#2 Brock Lesnar vs The Undertaker (No Mercy, October 20, 2002)
No Mercy was an apt name for a pay-per-view which was headlined by this extremely bloody massacre that at times resembled something out of a horror movie.
The youngest WWE Champion in company history had something to prove after only seven months on the main roster and did so in stupendous fashion.
Lesnar looked every bit the beast as he tossed around his opponent, The Undertaker with ease and busted him open hard-way on the forehead, which caused 'Taker to gush blood like a fountain that covered himself, Lesnar and the ring canvas.
It was sickening but memorable. In another violent spot, Undertaker grabbed hold of Lesnar's manager Paul Heyman by his tie, yanking him by his neck-wear into the cell repeatedly. 'Taker's assault was so brutal, that he snapped Heyman's tie in half.
After 27 minutes of incredibly brutal action, Lesnar hit his opponent with an F5 and secured the victory, retaining his Championship.
As an aside, Lesnar completely no-sold the punishment he sustained in the match-up by scaling the outside of the cell (very quickly) and celebrated upon the roof, holding the Undisputed Championship aloft.
This was an intentional diss to Undertaker, who the previous month had refused to lose to the inexperienced Lesnar, which resulted in the booking of this match that 'Taker also had to be convinced to lose by the front office.
Lesnar didn't appreciate the disrespect and showed it, publically. The look on 'Taker's face as he gazed up at Lesnar was priceless.
