You’ve seen the face paint. You’ve heard the explosions. Maybe you’ve even bought the lunchbox or the branded casket. But when people ask who are the members of KISS, the answer isn't just a simple list of four names. It’s a decades-long saga of ego, addiction, brilliant marketing, and rock-and-roll survival.
KISS isn't just a band. It's a corporation.
Most people can name the "Demon" and the "Starchild." Gene Simmons and Paul Stanley are the bedrock. They’ve been there since the gritty NYC club days of 1973, through the disco era, the "unmasked" years, and the final avatar-fueled farewell. But the lead guitarist and drummer positions? Those have been a revolving door of talent, resentment, and eventually, stable professionals.
The Original Four: The Lightning in a Bottle
In the beginning, there were four guys from Queens and the Bronx who wanted to be the Beatles on steroids. This is the lineup most purists care about.
Gene Simmons (The Demon) played bass and breathed fire. Born Chaim Witz in Israel, he became the marketing mastermind of the group. Paul Stanley (The Starchild) was the frontman with the soaring vocals and the rhythmic heart. Together, they formed a partnership that has outlasted almost every other duo in rock history, even if they’ve occasionally driven each other crazy.
Then you had the "spaceman," Ace Frehley. Honestly, Ace provided the danger. His guitar smoking during solos wasn't just a gimmick; his playing style influenced an entire generation of guitarists, from Dimebag Darrell to Tom Morello. And finally, Peter Criss (The Catman). He brought a jazz-influenced swing to the drums and sang "Beth," the band’s biggest-ever hit.
It was perfect. Until it wasn't.

By 1980, the wheels were coming off. Peter Criss was struggling with substance abuse and the physical toll of touring. He was essentially fired during the recording of Unmasked, though he appeared on the cover. Ace stayed a bit longer, but by Creatures of the Night in 1982, he was mentally checked out. The band was losing its identity, and the makeup was starting to feel like a prison.

When Peter left, they found Eric Carr. He took on "The Fox" persona. Eric was a powerhouse. He played harder and faster than Peter, helping KISS transition into the heavy metal landscape of the 80s. Fans loved him. He stayed with the band through their "unmasking" in 1983 until his tragic death from heart cancer in 1991.
The guitar slot was messier.
- Vinnie Vincent (The Ankh Warrior): He was a brilliant songwriter but a nightmare to work with. He helped save the band's career by co-writing much of Lick It Up, but his shredding style didn't always fit the KISS vibe. He was gone within two years.
- Mark St. John: He played on Animalize. His tenure was the shortest in band history because he developed reactive arthritis and couldn't play.
- Bruce Kulick: The "no-makeup" guitarist. Bruce brought stability. He wasn't a character; he was just a phenomenal musician who stayed from 1984 until the original reunion in 1996.
If you grew up in the 80s, Bruce and Eric Carr were "your" KISS. They didn't need the paint to prove they could play.
Who are the members of KISS today?
After the massive 1996 reunion tour with the original four, things eventually devolved back into the same old conflicts. Peter and Ace couldn't maintain the pace. Gene and Paul wanted a machine that ran on time.
This led to the "modern" lineup, which actually lasted longer than the original one.

Tommy Thayer took over the Spaceman role. This was controversial. Some fans hated that he wore Ace's makeup. But Tommy had been the band's tour manager and archivist; he knew the parts better than Ace did at that point. He was the "reliable" Spaceman.
Eric Singer stepped back into the Catman boots. Eric had actually joined the band in the early 90s after Eric Carr passed away. He’s a world-class drummer who has played with Alice Cooper and Black Sabbath. He brought a precision to the live show that the band had lacked for years.
So, for the last two decades of their touring life, the members were:
- Paul Stanley
- Gene Simmons
- Tommy Thayer
- Eric Singer
Why the Makeup Matters (and Why It Causes Fights)
You might wonder why Tommy and Eric wore the old makeup instead of creating new characters like Eric Carr did with the Fox.
Business. Pure business.
Gene and Paul own the trademarks to the Demon, Starchild, Spaceman, and Catman designs. They realized that the "brand" was more powerful than the individuals. By putting the new guys in the classic makeup, the "show" stayed consistent. It allowed KISS to become an entity that transcends the humans behind the masks.

This is also why the band can continue as digital avatars. They recently announced that while the physical humans are retiring from the road, "KISS" will live on as high-tech projections created by Industrial Light & Magic.
Understanding the Legacy Beyond the Roster
To really understand who are the members of KISS, you have to look at the contributions of the "ghost" members too. Guys like Bob Kulick (Bruce's brother) played guitar on studio tracks when Ace was too incapacitated to show up. Songwriters like Desmond Child helped them write "I Was Made for Lovin' You."
The band is a collective effort.
Ace Frehley’s sloppy, bluesy brilliance gave them their 70s swagger. Eric Carr’s thunderous double-kick gave them 80s relevance. Bruce Kulick’s technical proficiency gave them 90s credibility. And Tommy Thayer gave them the stability to finish their career on their own terms.
Key Takeaways for Fans and Researchers
- The "Big Four" are Gene Simmons, Paul Stanley, Ace Frehley, and Peter Criss.
- The "Stability Era" featured Bruce Kulick and Eric Carr during the non-makeup years.
- The "Final Lineup" consists of Gene, Paul, Eric Singer, and Tommy Thayer.
- The Avatars represent the future, where the "members" are digital assets owned by Pophouse Entertainment.
If you’re looking to dive deeper into the history of the band, don't just stick to the Greatest Hits. Listen to Creatures of the Night to hear the transition in their drumming style, or Revenge to hear the band at their heaviest without the masks.
The best way to track the evolution of the lineup is to watch the "Kissology" DVD sets. They show the raw energy of the early years versus the polished, stadium-filling spectacle of the later eras. Pay close attention to the 1995 MTV Unplugged session—it's the rare moment where the past and then-present members shared the stage, and it remains one of the most honest moments in their long, loud history.
Check out the official KISS website for the archival timeline, but take the "official" narratives with a grain of salt; every former member has their own version of the truth.
