Here are just a few of the famous disses fired by AT Tupac.  Most of them are retaliation from disses FROM Tupac...

Biggie On Tupac

Biggie kept a remarkably low profile over their entire rivalry, and never dissed Tupac in public on any occasion.  However, he did take a slight dig at the rumours that Tupac had slept with his wife, Faith Evans, in one of his songs:

"If Faith had twins, 
she'd probably have two Pac's
Get it, Tupac's"

 

Mobb Deep On Tupac

Mobb deep fired back with a series of high-charged lyrics, angry at disses concerning a group-member's ill health.

"Yo, yo, We livin this til the day that we die, Survival of the fit only the strong survive, (We still livin it), We livin this til the day that we die, Survival of the fit only the strong survive, (Thug life, we still livin it), We livin this til the day that we die, Survival of the fit only the strong survive, (We still livin it), We livin this til the day that we die, (we livin this til the day that we die), Survival of the fit only the strong survive, (survival of the fit only the strong..)"   

"yo niggaz I'm testin', There's no question, bitch ass have you confessin', like a D-T left in state of depression, you under pressure, intact no doubt catcher, the snitch-snatcher tookin' wit asthma, you Casper, you yell my name, that's only givin' me props, plus the fans that you got, wondering what's got you hot, its too not, knocked out the box and got rocked, got raped on the Island, you officially got, kick that thug shit, Vibe magazine on some love shit, keep it real kid, you don't know who you fuckin' with"

Nas On Tupac

Nas never disses Tupac publicly or explicitly, but the following lyrrics from 'The Message' are allegedly aimed at Tupac:

"Fake thug, no love, you get the slug, CB4 Gusto
Your luck low, I didn't know til I was drunk though
You freak niggaz played out, get fucked and ate out
Prostitute turned bitch, I got the gauge out
96 ways I made out, Montana way"

Nas also features on the Mobb Deep track 'Thug Life Is Mine', a blatant diss at Tupac and the Outlawz.
