The items I'm after for each Dragon Pokemon are the following:
Pokedoll (or another plush, if no Pokedoll exists)
TOMY (Monster Collection) Figure
Zukan (1/40 Scale Gashapon)
Kids Figure
Pan Sticker
Any other items I may hold on to for my collection if I get them as part of a set or lot *cough* Palkia *cough* but I am not looking to buy any and everything of these Pokemon! Also, for Pokemon that have more than one of these, I only need one - I don't need every Pan sticker made of Rayquaza, for example.
This idea was very much inspired by Gin of Sunyshore's electric-type collections, so if you enjoy looking here, you should definitely check out Sunyshore!
I've finally managed to procure the 3 bell plush for this line, the only dragon types with official bell plush. (Dratini isn't here yet, though.) These guys are fun to collect, if a bit too popular to make everything easy to get!
Coming Soon: Once the Dratini bell plush arrives, I'll be all done with these guys~
The only Dragon in the line, and so the only one I collect! Not much stuff exists for him, though. Poor guy!
What's missing: Just a plush!
Coming soon: Kingdra Johto metal charm. I haven't had much luck with commissioning an artist to make a plush of him, they keep flaking out on me...
These guys don't have Pokedolls either, so I'll use custom plush to fill in the gaps. I'm not collecting Trapinch since he isn't Dragon-type, but Vibrava is definitely included. His custom plush is a commission from Lonepichu!
Not shown: A Flygon custom plush in the Pokedoll style, also from Lonepichu!
What's missing: Since I try to get a plush from a different artist for each Pokemon, I'd like to get a second Flygon made, as I already have Vibrava from Lonepichu.
The singing bird. She's very lucky to have a Pokedoll
made! What's missing: Nothing! Collection complete. If I happen to find a few more items of her, I may grab them, but it's not a high priority.
Yeah...as you might guess, I collected Salamence before I
started this
project. I love the big dragon in game and started collecting him
<3
What's missing: Nothing! Collection complete, although I want to get all of their figures and most of Salamence's other stuff. My top wants for them right now is a Retsuden stamp for each - yes, even Shelgon got one! I've always been fond of these guys, too. The Zukan was a
mini-grail
for me - as soon as I found out there was one, I went crazy trying to
find it. I lucked out and got it for a total of only $18 (while the
Kingdra zukan went to 4800 yen, what the heck?) I don't collect these
two hard, but I'll pick up cute items if I see them, or pull them from
lots I'm selling. ^_^ Although I haven't bought most of the items as
pairs, they ended up mostly in matched sets anyway, which I think makes
them a nifty collection. What's missing:
Nothing, yay! I've always liked him, too! A lot of Rayquaza
plush (including this Pokedoll) have really weird mouths, but I like
the figures! This guy has been really easy to collect, as there are
many figures of him that appear in figure lots I buy (usually while
trying to get Dialga items). What's missing:
Nothing! Not shown: Another version of that tiny on-Pokeball figure. Since these guys are from Diamond Pearl, yet aren't movie
stars (at
least not yet), some of the stuff I need for my major collections will
hopefully be released sometime soon. Their Zukan is the most recent
release, and I'm hoping Gabite's Tomy will be released soon. I'm REALLY
hoping at least one of these will get an official plush, or maybe even
a Pokedoll! Garchomp UFO plush, yes please. The Gible plush is a custom
shiny female bell plush, made by ambertdd of pkmncollectors! Not shown: Gible/Gabite/Garchomp pan sticker, forgot to include it in the latest photo here... What's missing: Gabite
Tomy doesn't exist yet, and neither do official plush of any of
these. Coming soon: Gabite custom plush! See the rest of this site. ^_^ I have all variations of the 5
key items for Dialga, except for the really huge 60cm Pokedoll! Where there are Dialga, Palkia usually tag along, although
not in the 11th movie featuring Giratina. There were many
extra
items in this collection for this reason, but I have sold off most of
them since I don't really need as much of him. What's missing:
Nothing! Collection complete. I wouldn't mind the DX Pokedoll if I see one cheap, though! I don't really think I MUST collect
both
formes, but since Origin Forme (as well as Another Forme) were all over
Japan for the movie, I thought I may as well pick up the 5 items I
collect. There are a few extra items in here such as the DX Kid of
Another Forme, and the 18" Tomy plush of Another Forme to match my
Dialga and Palkia. What's missing:
Nothing, yay! I picked up a few more Giratina items the last time I was in Japan, so this collection has grown a little, but I'm not looking for anything of him right now. Although Arceus himself isn't a dragon type most of the time, he can be if he's using a Draco Plate! We thought that probably Arceus's formes wouldn't get much, since there are 18 of them and that's a lot of variations to make, but so far they've gotten UFO plush, zukan, Tomy Figures, and Chou Get! I would have preferred a Pokedoll, but I'm happy to have the UFO plush anyway!
Altaria
Not shown: UFO plush!
Bagon, Shelgon, and Salamence
I
really like this collection, but poor Bagon and Shelgon are really hard
to find anything of. Since they are two of the 3rd Generation Pokemon
that never had official Tomy figures made, I had to settle for the
bootleg versions, but I also filled the gap a little with the Hasbro
(to scale) Bagon and the Pokedex Figure of Shelgon. 
Latias and Latios
Coming Soon:Two more Pokedolls - they got reissued in minky fabric with new patterns!
Not shown: Latios's
Chupa
Chup figure was on my desk and I forgot to include him until later,
whoops! He's not part of the major 5 anyway though....
Rayquaza
Gible, Gabite, and Garchomp
Dialga
Palkia
Giratina
Draco Plate Arceus
So far there is no Kids figure or pan sticker (or any kind of sticker for that matter). I could have a normal Arceus Kid painted Draco Plate colors, but what about the pan sticker? Maybe I will have to try and draw one!
