Godzilla will stomp its way into U.S. theaters in about a month when the Gareth Edwards-directed reboot of this classic movie monster franchise debuts on May 16. Although Godzilla made his first appearance in in the original Gojira film as a one-monster act, Japan’s Toho Studios later released dozens of sequels that pitted the mutated reptile against various other giant monsters, or “kaiju.” Godzilla’s onscreen opponents included everyone from Mothra — a giant flying moth creature – to Mechagodzilla – a robotic counterpart to Godzilla. However, one of Godzilla’s most famous opponents – King Kong – was already a star in his own series of films.

Although the new Godzilla film appears to be an homage to the original film in which Godzilla only has to worry about fighting humans and their weapons of mass destruction, we can’t help but wonder what contemporary movie monsters the latest Godzilla incarnation might battle in future crossover sequels. Excluding rebooted movie monsters that have already fought Godzilla – such as King Kong – here are five recent movie monsters that we would love to see go toe-to-toe against the “King of the Monsters.”

1. Smaug from The Hobbit: The Desolation of Smaug (2013)

The gold-loving dragon from Peter Jackson’s second installment in The Hobbit trilogy would definitely make an interesting opponent for Godzilla. Not only could Smaug attack Godzilla with his fiery breath, the Benedict Cumberbatch-voiced dragon could also deliver equally scorching sarcastic comments. Think this matchup is too ridiculous? Then you obviously haven’t seen Godzilla fight King Ghidorah, the three-headed armless dragon.

Although moviegoers only got a glimpse of Smaug’s destructive power in The Hobbit: The Desolation of Smaug, fans who are familiar with the J.R.R. Tolkien novel know that even more fiery destruction will be unleashed in the final film in the trilogy, The Hobbit: There and Back Again, that is scheduled to be released this December. However, don’t hold your breath for The Hobbit–Godzilla crossover.

2. Jaegers or Kaijus from Pacific Rim (2013)

Not surprisingly, this Guillermo del Toro-directed tribute to classic Japanese “kaiju” movies has plenty of giant-sized creatures that would make excellent Godzilla movie costars. Any of the alien Kaiju creatures or the giant, human-piloted mechanical Jaegers would make worthy opponents for Godzilla to fight. Del Toro even discussed the possibility of a Pacific Rim–Godzilla crossover during an interview with Collider last year. “I would love to see a jaeger and Godzilla duke it out,” the Pacific Rim director told Collider. “That would be too much for the human brain.”

Unfortunately, del Toro also made it clear that there were no plans for that dream mash-up. However, a Pacific Rim 2 is looking more and more likely. According to ShockTillYouDrop, Legendary Pictures – the studio behind Pacific Rim and the new Godzilla – is still “open” to a Pacific Rim sequel.

3. Giants from Jack the Giant Slayer (2013)

This movie based on the “Jack and the Beanstalk” fairytale features a literal army of monstrous giants that would make ideal opponents for Godzilla. However, like many of these wishful movie mash-ups, the battle between an atomic bomb-spawned lizard and magical sky-dwelling giants is unlikely to ever be seen outside of our overactive imaginations for multiple reasons.

According to Box Office Mojo, Jack the Giant Slayer was phenomenal financial flop with a total domestic lifetime gross of only $65 million after costing the studio an estimated $195 million to produce. It’s unlikely that any studio would ever want to hitch the Godzilla franchise to a known money-loser like Jack the Giant Slayer. Not to mention the complete lack of any overlap between the world of Jack the Giant Slayer and the world of Godzilla. But, hey, we can still dream, right?

4. Kraken from Clash of the Titans (2010)

To paraphrase a famous line from Clash of the Titans, “Release the Godzilla vs. Kraken movie!” Sure, we know there’s a complete lack of overlap between the Greek myth-based world of Clash of the Titans and the atomic age world of Godzilla. However, when it comes to giant monster battles, we could care less about storyline consistency – we just want to see two oversized reptilian creatures slug it out off the coast of Greece or Japan.

5. Unnamed monster from Cloverfield (2008)

Unlike the Kraken from Clash of the Titans or the race of giants from Jack the Giant Slayer, the gigantic creature from Cloverfield would appear to mesh perfectly with the world of Godzilla. This is probably because J.J. Abrams – the producer of Cloverfield – was inspired by the original “King of the Monsters.”

“I was in Japan with my son and all he wanted to do is go to toy stores,” Abrams told the audience at Comic-Con 2007, according to FirstShowing. “And we saw all these Godzilla toys, and I thought, we need our own monster, and not King Kong, King Kong’s adorable. I wanted something that was just insane and intense.” The result was the “found footage” monster flick Cloverfield. Although it’s unknown how the current Godzilla movie will end, it was also not clear if the creature in Cloverfield was ever successfully killed by the military’s bombs. The open-ended conclusion of Cloverfield may make this movie monster the most sensible candidate for a battle against Godzilla.
