Ziana: It should as no surprise that Destoroyah possesses the power of the Oxygen Destroyer given his mutation. He can absorb your DNA and add it to his own, which is why he took Godzilla and Junior's DNA to make himself more powerful. He can fire Micro-Oyxgen Beams that can vaporize most organic matter and even melt metal.
Kira: Destoroyah also has the ability to split into smaller Kaijus to overwhelm an opponent or fuse into one strong monster such as his Aggregated, Flying and Final Forms. He can charge up his Horn Katana to deliver deadly cuts or just drag you around with his pincer tail whenever he flies.
Zen: And being a crustacean doubles as a bonus as Destoroyah is covered head to to in tough armor, capable of shrugging of most physical attacks. And while it cut from the movie, Destoroyah's strongest move is his Oxygen Destroyer Chest beam, which has been shown to knock Godzilla down while cutting a part of his tail and several spikes.
Kira: Oh and fun little fact, the directors of the movie stated Destoroyah's Perfect Form is actually isn't his final one, as he can continually grow by absorbing more DNA if given the chance.
