Glasnost

Glasnost is an Autobot from the Generation 1 series.

Glasnost was one of the many casualties of the war for Cybertron before the launch of the Ark.

(Note: glasnost  is a Russian word for "publicity" or "openness". How a Russian word became a Transformer name millions of years before there was a Russia... then again, considering all the English-based names....)
