Young heroes, Javonte Leung, 6, and Ryan Morales, 9, are busting myths about haemophilia
Both boys who are keen on their sports have inherited the genetic blood disorder, haemophilia, which causes blood not to clot properly.
With their condition they have battled bloody joints, bleeds, had numerous visits to The Children's Hospital at Westmead and have constant needles to manage their incurrable condition.
These boys want to show their friends, family members and others with the disorder that they can live a normal life, and run and play like every other child their age.
They will do this through a comic book called Medikidz Explain Haemophilia.
It will take the illustrated look-a-likes of Javonte and Ryan on an adventure with the the Medikidz superheroes, and will teach children and their families about haemophilia and how to care for the condition.
Javonte was diagnosed with haemophilia when he started walking and experienced severe bleeds.
There is no known history of the genetic disorder in his family and both his parents have had a lot to deal with when learning about it.
Javonte's mum Pierrta Leung said she was proud her son could help others.
"He has been through a hell of a lot and he is still smiling every day," Mrs Leung said.
"If we can bring that to other people that would be lovely."
Ryan was diagnosed at three-days-old and is now starting to learn how to give himself injections and manage his own treatment.
Ryan said he will be able to read the comic to his little brother, Thomas, who has been recently diagnosed with the blood disorder.
"I'm excited because I get to teach Thomas about haemophilia as well as my friends," he said.
"They don't know what haemophilia is and they keep asking me.
"I can teach them about it with the comic book."
