The third evolution for a lot of the Pokes is pretty Digimon-ish.
Though this wasn't true for RBY and GSC (Dragonite, Charizard, Gyarados, etc. look just fine), it is true for RSE and DPPt. Hoenn and Sinnoh seem to have many 'armor plated' almost-robotic final versions and legendaries, like Groudon, Dialga, Palkia... and third evolutions like Blaziken.
They seem to have dialed it back with Generation 5 (BW), since a lot of the third evolutions aren't ridiculous crazy super-armor dudes (though Samurott gets kinda close). Evolutions like Gothitelle, Reuniclus, and Leavanny, look pretty lithe and not over-the-top, and even the legendaries look more like dragons with something attached to their tails (Reshiram) rather than heavy Transformers.
