The special message was inspired by Aiden’s mother, Sarah, who described Reynolds as a “good friend”.
“Ryan appreciated everyone that helped get Aiden through his darkest days and was very happy to do a shout out,” she added.
Aiden’s ashes were scattered on Wrexham’s pitch after his death and the family were presented with a tribute.
Katie Southgate, the founder of Gold Geese, said she “couldn’t believe” it when she saw Reynolds’ message.
“Aiden was an absolute legend of a person. He was kind and funny and really into his gaming and loved Wrexham AFC,” she said.
“I know he would have absolutely loved to see my jaw drop when I got a video message from Ryan Reynolds.”
“Aiden’s legacy and memory live on, forever,” she added.
