When the "Samoan Bulldozer" Umaga passed away in 2009, he left behind a terrifying legacy in the ring and a massive void in the Anoa'i family. For years, fans wondered if any of his children would pick up the mantle. Well, that answer arrived loud and clear in the form of a young man named Zilla Fatu.
Honestly, if you haven't been keeping up with the independent wrestling scene lately, you’ve missed one of the most intense redemption stories in the business. Zilla Fatu isn't just another name on a family tree. He’s the fourth son of Edward Smith Fatu (the man we knew as Umaga), and his path to the squared circle was anything but a straight line.
Why Everyone is Talking About Zilla Fatu
If you search for who is umaga son, you’re going to find Zilla’s name everywhere. Born Isayah Fatu, he is currently the most visible of Umaga’s children, but his life didn't start with championship belts. At just 15 years old, while most kids were worrying about homework, Zilla was facing a six-year prison sentence.
He was charged with aggravated robbery. He spent those formative years in the Texas State Penitentiary. It’s a heavy backstory. You’ve gotta respect the fact that he doesn't hide from it. In interviews, he’s been pretty open about how being "lost" led him to that point. But prison was also where he found Islam and decided to flip the script on his life.
The Training Ground: Reality of Wrestling
When he got out in 2022, he didn't just walk into a WWE contract because of his last name. He went to Houston. He called up Booker T.

Training at Booker’s "Reality of Wrestling" (ROW) school is sort of a rite of passage for many in the family now. It makes sense. Booker T and the Fatus go way back. Zilla’s debut in July 2023 was a massive viral moment. He walked out, looked exactly like a leaner version of his father, and won his first match in minutes.
But it wasn't all sunshine and rainbows. Within months, he was out of ROW due to "irreconcilable differences." In the wrestling world, that’s usually code for a clash of egos or a disagreement on how fast someone should be pushed. Kinda standard stuff for a young guy with a legendary name. Luckily, they patched things up, and by 2024, he was back in ROW and eventually captured their Heavyweight Championship.
Making Waves in 2025 and 2026
The momentum didn't stop in Houston. Zilla has been tearing through the indies like a man possessed. He’s worked for Game Changer Wrestling (GCW) and House of Glory (HOG). In HOG, he’s held the Crown Jewel Championship, even going toe-to-toe with veterans like Bully Ray.
By the time we hit 2025, his name was being whispered in the same breath as TNA and WWE. He actually made a high-profile appearance at TNA’s Slammiversary 2025, teaming up in a six-man tag match. It showed the world that he could handle the bright lights of a major broadcast.

The question isn't if he’ll be on a major TV show every week—it’s which one.
The Bloodline Connection: Roman, Solo, and the Spike
You can't talk about who is umaga son without mentioning the elephant in the room: The Bloodline.
Since Roman Reigns and Solo Sikoa turned the WWE into a family drama, every Anoa'i family member is under a microscope. Solo Sikoa actually uses the "Samoan Spike" as his finisher now. Zilla has some thoughts on that. He’s publicly stated that he sides with the "Original Tribal Chief" Roman Reigns.
There’s a bit of real-life friction there, too. Zilla mentioned in a Busted Open Radio interview that he’s been "beefing" with Solo since they were kids. He even joked about giving Solo his first Rock Bottom in a swimming pool when they were eight. Seeing Zilla debut in WWE to challenge Solo for the "rights" to their father's finisher is a storyline that basically writes itself.

Is he the only son?
Actually, no. Umaga had four children with his wife, L.T. Fatu. While Zilla (Isayah) is the one in the headlines, he has siblings, including an older brother also named Isayah (it's a family thing) and others who stay out of the public eye. But in terms of the wrestling business, Zilla is the one carrying the torch.
What's Next for the Son of Umaga?
If 2026 is the year Zilla Fatu finally lands in NXT or on the main WWE roster, the landscape changes. He has a specific "aura"—as the kids say—that you can't teach. He’s got the tattoos, the intensity, and that terrifying stare that made Umaga a Hall of Fame-level talent.
The cool thing about Zilla is that he isn't trying to be a 1:1 copy of his dad. He’s more athletic, he talks on the mic, and he’s incorporating his own life experiences into his character. He calls himself the "Main One."
If you want to follow his journey, keep an eye on independent shows in the Texas area or check out his social media. He's very active in documenting his training. The best way to support him is to watch his matches on streaming services like TrillerTV (formerly FITE) where his GCW and HOG matches live. The hype is real, and honestly, the "Samoan Bulldozer" would probably be pretty proud of the way his son turned a prison cell into a championship ring.
The logical next step for any fan is to go back and watch Zilla’s debut match at Reality of Wrestling. It’s on YouTube for free. You’ll see the moment the crowd realizes they aren't just watching a tribute act, but a future superstar in the making.
