Residents of the Houston, Texas, apartment complex where Billy and his parents, Chris and Kelen, live know how much he loves superheroes and Halloween, so they decided to celebrate a few months early.

The main office was turned into a superhero’s dream on Saturday, with people dressed as various characters and the room filled with custom Avengers-themed decorations, which were donated by complete strangers. Meanwhile, the man of the hour came as Iron Man and totally rocked it.

“Billy loved it!” Chris Lee, Billy’s dad, told TODAY.com. “He always loves seeing full-sized heroes like this.”

He was diagnosed with medulloblastoma, an untreatable form of brain cancer, about two years ago and only has a little more than a month left to live.

Billy’s parents, who both quit their jobs to care for their son, created a GoFundMe last month, which helped send him to Florida to see his favorite superheroes and spend time as a family.

“Our overall goal is to make the last days he has as enjoyable and pain free as possible,” Chris wrote on their GoFundMe page. “To give him what every kid wants but rarely gets. If there were ever a child that deserves this, it is our son Billy. After all of the battles he’s had it is finally time for him to relax.”

Their first stop in Florida was to see the Transformers 3-D ride at Universal Studios, which is something he’s been asking to do for a while now.

The family is hanging in there and focusing on how to make Billy’s final days count.

“It’s definitely not easy, but for now we have to take care of him,” Chris told TODAY.com. “We’ll take care of ourselves once this is all done.”
