Dark Legend

Well... I just think that would be unfair for one evolutionary line can Mega Evolve, and other can't. What makes one better than the other? Lorewise, all non-Legendary fully evolved Pokemon could Mega Evolve... But we know why it's impractical. 

Also, I'm not the only one to create Mega for "regional" variant - like Mega Deltas who... true, they're "half-artificial", but can be treated as regional variant with the same premise as regionals. 

And the other reason is to... make a battle against Oscar a nightmare (unless someone brings Perish Song/Destiny Bond/Counter Sash Pokemon to counter that specific monster). 

I've done the calcs, actually... And taking the "Blessing" mechanic into account, Earthquake from Max Atk Mega Garchomp during Sandstorm will do... a maximum of 33,4% to that specific Sacronian Mega Tyranitar, assuming both are on the same level. And only because of Sand Force! Without it, there's a slight chance Garchomp won't 5HKO it, while Tyranitar will 2HKO with Dragon Hammer (a bit "changed" so Pokemon don't have to have a long necc - just long, powerful limb). Of course, you won't receive such overpowered Pokemon when you get to that battle, so the actual damage done will be even lower. 

Players may cheese the fight, but since it will be 6vs6... you know what, I've said too much already. 

I... am far too away from creating the game; I still haven't created evil team's Admins (expect names and general asthetics) and almost no unique "side characters" except Professor and some Frontier Brains. And all... That is when you create it alone, and also study, and have almost no artistic talent whatsoever. 

Ideas, I do have - lots of them. But having to paint them is x100 times harder. And often I "copy" others. Not steal, but copy - take inspirations, and "upgrade" them. 

...okay, now I'm whining. Sorry

My evil team is called Team Nightmare. You got yours yet?

Yeah. 

Team Omega - basically a mix between Team Plasma and Team Meteor with some spicyness.
