It was a sweet victory for The Undertaker on Sunday night after he beat Brock Lesnar during WWE's SummerSlam 2015 in a bloody battle.

Independent said this was the Deadman character's revenge on Lesnar for his first WrestleMania defeat.

Last month, The Undertaker returned to Battleground. The move cost Lesnar his chance of taking back the WWE World Heavyweight Championship.

"And it would be Undertaker who made the first blow, cutting the Beast Incarnate over the right eye with a heavy right hand - not before Lesnar rushed to the ring to attack his opponent before he even had time to remove his coat," detailed Independent.

During the match, Lesnar reportedly showcased a number of his known moves like the suplex but Undertaker had every answer to it, including his Tombstone Piledriver.

SB Nation reported that Undertaker's win was not really "straightforward" since a timekeeper's mistake became a distraction to the referee "allowing Undertaker to hit a low blow, then make Lesnar pass out in Hell's Gate."

The epic moment of the match, according to Independent, was when Lesnar laughed at Undertaker, a gesture answered with a "deranged laugh" from the Deadman.

For the Seth Rollins and John Cena battle, Rollins got unexpected help from critic Jon Stewart, who was also the host of the event.

According to USA Today, the comedian got into the ring and slammed Cena with a steel chair to aid Rollins' victory.

It was earlier expected that Stewart's presence at SummerSlam 2015 will be a threat to Rollins since he can spin the table on him, but it worked out the other way.
