Transformation: Pull the front of the saucer forward and fold down under the saucer to form the feet and to reveal the legs. Push the sides of the saucer up and swing round to form the arms. Pull the red command post on the top of the saucer up to form the head.
Cosmos' robot mode is odd. Big green feet, thin yellow legs which bend at each end a fat round body, short dumpy green arms with yellow front panels and a head that's a red cylinder with a face painted in yellow over some moulded detail on the lower half. Unfortunately that then makes it look like the upper half look like he's wearing a hat!
I'm afraid my first reaction, as a 12 year old, on looking at Cosmos was "how silly". The UFO is a bit too fat and tall for my liking and I don't like the fat robot mode body and as for the hat .....
Cosmos was not released in toy shops in Japan during the original run of Transformers toys. Instead his Japanese version, called Adams after the aforementioned George Adamski, was available as a mail in toy in return for 2 robot points and 500yen. He was reissued in 2004 in the Transformer Collection #12 E-Hobby Minibot set which also contained Transformers Collection Bumblebee a re-mould of Original Bumblebee, Gears, Huffer, Powerglide and Warpath.
The E-Hobby Minibot set also contains:
Bug Bite
a Destron repaint of Transformers Collection Bumblebee which is a re-mould of the Original Bumblebee.
Road Ranger
a Cybertron repaint of Huffer
Small Foot
a Cybertron repaint of Gears
Bad Boy
a Destron repaint of Powerglide
Treads
a Destron repaint of Warpath
Each of the toys in this set has a name taken from the original GoBots toy line.
