So here's a list of DC Universe Classics figures I've never seen. This does not include figures I've seen once or twice but passed on because they had bad paint aps/were broken in the package. Some of those include Booster Gold whom I saw once, but had random paint splotches all over him and looked as though his leg was severely warped and Flash who apparently sped off like his namesake never to adorn shelves near me again.

Wave 5:
Riddler
Black Lightning
Amazo
Atom
Eradicator

Wave 8:
Mr. Terrific
Hawkgirl
Gentleman Ghost
Parademon A or B
Commander Steel
Vigilante
Dr. Fate (Variant)

Wave 9:
Wildcat A or B
Black Canary
Mantis A or B

Wave 10:
Joker
Batman
Beast Boy
Forager
Joker
Man-Bat
Power Girl
Robotman

That's a lot of figures that I've never seen. Again, it's not so much even that I haven't seen all of these guys but it's the rarity of which I've seen the other figures. I saw Blue Beetle once. So yes, it's very annoying. Never having seen guys like Gentleman Ghost or even Vigilante at retail is frustrating. It was shortly after Christmas last year that I saw Wave 7 at retail... It's approaching Christmas the next year and I still haven't seen Wave 8 at retail. That's mind numbingly strange to me.

Obviously some of these figures can be found online at reasonable prices, but with DCUC I prefer to look at them in store. With any toyline you should at least see the figures at retail from time to time. One or two ultra rare figures is one thing, but DCUC is unique in having whole WAVES never show up. It's baffling.
