>>43618104nta but I think that base Metagross has a unique simplicity and coolness to it that Mega Metagross, while still way less busy of a design than most Megas, fails to beat.
It's pretty apparent that it's not supposed to keep the same inconspicuous-but-dangerous feel but instead be a big scary fighting machine, which it obviously shares with every other Mega. That said it does have a respectably modest design, so I agree with you that it is able to continue the general vibe of the line. I wouldn't say it fulfills the same visual niche as base Metagross though, so I can see where that anon is coming from.
I'd be interested to see if recoloring the cross from gold to silver would make it look more natural, which admittedly goes against the point of a Mega, but what can you do.
