2015 Convention Exclusive - Pacific Rim Replica Mini-Figures Box Set
Adorable, accurate and ready for action! This special edition box set includes poseable replicas of the Kaiju and Jaeger mini-figures seen in the hit movie Pacific Rim. Romeo Blue, Horizon Brave, Trespasser, Karloff and Hardship stand approximately 3" tall. Window box packaging.

NECA's latest ultra-deluxe kaiju action figure from Pacific Rim is the winged form of Otachi, with a massive wingspan of nearly 2 feet. 

It's extra-detailed, fully articulated and to scale with our Jaeger action figures, plus we've added a new feature... The included Flight Stand not only allows "in flight" poses, but can hold a Jaeger figure so Otachi can "carry" it aloft! 

Includes interchangeable tongues. 

As a special treat for collectors, the damaged tail stub on this figure can be removed to attach the full tail from the previously released Land Version of Otachi (sold separately).

Coming July 2015
Price $79.99

These are hitting stores next week and Horizon Brave will have firing projectiles, cool.

Jaeger Brawler Yukon which was from the Pacific Rim: Tales Of Year Zero comic is being teased by NECA, once official word hits we will post it.

 Shown at Toy Fair 2015 were NECA Chibi Kaiju and Jaegers from Pacific Rim. Note that these are from the film's prologue featuring the Jaegers Romeo Blue (far left) and Horizon Brave (far right), and the Kaiju, Harship, Trespasser, and Karloff.

"From the epic Pacific Rim movie! It might be the littlest kaiju ever, but Baby Otachi is just as deadly as its Category IV mom!
This freshly-spawned 6” long replica has an unsettlingly rubbery feel and features a detailed umbilical cord and bendable tail. (Angry Hannibal Chau and missing shoe not included.)"

April release for $12.99!
