Here is my 2nd entry in the Mega Form contest by Cachomon at Deviantart, also made in Sugimori style.

It is Mega Reshiram and all it's glory. It's form basically stays the same, just with armor parts that resemble it's Ideal Counterpart Zekrom. Looks like Reshiram becomes somewhat complete as he gets a hold of the Black Stone.
