Transformers figures from the first 2 years came from the
Diaclone and Microman Japanese robot toy lines. Beginning
in 1986 Hasbro began making their own toys until the lines
cancellation in America with the 7th Series in 1990. The
G1 series continued in Canada and overseas until 1992. 1992
is the year where it became hard to differentiate between
the G1 and G2 lines. This is because most of the toys were
released in both packaging.
