Personal favourites from my own toy cupboard:

Cyborg and Muton (action figures)
Fighting Furies (action figures)
Pre 'gripping hands' action men.
Airfix 1/32 scale toy soldiers
Ricochet Racers
Steve Austin and Maskatron figures. (The latter had Steve Austin, Oscar Goldman and plain old Maskatron false face masks)
Space 1999 action figures. (Capt Konig, Paul Morrow and Alan Carter were the ones I had!!)

Forgot:

Lone Ranger action figure!! (With the Hopi Medicine Man costume, bought as an extra!!)
Cheap boxes of naff games - usually with the word 'compendium' in the title - which consisted of cardboard drafts, chess, blow football and equally uninspiring rot!!
'Timpo' toy soldiers.
