>>6864144As in Classics versions of 200X characters, or actual figures from the 200X line that ran while the cartoon was on the air?
For the former: basically all of them are good and some are great. Callix stands out to me as the best truly 200X character/figure. King Grayskull and Battle Lion are musts. Lord Dactus is cool and is pretty cheap, plus he's versatile for displays in that he's monstrous. Zodak is great, especially if you can get the unmasked head that was included with Strobo. Battleground Evil-Lyn is my favorite release of her character to date, it's a super solid figure.
You could also 200X-ize some characters with the head pack (pic related). They look pretty freaking cool, honestly. I was lukewarm to the idea but they came out great, and that kind of turned the tide on me enjoying 200X.
I was never super crazy about Prahvus, Carnivus, Ceratus, Evil Seed, or Chooblah, because they just seemed more like generic modern fantasy creatures that you could find in any media rather than unique monsters. Queen Grayskull (a.k.a. Veena) and Snake Armor He-Man were things that I skipped so I have no real opinion, though they look nice. Then the ones that I think are good figures but have no big appeal would be Marzo, Battle Armor Hssss, Faceless One, and Dekker. Can't recall any others, probably missed one or two.
