Bionic Rim - (Bionicle/Pacific Rim)
Starring Giga Rail as "Gipsy Danger" and Ragnorahk as Kaiju #1.
Giga Rail stands exactly 2 ft. tall and is currently the largest single Lego figure of any kind that I have built (let alone a Bioformer)! Alt mode is a train and he has two light up inika swords to "power him".
In case you can't tell, I LOVED Pacific Rim! Awesome all the waayyyyy!
