We wish to extend a special thanks to Cartoon Network PR Department for providing us with official character bios and information.

MEGATRON is a fierce, unyielding despot who sees himself as a freedom fighter. He sees the DECEPTICONS as an oppressed race suffering under the tyranny of the AUTOBOTS. The DECEPTICONS must survive by any means necessary. He takes extreme pleasure in the suffering of even a single Autobot. And MEGATRON does not care at all for the collateral damage known as humans who might happen to stand in his way. He has the zeal of a fanatic and demands the unquestioning loyalty of those who serve him. 

Robot Mode Power: MEGATRON begins the series with only one power: the power to lie and manipulate Sumdac to repair and reconstruct him. Over time, the MEGATRON head will develop into a powerful psychokinetic who can control any machine. While the Cybertronian minds are too advanced to succumb to this ability, MEGATRON can control virtually any robot on Earth and the automated plants that construct them. In addition to this power, MEGATRON’s eventual robot body will be equipped with an assortment of laser cannons, sonic missiles and pulse blasters. 

Vehicle Mode Appearance: Earth Mode Attack Hellicopter 

Character description from package "tech spec":  Now that he has finally ben able to build a body for himself, Megatron is more powerful than ever, and no force on Earth can stand against him.  He is a fighter without equal anywhere in the universe.  Backed up by his Decepticon soldiers, he is also an expert battle leader, without peer.  He is as ruthless as he is ambitious.  Megatron will stop at nothing to gain the AllSpark, and destroy Optimus Prime and his Autobots.

Galactic Powers and Abilities:
>  Expert two-sword fighter
> Genius-level engineer and programmer.
> Armor can deflect even focust anti-proton lasers.

Bibliography of significant appearances: In this form, with (Earth mode helicopter) his Cybertronian Alternate mode, he made only a few appearances, most notably in the Transformers Animated movie introduction: Transform and Roll Out.  Of course, it was this form's decapitated head which featured so prominently in the series until his return with Earth mode helicopter.

Other appearances:

Don't hold your breath as we get through this, because this could take awhile!
- 1984 -  his original toy form so incredibly bad@$$ it is actually an illegal toy in the U.S. as an exact replica of a real firearm, the Walter P-38 handgun.  Since he was reformatted into Galvatron by Unicron in TFTM, he made shockingly few other appearances in the G1 series.
- 1987 - as a decoy
- 1990 - in Action Master form
- 1993 - Generation 2 (G2) green and purlple tank, surprisingly, it was his first vehicle form!
- 1994 - G2 air power rocket launcher
- 1995 - a very uncool " gobots" version
- 1996 - Beast Wars Alligator and the very well known purple T-rex Beast Wars Megatron
- 1997 - Machine Wars Megatron, his first jet alternate mode ever!
- 1998 - Beast Wars Transmetal Megatron, (my personal favorite!).  In the Japan only Beast Wars II series, there was Megastorm, who is close, but apparently not quite Megatron!
- 1999 - Beast Wars Transmetal 2 Megatron, Beast Wars Neo had Magmatron, also a reasonable facsimile but still not quite Megatron. 
- 2000 - Yet another close-but-not-quite was " Mechatron" Beast Riders in Beast Machines and Beast Machines (Mega class) Megatron.
- 2001 - Here's an interesting case!  His name in the show was "Savage" in dragon mode, and "Noble" in wolf mode, and the toy is called, " Beast Changer."  But really, he *is* Megatron!  Then, later that same year came the first 6-changer Megatron in R.I.D. Transformers.  Wow what a toy!
- 2002 - In the fist half of the year was a toy with limited release.  It's Beast Machines 'floating head' Megabolt Megatron, sold in R.I.D. packaging (Hey, we'll take it!)  With the beginning of what fans would later dub, "The Unicron Trilogy" came Armada Megatron.
- 2003 - amazingly, not a single toy named Megatron!
- 2004 - Energon Optimus vs. Megatron 2-pack (limited release), Energon Megatron.  In the Japan-only series "Robot Masters" there was Beast Megatron.
- 2005 - Legends Class Megatron and the very popular Cybertron Megatron (Leader Class)
- 2006 - Okay, here is when it really starts getting out of hand!  Let's start with the Takara-Tomy (Japan only) Masterpiece Megatron.  Cybertron (deluxe) Megatron then his first appearance as a gun in 22 years: Classics Megatron  and Ultimate Battle Optimus Prime vs. Megatron, Beast Wars 10th Anniversary Megatron.  Botcon 2006 pre-prehistoric alt mode Beast Wars Megatron (a recolor of Cybertron Ultra Cybertron Defense Red Alert), Titanium 3" Beast Wars Megatron, Titanium 3" Cybertron Megatron, 6" Titanium Megatron (based on GI Joe crossover comic?), let us nevermind the Attacktix version of this character for now!
- 2007 - Many toy forms relating to the Movie: Legends Class, G1 Real Heroes, Movie Real Heroes, Fusion Blast (FAB) Megatron, Robot Replicas, Robot Heroes vs. Pack, Voyager Megatron (frozen), Voyager Megatron (metallic) Megatron Unleashed, the definitive Megatron toy of the year Leader Class.  Then Titanium 3" movie Megatron, Titanium 6" War Within Megatron.
- 2008 - TF: Animated Activators Megatron, Voyager Megatron Cybertron Mode, 2-pack Deluxe, Leader Class Animated Megatron, Botcon Exclusive Shattered Glass Megatron, Transformers (live) Movie Fast Action Battlers Night Attack Megatron,  Premium Movie Megatron, Classics/Universe Legends G2 Megatron, C/U Robot Heroes Rattrap vs. Megatron, C/U Robot Heroes Silverbolt vs. Transmetal Megatron.
