The Transformers: Headmasters
In the Japanese series which ignored the U.S. series finale, Snapgragon first appeared in the 18th episode of the series, "The Most Important Thing in the World."
The Decepticon base on Chaar is suddenly upset when two newcomers arrive, and the Decepticons attack them, thinking they are Autobots. They are jets which possess the ability to transform into animals, then to robots—Horrorcons Apeface and Snapdragon—who have been asked by Galvatron to join his troops. The Autobots learn of the appearance of these two, and Spike, worried about the diminishing chances of ending the war, decides to seek out a peace agreement with the Decepticons before the galaxy is destroyed, despite the Autobots' concerns. Galvatron receives word of Spike's offer of peace, and Scorponok and Soundwave plan a trap, replying to Spike that he has to go with his entire family to meet in Shangri-La. Galvatron and Spike begin their meetings while Carly and Daniel are forced to remain with the Horrorcons, with the Autobot Headmasters remaining outside. Galvatron asks Spike for a token of trust - leaving Daniel with the Decepticons. Punch discovers Galvatron at the Decepticon base instead of Earth and reports Galvatron's orders to steal energy throughout the universe to the Autobots. The Headmasters mobilize to rescue the humans when they find out Galvatron is a fake. Galvatron then reveals himself to be Sixshot, leading to a fierce battle outside. The Autobots beat up on the Decpeticons, who escape through the space bridge. They try to follow, but Sixshot blows up the space bridge.
Snapdragon last appeared in episode 35 of the series, "The Final Showdown On Earth" part 2.
