It's rare to find rap superstars as bizarre as Lil Wayne, but Weezy himself scrounged one up circa 2007. That's when Nicki Minaj made her first memorable guest appearance on his "Da Drought 3" mixtape.

It's rare to find rap superstars as bizarre as Lil Wayne, but Weezy himself scrounged one up circa 2007. That's when Nicki Minaj made her first memorable guest appearance on his "Da Drought 3" mixtape.

Between references to flashy fashion ("Steady starin' at my ear 'cause my ear on glare") and audacious sex, Minaj described her budding partnership with Weezy: "You be Harry Potter and I'll be Hermione."

Wizardry suitably describes the way both rappers have channeled their madness into ubiquity on the charts. They're serial guest stars that gobble up the scenery wherever they roam. Meanwhile, each uses a slew of solo releases to create kingdoms they rule with deranged gusto.

Minaj's ascent hit full stride when Weezy was heading to prison on criminal weapons charges. Now that he's free, he's taking his protege on a tour that hits Nationwide Arena Saturday with Rick Ross, Travis Barker and Mix Master Mike.

To prepare, let's look at the tics that make Weezy and Nicki such strange superstars and decide who's more insane.

Sounds like:

Weezy: A mischievous cracked-out goblin

Nicki: An unstable schizophrenic

Appearance:

Weezy: He gets tattoos almost as often as he generates new songs.

Nicki: She dons a colorful new costume almost as often as Lady Gaga; her collection of zany wigs would make a Spice Girl blush.

Lyrical o bsessions:

Weezy: His sports fandom is best evidenced by "Get High, Rule the World," in which he proclaims, "I never miss a game, no Shaq O'Neal/ More like Brett Favre," then namedrops Frank Gore. He frequently raps about eating, drugs and space; a neat summation: "I'm so motherf---ing high I could eat a star."

Nicki: Barbie creeps into most of her songs; she even rapped over a sample from Aqua's "Barbie Girl." Nicki's into other kid stuff: check the aforementioned Harry Potter reference and "Roman's Revenge," which posits, "I am not Jasmine, I am Aladdin."

Controversy:

Weezy: The documentary "The Carter" confirmed his cough syrup addiction; he served prison time for weapons possession.

Nicki: She beefed with Lil Kim; her alleged role in a sex tape was debunked.

Most terrifying verse:

Weezy: His twisted braggadocio on "A Milli" includes shockers like "I'm a venereal disease like a menstrual bleed."

Nicki: Her rip-roaring turn on Kanye West's "Monster" shamed peers and left listeners trembling: "OK, first things first, I'll eat your brains/ Then I'mma start rockin' gold teeth and fangs."

Verdict: Though Nicki's a more colorful character, her madness didn't get her locked up (or inspire her to release "Rebirth"). Wayne remains the craziest.
