Thunderclash
Thunderclash is the name to two fictional characters in the various Transformers universes.
Transformers: Generation 1 (1992)
This toy truck was released in Europe as leader of the Turbomaster team. He did not Appear in any fiction other than his pack-in catalogue comic. Because of his bright neon colors, Thunderclash is often believed to be a part of Generation 2 - this is not the case; his Autobot insignia is clearly that of the Generation One design.
Botcon Europe 1999
Art of Thunderclash graced the cover of the Botcon Europe 1999 Souvenir Magazine, probably tying in to an article inside AbOUT European exclusive Transformers.
3H Enterprises
In issue 3 of the Transformers: Universe comic book Alpha Trion had computer screens viewing great Autobot and Maximal heroes from the past and asked Optimus Primal to choose several troops. Although Optimus Primal choose Depth Charge and Rhinox, one of the screens showed what appeared to be Machine Wars Optimus Prime, or possibly Thunderclash, which both share the same mold.

Thunderclash was later recolored into Machine Wars Optimus Prime, changed slightly for US safety rules.
Although the toy was never produced, a repaint of Thunderclash was planned and rendered in art for the Transformers: Universe line. Initially called Motormaster, then Menasor for trademark reasons, this repaint was black and done as a Decepticon.

The name Thunderclash was used for the Mini-Con partner of Skywarp.
Transformers: Universe (2004)
The Armada toy was recolored slightly and released in a Toys 'R' Us Spring Value Pack along with Ramjet and the Air Military Team.
