I take it this thread has been done many times before, but I don't believe ALL of them were brought up. I tend to notice little details that most people wouldn't pick up on. Now, this list only includes the Movies/Comics canon (not count the Titan comic tie-ins), the toy-only and prequel novel Cons do not count (Toys being well, toy-only and the prequel novels due to heavy contradiction with the films) and definitely NOT the Cyber Missions. And thus: The last surviving Decepticons. NOTE: Some the characters were never specifically killed "onscreen", so it's still up in the air. But I will consider them alive (no matter how minor they may be) until I'm 100% positive they are in fact dead. 1. Igor - He was never killed in the movie or the comic adaption. 2. The Protoforms - I highly doubt all of them were killed in Dark of the Moon. I'm sure most of them will "evolve" into new Decepticon characters in the fourth movie. 3. Watch-bot - Never saw him again after he scurried through the grating. 4. The Hatchlings - See #2. 5. Garbage truck Decepticon - Never saw him again after he obtained his Vehicle form. 6. Pickup truck Decepticon - Never saw him again after the human massacre. 7. Thundercracker - Still alive. 8. Flatline - Still alive. 9. Stockade - Last seen fighting Payload. Never seen being killed. 10. Payload - Last seen fighting Stockade. Never seen being killed. 11. Ruination - Never seen being killed during Rising Storm. 12. Mindwipe - Never seen being killed during Rising Storm. 13. Space Case - Escaped. 14. Tankor - Escaped. 15. Sonar - Survived being stabbed and escaped. Warning! VERY minor characters incoming! 16. Thrust - Escaped at the end of Nefarious miniseries. 17. Lockdown - Escaped at the end of Nefarious miniseries. 18. Unidentified red jet Decepticon - Escaped at the end of Nefarious miniseries. And finally... 19, 20, 21, and 22. The 4 appliancebots brought to life in Transformers Nefarious Issue 5 - Never seen again after killing their owners. Welp. I hope that Bay or one of the writers is able to read this thread, just in case they finally want to end the series by killing every possible Decepticon in the last movie, I already have it ready.
