If Kane could be a representation of Scorpion, then Kanes older brother the Undertaker would have to be Noob Saibot - the reincarnated, demonic form of the original Sub-Zero, who was killed by his blood rival Scorpion early on in the series. Brought back to evil unlife in the Mortal Kombat iteration of Hell, the Netherrealm, the newly christened Noob Saibot is even more ice cold and inhumanly distant than he was as the frosty Sub-Zero, the harrowing hes received in Hell having removed all the facets of his persona that were ever human, leaving nothing but evil behind. Thats a fair approximation of what happens to the Undertaker when hes buried alive by Kane, moving from the relatively human-seeming American Badass/Big Evil version of the character to the deathly cold supernatural version once more (although its never made clear in WWE canon how he became human again in the first place). Babyface or heel, the undead Dead Man never kisses up to anyone.
