This Gogo was given away during the Daily Mirror promotion in the UK. A coupon was issued in the paper which could be redeemed at a local toy store for one of the figures. Both a green and a blue version were available for each figure. The two figures (named Alien and Dinosaur) were exclusive to the promotion, never to appear in any series.
The body mold is the same as Aka, the leg area of the mold however is widen more then Aka, this is most likely to support the larger head.
His design is similar to the classic Aliens series.
