Kiss founders Gene Simmons and Paul Stanley recently compared their former bandmates Ace Frehley and Peter Criss to cancer, and Frehley has hit back.

One of Simmons' biggest criticisms of Frehley and Criss is that they are "losers" who are "drunks and alcoholics" who consistently make "wrong decisions."

"Gene's living in the past," Frehley said. "He's become a caricature of himself. I mean, from the very beginning, his only motivation was money. The guy has no friends."

"He's not respected by his peers," Frehley continued. "He's pissed off thousands of fans. ... He's never had a hit single, like I've had. I had the most-successful Gibson signature-series guitar in history. He didn't. It goes on and on."

All four members of Kiss have released solo album's, and Frehley's New York Groove reached number 13 on the Billboard Hot 100 chart in 1978.

Simmons said Frehley and Criss were a "cancer in your system" which must be cut out "as fast as you can."

Frehley mocked Simmons for not living the lifestyle of a rock star.

"[Gene] took the safe route," Frehley said. "He never got loaded, he never partied. I took the same route as Elvis Presley took and [Jimi] Hendrix and Keith Richards and Jim Morrison. I have all this life experience, and thank God I can live to talk about it. What's he gonna talk about? All he can do is badmouth other people."
