Best SHF (Kamen Rider): Knight or Knight Survive
Best SHF (Sentai): Red Hawk (mine will be here Friday!)

Best SIC: I don't have TaToBa, so I don't KNOW that it's the best, so Skull/FangJoker - was that set released this year?

Best Star Wars: TRU Darth Maul Ultimate FX Saber

Best Misc: DC Chess Collection

Best Pre-2012 item I bought in 2012: SIC Kiva (or maybe the Den-O sets)

Hmm for me
best figuart would be...Den O sword form. Just had too much goodness and universal likability.
Best SIC...actually IT Side Basshar. This bad boy is quite ambitious and seems to meet its demands.
BoA figuarts Shining Red and gold tied...the fact they brought and released it to the domestic market.
BoJ well SRC Daizyujin...I love that figure...
Role play...that I don't touch...
best non toku? RID vehicon

Best SRC - Daizyujin ( only one i own , but it's still sweet )

i wont say it the best but the biggest surprise i found was the 4 inch shogun ranger. yea mor articulation would have been nice but the detail the put into the look and feel of him was unlike most other toys out there. im sure figuarts will put out a more fantastic version but for 7.50 its a nice addition to any collection

Figuart: Raia
Minipla: Go-Buster Beet
