Spin-offs

The Clash of the Titans tour has spawned at least two spin-off tours. Three-fifths of the European lineup (Megadeth, Slayer and Testament) were reunited on the American Carnage Tour that took place from July to early September 2010.^[8][9] This was followed shortly by a second leg of the tour that featured three-fourths of the North American lineup of the Clash of the Titans tour: Megadeth, Slayer and Anthrax.^[10]

A similarly titled tour Klash of the Titans took place during the spring of 2023, with Kreator as one of the co-headliners to both of them. The first leg took place in Latin America and featured Kreator and Testament,^[11] followed shortly by a North American leg that was co-headlined by Kreator and Sepultura and included support from Death Angel and Spiritworld.^[12]

Possible revival

On December 9, 2017, Ultimate-Guitar.com reported that a rebooted Clash of the Titans tour featuring Megadeth, Slayer, Testament and Sepultura was in the works, and scheduled to take place in 2018 or 2019 in support of new albums from these four bands.^[13][14] More speculation about a tour similar to Clash of the Titans was renewed in January 2018, when Megadeth frontman Dave Mustaine mentioned a potential tour featuring Exodus and three of the "big four" (Megadeth, Slayer and Anthrax);^[15] a month later, Mustaine tweeted another potential tour similar to Clash of the Titans, titled "The New Big 4", featuring Megadeth, Anthrax, Exodus and Testament.^[16]

When Slayer announced their farewell tour in January 2018, it was suggested that the recently rumored Clash of the Titans tour (also featuring Megadeth, Sepultura and Testament) would take place as part of the aforementioned tour.^{[17][18][19][20]} Although Mustaine cryptically denied that this tour was in the works,^[21] he stated in a June 2018 interview with Rock Talk With Mitch Lafon that, "I hope that Megadeth and Slayer get to go one more round somewhere. I think it would be great, especially if it was a 'Big Four' show, but that's entirely up to them. And if it doesn't happen, we've had our share of Slayer and Megadeth shows, and I'll always appreciate those times together."^[22] Testament frontman Chuck Billy also commented on the tour rumors, referring to Slayer's farewell tour, "I doubt it, this is Slayer's last tour so this is it. There will be no more Slayer tours."^[23]

When asked in August 2018 by CBS San Francisco about the possibility of a revival of the Clash of the Titans tour with Slayer and Megadeth, Anthrax bassist Frank Bello stated, "I wouldn't say it's under wraps because I don't know about it. But I would absolutely love for the Big 4 thing to happen again. That would be the right thing to do for everybody. I would love that. I mean, as far as Slayer goes, I'm sure they're going to do more shows next year, but I don't know if we'll be on them, because we do have our album to write. It's all about scheduling and agents and all that. But we'd be open to any of that, specifically the Big 4. I think all four bands that were involved with the Big 4 would love to do it again. But that's totally up to Metallica."^[24]

In August 2019, the website Metal Addicts reported that a 30th anniversary edition of the Clash of the Titans tour was rumored to be taking place in 2020 and would feature a different lineup, with Megadeth and Testament likely to be included, but added that Slayer was not expected to be on the bill due to their farewell tour, which ended in November 2019.^[25] When asked a month later by The Metal Voice what the odds were for the revival of the Clash of the Titans tour and their European tour with Testament and Exodus—The Bay Strikes Back, Death Angel frontman Mark Osegueda commented: "The revival of the Clash of the Titans one, that's of course out of our hand. I've seen, some rumors floating around everywhere of course, we've not been approached so I could not tell you that, you know, I've heard anything. We've not been approached as a band as far as the Bay Strikes Back to tour that's happening in February–March in Europe."^[26]
