UPDATE: 5-year old Spider Boy has Passed Away (Dad surprised his Son as Spider-Man that went Viral)

From the Daily Mail:

A cancer-stricken boy who became an internet star after his father dressed up as his fictional hero, Spiderman, to cheer him up has died peacefully in his sleep.

Jayden Wilson died at home in Basingtstoke, Hampshire, on Christmas Eve with his parents and sister nearby.

The five-year-old had been battling a brain tumour for more than a year.

Last month he became an internet star when his father shared a video online of himself dressing up as Spiderman to surprise his son on his fifth birthday.

Yesterday his parents paid tribute to the child they described as 'the most inspiring person ever'.

Writing on the family's Facebook page, Mike Wilson said: 'Late on Christmas Eve, Jayden passed away peacefully in his sleep, warm in his bed.'

R.I.P. little Spidey.
