Information on the Rapper:
Thanos, the Mad Titan, is one of the most powerful villains in the entire Marvel Comics Universe. He is a cosmic warlord from one of Saturn's moons who is literally in love with Death as both a concept and a person, and to this end has done many insane things to prove himself to her, usually involving mass-murder and most notably including his hunt for the Infinity Gems. Thanos has recently been revealed to have a heroic long-lost son named Thane and more recently still has been killed off in comics as part of the lead-up to what is expected to amount to a reboot of the Marvel Universe.
Thanos has recently become far more popular and well-known than ever before for his ongoing role as the main antagonist in the Marvel Cinematic Universe film franchise, where he first appeared as a cameo during the credits of the blockbuster hit The Avengers and is formally introduced in the just-as-popular Guardians of the Galaxy.
I'm throwing down the Gauntlet: spitting Gems of Infinite dopeness;
Wooing the woman of my worship with this intricate opus!
I'm resurrected once again and back to cause galactic harm,
And you can bet this time I won't end up retired on some farm!
I'll bathe the star-ways with the innards of this Deviant impostor
With Titanic rhyming, sharper than the blades up on my copter!
Take one look into my eyes; you'll panic like my matron parent did.
When Thanos gets to Rising, taking flight is quite Imperative!
With Cosmic Cube in hand, I'll A.I.M. to conquer space and time,
And when my fleet's on the attack, the only Sanctuary's mine.
I'm an Eternal-dreaded warlord, carrying out cross-cosmic slaughter,
And your title-claim's legit as Nebula being my granddaughter!
