How Fast Is the Deep in ‘The Boys’? Here’s Just How Fast Vought’s Least Respected Supe Can Swim!

When ‘The Boys‘ introduced Kevin Moskowitz to the world, it gave audiences something they never knew they wanted: a deeply insecure, gill-bearing parody of one of DC’s most mocked superheroes. Played by Chace Crawford across all five seasons of the Amazon Prime Video series, The Deep was marketed by Vought International as a supreme aquatic powerhouse, even starring in an Olympics-style promotional ad as “the greatest swimmer of all-time.” The reality, as the show so gleefully reveals, is a little more complicated.

Understanding exactly how fast and powerful The Deep really is requires cutting through a lot of Vought corporate spin. The character’s primary powers consist of talking to sea creatures, being an expert swimmer, and breathing underwater thanks to his gills, but the show has always been deliberately vague about pinning down the hard numbers behind his abilities. That ambiguity has fueled one of the most entertaining ongoing debates in the show’s fandom.

The Deep’s Superhuman Swimming Speed Explained

The clearest on-screen demonstration of The Deep’s raw swimming capability comes not from the man himself, but from the marine life he controls. A sperm whale under his command was easily able to overtake and pass a speedboat, which is ordinarily highly unlikely given that sperm whales have a natural top speed of around 45 km/h, or approximately 28 miles per hour.

The implication is that The Deep’s enhancement of these animals pushes them well beyond their biological ceiling, and his own swimming capacity likely operates in a similar tier.

Beyond that whale sequence, the wiki record of his feats supports a speed level that is impressive but grounded in tactical utility rather than jaw-dropping spectacle. His swimming speed is quick enough to reach the back of a dock before Starlight could reach the entrance, and he managed to swim across a harbor and out to an ocean crash site to scour Flight 37 wreckage for blackmail material.

These are not the exploits of someone moving at the speed of light, but they are genuinely superhuman feats by any real-world measure.

He can swim at impressive speeds seemingly without tiring or needing to come up for a breath, courtesy of the gills on his lower torso. That endurance factor is arguably just as important as his raw velocity, because it means he can sustain his aquatic pursuit or evasion over distances that would be physically impossible for any unenhanced human swimmer.

What the show deliberately avoids is attaching a specific mile-per-hour figure to his underwater movement. Even the ‘Boys’ wiki states that the full extent of his abilities is essentially breathing underwater, adept swimming, above-average land-based strength, and the ability to talk to and coerce marine life. In a show where A-Train runs at supersonic speeds, The Deep’s ceiling reads as modest by comparison.

The Deep vs Aquaman: A Power Gap Hiding in Plain Sight

The comparison to DC’s Aquaman is built directly into the character’s DNA, and the show never lets audiences forget it. The Deep is The Boys’ version of Aquaman, and similar to his DC counterpart, he can breathe underwater, swim at super speed, and communicate with sea life. That surface-level parallel is where the resemblance largely ends, though.

The Deep even suffers from an inferiority complex, which is a pointed jab at Aquaman’s own relatively awkward powers compared to many of his superhero contemporaries. Chace Crawford himself has leaned into the parody with genuine enthusiasm.

In an interview with GQ, Crawford revealed that Aquaman fans occasionally send him angry messages on Instagram saying things like “F–k you, fish guy. You think it’s funny to make fun of Aquaman?” to which the actor’s response was simply “Perfect. That’s exactly what I want.”

While both characters share the ability to live underwater and communicate with fish, ‘The Boys’ takes things a step further by giving The Deep gills on his torso and making his interactions with aquatic life oddly sexual, which is entirely on-brand for a show that never misses an opportunity to skewer its superhero archetypes.

The Deep’s Powers on Land and His Critical Weaknesses

The Deep’s power ranking drops dramatically the moment he leaves the water, and this is a crucial part of understanding his overall threat level. When removed from his aquatic domain, his strength diminishes considerably, and while he still possesses superhuman durability and some degree of enhanced strength, he loses his primary advantage in mobility and his unique command over marine life.

He appears to be by far the weakest member of The Seven overall, with Starlight able to shrug off .50 caliber bullets and bench press a car, Maeve capable of stopping a speeding semi-truck effortlessly, and A-Train running at supersonic speeds. The Deep’s physical toolkit, while genuinely beyond human capability, simply does not stack up when placed alongside the rest of his former team.

His most exploitable physical vulnerability is tied directly to his greatest asset. The gills that give him his underwater breathing ability also serve as an extreme weakness, as they are highly sensitive and anything going inside of them causes intense pain. Beyond his physical limitations, his psychological state is a major impediment to his effectiveness, with a tendency toward depression, addiction, and a desperate need for external validation.

A Supe Built for the Sea, Stranded on Shore

Ultimately, The Deep is a character whose powers are perfectly suited for a world that barely needs them. Compared to a speedster like A-Train or a strong warrior like Queen Maeve, The Deep may seem like the weakest supe in ‘The Boys’ with his abilities to breathe underwater and talk to marine life. That gap between his perceived status and his actual capability is precisely what makes him one of the show’s most tragicomic figures.

After earning the wrath of his aquatic friends several times over and goading longtime rival Annie January, the sniveling Deep refused one last chance for redemption in the series finale and was ultimately thrown into the sea to become fish food.

It was poetic in the most brutal way possible, and entirely consistent with everything the show had built around him. The Boys imagines a version of reality where superheroes are real and meditates on the psychosocial implications of that, reaching often disturbing but always fascinating conclusions, and no character embodies that meditation more completely than The Deep.

Whether you think his watery ending was the perfect send-off or a wasted opportunity to finally show him at full power underwater, drop your take in the comments, because the debate over what The Deep was truly capable of is one ‘The Boys’ fandom may never fully resolve.
