WATCH: 'Best dad ever' dresses up as Spiderman to surprise terminally ill son, 5
His dad is one amazing Spiderman.
That's why five-year-old Jayden had the best birthday gift when the superhero (aka dad Mike Wilson in disguise) swung by for a surprise.
Jayden, who is battling from a grade 4 brain stem tumour, seemed stunned when Spidey leapt off the roof and said: "Hey, is that Jayden?"
The webslinger then asked the boy for a hug, after quizzing him on his age.
That's not all: #SuperDad also asked for permission to enter the house in Hampshire, England, so Jayden could tell him more about his birthday.
The video, uploaded on YouTube on Nov 16, has already been watched a staggering 700,000 times.
Besides praise for superdad Mike, people also left well wishes for Jayden's recovery.
Mike said: "Today he is still with us fighting it all the way, but at least he has Spider-Man to take care of him".
Jayden's condition means he has, on average, a year to live.
