He's a ruthless beast in the ring but every fighter will meet their match at some stage. And John Cena was undone by a real champion on Monday night when he met a 7 year-old cancer survivor at the season premiere of WWE Raw.
Speaking from inside the ring, the WWE fighter spoke about the bravery of his young fan Kiara Grindrod to the rapturous roars of the crowd.
We've got a special fighter in the house. She has been fighting quite a tough battle, and I'm proud to announce that she won. I sincerely want to thank you for being our guest tonight and for being an inspiration to us in the ring and to everyone else around the world
After completing the speech, Cena and fellow wrestler Sting (Steve Borden) went into the crowd and hugged the young girl in a touching embrace. Cena then gave her his wristband and Sting offered her his glove to the chorus of 'This Is Awesome' in the crowd.
