Cyborg & Muton

Towards the end of my childhood now, and these two really rather neat figures.
Like so much from back then, they just appeared in shops and catalogues, with no idea of their origins.
I loved them both - Muton for his coloured clear body and natty fish costume i also had, and Cyborg for his strap-ons (so to speak).
Would love to own them again, but not at the hundreds they command on the 'Bay.
