There's something about Galvie

Galvatron is a very manic little fellow..not just because of the whole insanity thingie but because of how he's been portrayed, so here I am trying to make things a bit clearer for you guys:

In the G1 Cartoon, Galvatron is simply the reformatted Megatron who's turned insane because of plasma baths. He eventually gets killed off my drowning or something in Headmasters (seriously, how did that kill him?!?!?!)

In the comics however, it's more confusing, there are at least THREE Galvatrons running around!!!!

Galvatron 1: The Decepticon who travelled back from the year 2006 and started the whole Time Wars storyline, culminating in his death by being torn apart by a time/space vortex
Galvatron 2: The Decepticon whom Unicron had kidnapped from an alternate future of 2009, where Unicron ate Cybertron and the Autobots are all but dead. He is eventually also frozen or drowned by the end of the comic series
Galvatron 3: The Galvatron who travelled back from some undisclosed date to the present day (well, present form their point of view) and tried to recruit some Autobots into his unknown agenda, but fails, and ends up in a dream like state on the Ark

On top of that, there's ANOTHER Galvatron!!!

Galvatron 4: After Galvatron 2 went to the past, and Cyclonus and Scourge followed, the Autobots followed, however after Galvatron etc are destroyed and the time/space rift is destroyed, the Autobots return home, but they find Galvatron alive again!!
Now this is a time distortion, basically they returned to a slightly alternate version of their home universe, where Galvatron etc never went back in time, however Rodimus and his team DID, meaning Galvatron conquered Cybertron in his absence

AND!

Galvatron 5: In Armada, Unicron sends a very G1-looking Galvatron to the Aurex universe to prepare it for his arrival. This Galvatron is of course killed by the local Megatron (AW)

Technically also, In the Fun Pub series Galvatron has been given his Universe toy as his body, but this is just for Toy-Accuracy

In Beast Wars Galvatron is some different guy who just took Galvatron's name, who is a narcoleptic but he does end up being an avatar for Unicron

In the Unicron Trilogy Galvatron is just an upgraded version of Megatron in each series

IDW have Galvatron appearing nowadays, BUT he isn't an upgraded Megatron, he's a totally separate character, but now he's gained the power of darkness, and will be appearing in the upcoming Infestation storyline (YAY!)

Galvatron is mentioned as being a future version of Megatron in Animated as well, but he hasn't been seen yet

Shattered Glass Galvatron has a Purple Helicopter mode and is a rebuilt form of him created by Primus and Nexus Prime. He seems to be quite a lovely guy though
