Snakebite drummer Thomas Franke played in 1987 on Animal House, the first solo album by the former Accept singer Udo Dirkschneider. Rittel and Szigeti formed in the 1990s the melodic metal bands Energy and Coracko, without much success. Michael Eurich formed the band Casanova with singer Michael Voss, which was active at end of the 80s. Doro Pesch reunited with Szigeti, Arvanitis, Rittel and Eurich to perform as Warlock at her 20th Anniversary celebration concert in Düsseldorf on 13 December 2003 and later at Wacken Open Air festival 2004.
