What is "thunderwing"

Thunderwing is the name of several fictional characters from the Transformers series. Introduced in 1989, he was a major villain in the Marvel Comics Transformers series. Although Thunderwing was created after the US Transformers television series ended, the character of Black Shadow did appear in the Japanese Transformers series, who was based on the same design as Thunderwing. In later years other characters have carried on the name Thunderwing in the Transformers line, including two Mini-Cons and a mirror-universe version of the original character, who was a law enforcement officer. In 2010 Hasbro released a new Thunderwing toy based on the original character.
