Oliver Tree’s body has been returned home to the US, a week after he was killed in a fiery helicopter crash in Brazil — with his loved ones sharing how they’re helping his legacy “live on forever.”

“Oliver is now back in California where he can finally rest,” confirmed a message on the “Alien Boy” singer’s Instagram page Sunday along with a montage of snaps paying tribute to the “Life Goes On” artist.

His legacy will live on through his foundation/endowment named ‘Dr. Oliver Tree’s Extremely Epic Grant For Baby Geniuses,'” the message added, teasing it would be “coming soon.”

Thanks to this, the message said, the “Life Goes On” singer’s “legacy will live on forever ❤️.”

The Santa Cruz native – renowned for his bowl-style haircut – had mentioned his dream of leaving everything to a foundation in an April 24 episode of “The Zach Sang Show” in which he said wouldn’t leave his family  “a f–king penny” if he died.

“I don’t believe that any of the wealth, or the things that get made from it, is mine. So when I die, my will is set up that when I pass, my family, no one’s going to get a penny,” he clarified.

“If I have a wife or kids or anything, they’re not getting a f–king penny.

“I’ll get my kids through college. That’s the agreement. But there’s not going to be a silver spoon. The idea is, when I die, all the money is going to go back to artists.”

The singer explained his foundation would go towards creating art.

“It’s set up so that the interest generated from my music, will take mostly that, but there’s also room for other money because when I die, my art will continue to have residuals and probably be worth more than it is now,” he said.

“I want it to go to the actual physical of making art. You’re not allowed to buy equipment with the money. You’re not allowed to go get education and schooling with the money.”

He revealed it would be down to the foundation’s committee how any money would be spent.

Tree’s team said the singer’s legacy “will live on forever,” adding, “Oliver would be so proud of every one of his supporters, friends and family.”

His team shared snaps from throughout the years – including throwback pictures of him playing his guitar as a child and memories from trips to India and Russia.

The singer was killed alongside Argentine influencer Gaspar Prim, Lucas Vignale, Lucas Brito Chaves, and the two pilots Alexandre Souza and Charles Marsillac in the mid-air collision that happened over a Rio de Janeiro electric car lot. 

Aviation authorities in Brazil are probing whether there were issues with radio systems and flight plan irregularities contributed to the crash.

It could take up to five years for the final report to be published.
