur has now been replaced with flowing and crackling flames that billow in the wind. His eyes now glow a tingent orange, a stark contrast to his grey skin. His paws are still black, unchanged. The tips of his ears are frosted an orange-y red. It's said that when Mega Mightyena runs, the billowing flames can be seen against the horizons from 50 miles away. For this form of the Mega Evolution I had a different approach. I distributed his stats a little more, and gave an interesting flare (pun intended) to him that I don't think anyone's thought of before (a complete contrast to the last form)... A fire Mightyena! It's ability is interesting, to say the least. This evolution was meant to give Mightyena a lot more type coverage, seeing as his normal self can only learn dark type moves and normal type moves. So, yeah that was really bugging me, and this idea sprouted.
