I have started customising Linus the Saurian in Mego 8"-scale, using a spare Saru figure and uniform, an experimental resin head I have had sitting around for about 20 years (made by a 'net pal) from an enlarged Mego "The Motion Picture" 3.75" Saurian (originally misnamed a Rigellian by Mego in 1980).
