George Valizadeh, 4, suffers from rigid spine syndrome, a condition causes his muscles to weaken and waste.
Diagnosed aged one, he has been using the wheelchair more regularly and his Mum Ellena was determined to bring some spooky smiles to his face for October 31.
She said: “We wanted George to be excited about Halloween again this year, so I talked to him, and his younger brother, Arlo, about dressing up as their favourite superheroes, Batman and Robin.
“They loved the idea, and my husband got to work straight away, transforming his wheelchair into a Batmobile.
“The boys absolutely loved trick or treating, they ended up with buckets full of goodies.
“All our neighbours were asking George about his Batmobile and were interested to find out about his condition.”
His chair was painted with a black, red and yellow colour scheme, complete with Batman’s logo for the evening.
The theme was particularly meaningful for the south-east London family because when Ellena and her husband talk to George about his condition and medical aids they call them his “superhero power”.
“Talking this way, allows George to understand how he is different to other children and it helps us look at things positively,” said Ellena.
“We’re already thinking about next year’s Halloween costumes.”
