The god of thrash. Personally my all-time guitarist. Unlike little teenybopper bands around now like Green Day and My Chemical Romance, Dave Mustaine's band, Megadeth, plays a little thing called music. He was kicked out of Metallica after writing a large portion of their better music (a lot of stuff off Kill 'Em All and Ride the Lightning) but never received credit. Metallica is an awesome band as well, but in my eyes Megadeth will always be superior. Dave Mustaine is known for being one of, if not THE, best rhythm guitarists of all time. He can write symphonies of complex low-end riffing and put in screaming melodies and incredible lead breaks in the same 10 seconds. His playing abilities are also OFF THE CHARTS as compared to other rhythm guitarists. I myself would give a kidney, leg, and maybe an eye just to have his right hand.
Did you go to that Megadeth concert last night? Dave Mustaine's hands were FLYING when he was playing that 3rd solo in Hangar 18!

Dave Mustaine is a musical genius. He was kicked out of Metallica in 1983 supposively because he did drugs/he was in a fight with other members of the band. He, then formed Megadeth, which pwns Metallica in several aspects.
Dave wrote a song called "Something That I'm Not" about Lars Ulrich, because they were in a fight.
Here are some lyrics of the song:
"Unlike you, I'm no vision to myself, lest you forget
You didn't ever make metal, buddy, metal made you
To crush and roll over everyone along the way
Is something that you are, something that I'm not".
Megadeth Fan #1: z0mg liek Dave Mustaine pwns Metallica so badly!!
Metallica Fan #1: z0mg liek totally stfu, "Enter Sandman" pwns.
Megadeth Fan #1: Nah... "Kick The Chair" pwns that... but okay w/e.

The amazing guitarist (good singer as well) for the thrash metal band Megadeth. Known for being one of the bitchiest people on the planet (holds grugdes against all of Metallica, Slayer, Pantera, the dude from Headbanger's Ball, just about every member of his own band, Suicidal Tendencies, and Rotting Christ to name a few). Also formed the traveling Gigantour, a traveling tour much like Ozzfest, only good.
Dave Mustaine may be a whiny son of a bitch, but he can play really fucking fast, so it's cool.

Former Metallica guitarist. Was kicked out after being a drunkard/punching James Hetfield/not swallowing with Lars. They used his ideas for virtually all of their first two albums. Which were probably the only good ones. He decided to form a band called Megadeth. He was once in Metallica...he mentions it in every interview. Megadeth were one of the Big Four of thrash, along with Slayer, Anthrax and Metallica who Dave was once in. Dave is famously ginger. Recently became an uberchristian, but is still an amazing guitarist with a huge ego and a chip on his shoulder because of what those people in Metallica did to him. Wears flannel shirts onstage and can play riffs nobody else can. He was also once in a band called Metallica. Most famous for 'Hangar 18', 'Tornado Of Souls', 'Symphony Of Destruction', 'In The Navy' and 'Mechanix', which Metallica stole for 'The Four Horsemen'. At one time, Mustaine was a member of Metallica though so it's fine.
I heard Dave Mustaine was in a band before Megadeth, after Panic. I think it was slayer. No...Pantera. No...who was it?

After being kicked out of Metallica for being a whiney little bitch Dave Mustaine formed Megadeth a half decent band. Everything he does is second best leading to the catchphrase.... "Dave Mustaine sucks balls" I hear that.

Dave Mustaine is used as an insult to a person that is a whiney little bitch.

MEGADETH is the most amazing thrash/speed metal band in the world, they pwn your face.
I shall pray to the almighty Dave Mustaine tonight for your safety.

Former lead guitarist of Metallica, founder and main songwriter of Megadeth.
He is the pioneer of Thrash Metal and along with Cliff Burton, the only reason why Metallica had good music (he wrote their best songs on the first two albums).
As a band leader, he has the reputation of being a dictator but incidentally, this is also one of the main reasons why Megadeth has some of the best music in this world. Album after album is consistent unlike their rival Metallica, who again, incidentally, began to suck after Dave Mustaine's departure and Cliff Burton's demise (seriously, haven't you noticed that?!).

Dave Mustaine is a musical genius and is very charismatic.
Megadeth is way better than Metallica and most other bands for that matter. Thank you Dave Mustaine for existing.
