Here's my list for 2012
MOTUC Fisto - My first foray into MOTUC, and still one of my favorite figures from the line. Absolutely love that he came with the alternate head, removable belt, and the big ass sword.
Halo Anniversary: Master Chief "The Package" The Halo line of figures from McFarlane is a mixed bag for me. They're sculpts and paint jobs are some of the best I've seen, but the articulation is severely hindered by the sculpt. However, I knew I had to get this version of the Chief as he's just a fantastic looking figure.
Wal-Mart exclusive Avengers Hulk The first Hulk figure I've purchased and he's great. Just a hefty figure that really sticks out on the shelf, and really well done articulation for how big he is.
MOTUC Griffin Considering how many people love fantasy characters and beasts, there's a severe lack of them in action figure form. Griffin uses the Battle Cat base body, but the additional parts (especially the well sculpted head) make it an exceptional figure.
GI Joe Retaliation Joe TrooperThere was definitely a lack of quality Joe product this year, but this was not one of them. A plethora of new accessories, great articulation, and an awesome look (love the Halo-esque helmet) combine to make a great figure. I'm not used them as a generic Joe Trooper, but as a specific Joe called "Spartan" who does a lot of solo work.
GI Joe BBTS Marauder pack Mercer Overall I was pretty happy with the BBTS 7 packs, but Mercer is definitely my favorite figure of the bunch. The head sculpt is absolutely perfect, and I love the combination of Alley Viper and Viper parts. As a big GI Joe: The Movie fan it's nice to have a good Mercer (and the rest of the Renegades).
