>>44690894No, but you would have a stronger argument for his beta design being so. Same with Snover and Abomasnow's, which are very Gen 1.
Some Pokemon I can think of that fit the bill as very Gen 1 in their style (ignoring Gen 2 since that's too easy)
>Aggron>Carnivore>Avalugg>DragalgeThere are also other Pokemon that aren't themselves in a Gen one style but also wouldn't be out of place in Gen 1, if that makes sense, like Mawile and Sableye.
