These 3 creatures are the archetypal monsters of the land, sea, and air in the Bible, and I think that the All Stars’ Awakening forms will be a reference to these. First off, it makes sense for all of the All Stars to have Awakening in order to distinguish themselves from the Tobi Roppo. In Kaido’s crew, Oda uses DF classes to separate the BPs into tiers. The Gifters and headliners having SMILEs distinguishes them from the Waiters and Pleasures. The Tobi Roppo having Ancient Zoans distinguishes them from the Gifters and headliners. Kaido having a Mythical Zoan distinguishes him from the All Stars. So it would make sense for the All Stars to have Awakened Ancient Zoans in order to distinguish them from the regular Ancient Zoans in the Tobi Roppo.
In ancient times, Behemoth was depicted as a giant bull, but modern interpretations (mainly from the Kaiju series, created in Japan), basically just depict Behemoth as a giant Mammoth on steroids:

King would match up with Ziz for obvious reasons:

Queen as Leviathan is the one that requires the most mental gymnastics. The problem is that Oda probably doesn’t want to make aquatic Zoans because they wouldn’t be useful on land, and then it would raise the question of how an aquatic Zoan DF would work in the water, given the weakness of DFs. However, Queen’s Zoan form does look like another aquatic monster, the Loch Ness Monster:

The Brachiosaurus looks pretty much like a land version of the Loch Ness Monster, so maybe Oda is using that as a stand-in for the Leviathan, and Queen’s Awakened form will look more “monstrous” than the Loch Ness Monster, and a little bit more like the Leviathan
