So, your airship/spaceship/boat/car is already cool as it is. However, it seems to be missing something. How can you make it cooler? With your own self-image, of course! Make your vehicle a Faceship.
A Faceship is any vehicle or ship that has the likeness of a character's face or the entire character built on it, usually its pilot or Captain. Villains have a tendency to use these, either for the purpose of intimidation or due to their huge ego, but heroes can ride in these as well (see image at right for a hero's example). If the design isn't the owner's face real face but the design of their distinctive mask or helmet, it gets a bit more plausible, but it can make it less obvious which came first.
Alternately, instead of a face, the front will be a Skull, for the extra intimidation factor.
Often overlaps with Cool Spaceship, Cool Airship, Cool Boat, or Cool Car. If the face has a mouth that can swallow things, it's a Mega-Maw Maneuver. Villainous versions overlap with Malevolent Mugshot. This is a Subtrope of Thememobile.
Anime and Manga
The ships of Shangri'La in Noein have the form of multi-faced floating statues.
Team Rocket's Meowth Balloon from Pokémon. Also, their Magikarp (originally a Gyarados) submarine.
Great Mazinger: And so did Mykeros and Demonika, Mykene Empire Cool Airships and airborne carriers. Mykeros had multiple faces built along its entire perimeter in reality were gates to launch the Robeasts.
UFO Robo Grendizer: When Grendizer transformed into a Starship, his face appeared situated on the bow. Several Vegan Starships also had a face on the frontside.
While most of the Gunmen in Gurren Lagann are face-shaped, the Anti-Spirals have several spaceship models based on body parts, including faces. It is incredibly creepy. Chouginga Dai-Gurren also counts. It's essentially a huge transforming robot, which spends more of its screen-time as a giant ship. It's ship-form is basically the Space Battleship Yamato with a face slapped onto the front.
Mobile Suit Gundam: Char Aznable's personal Musai-class cruiser has a bridge tower customized to be vaguely reminiscent of his helmet and mask.
In Kingdom Come, Dr. Sivana's head appears in the form of a tentacled faceship similar to Brainiac's, slaughtering the Marvel Family in a movie sequence made to torture a grown-up Billy Batson into submission to Lex Luthor's will.
Batman's Batmobile sometimes has his masked face on it. One time, The Joker decided he should have something like that and created the Jokermobile, which has his face on it.
Vartox's Intergalactic Headship from the pages of Power Girl most certainly qualifies.
The Blitzspear from Nemesis the Warlock - a reverse example, in that the Blitzspear appeared several episodes before Nemesis himself, and the artist decided that when Nemesis himself finally appeared, the face would be based off the car.
Not quite a ship, so much as a spaceship-port, but there's the Knowhere from Guardians of the Galaxy (that is, the 2006 series). It's made out of the severed head of a giant, über-powerful, space-god.
The masks worn by Kamen Rider Den-O's various forms also adorn the cars of the DenLiner train.
The Mask got two in the toyline—the Mask-Mobile and the Mask Cycle. The first is notable for appearing in both the animated series and in Son of the Mask, and the second is a two-for-one Facemobile: its sidecar carries Milo, and has a replica of Milo's grimacing green Mask face on it. Both of these are justified examples of the trope, even for a toy—the Mask can customize an ordinary car or motorbike just by sitting on it!
BIONICLE: The Toa Terrain Crawler's visage is very similar to the Kanohi Faxon worn by Hahli. Being that it's a living creature fitted to be used as a diving vehicle, it's more coincidental than anything.
Saints Row 3 has the "Gatmobile" Which is a big ol van with a Gat head for a front end, usually ridden by a Saints mascot wearing a large Gat mask. It's not unique although you'll probably think it is and it's implied to be one of the parts of the Saints turning into pop-culture icons. Oh and it doubles as the most durable vehicle that isn't a Tank, and as a result, doesn't cause mass panic when it's driven.
In Metal Gear Solid 4: Guns of the Patriots, Snake encounters Liquid Ocelot's base of operations, Outer Haven, which for strange reasons, has the faces of Solidus Snake, Liquid Snake, Solid Snake and Big Boss on it that resemble Mt.Rushmore. It has been nicknamed "Mt.Snakemore".
The Huge Spaceship in LittleBigPlanet 2 looks like the Enterprise with Sackboy's head.
In the opening stage of Star Fox Assault, Andrew (the nephew of the late Emperor Andross) transforms his flagship into a gigantic replica of his head as a homage to the final battle of Star Fox 64, where you fought Andross (who was nothing more than a giant disembodied head and hands).
Charon, the ship that guides damned souls to Hell in Dante's Inferno, has a giant talking head as the figurehead.
The entire race of Lingon in Fig Hunter Universe uses spaceships shaped like their heads.
Several of the historical Cooper family vehicles from Sly 3 Honor A Mong Thieves have stylized Cooper faces in the design, notably the autogyro.
In the Street Pass Mii Plaza game Mii Force, the Gold Bone Gang's entire fleet apparently has this motif, with all of the skull-faced opponents piloting a ship with a skull on it somewhere (including, yes, on their mothership).
Ratchet & Clank: More an occasion of Facestation in A Crack In Time with the Nefarious Space Station that's shaped like Dr. Nefarious' head.
While it's not your head, in a World of Warcraft dungeon you can get a flying helicopter mount of Mimiron's Head, a flying mechanical gnome head.
An very obtuse example in a short on MTV's Liquid Television, called "Space War", that was done to appear like a 6th grader's board doodling of an alien invasion shows the alien's mothership to be a 400 mile tall version of the classic image of what most Westerners think as god's face.
The Petercopter and Hindenpeter in Family Guy has Peter Griffin's head at the front. Also, in an Imagine Spot teaser, Stewie is an intergalactic fighter pilot tasked with destroying a huge Death Star-esque station that is essentially a 3D model of Peter's head. In reality, he's playing with a toy fighter ship and jabbing it into the side of Peter's head as he yells "Die! Die!".
Dr Doofenshmirtz has a monster truck, among other vehicles, shaped like him. Also, Professor Poofenplotz from "Isabella and the Temple of Sap" has her "Me-Mobile", a Spider Tank shaped like her head. A later episode reveals that Poofenplotz also has a "Myself-icopter."
Phineas and Ferb themselves get in on the action with hot air balloons in their own likenesses in "Last Train to Bustville".
Megatron did this twice. First, in Beast Wars, he molded a Vok craft into his face for a few minutes. Then, in Beast Machines, he built a transforming ship with his face permanently on it.
The Larrymobile from VeggieTales, which basically looks like Larry Boy laying on his back with his plunger-ears serving as the back wheels and two more plungers seving as the front wheels located where his legs (if he had such, since Larry Boy doesn't have legs) would be.
But how is he able to drive it if he doesn't have any arms?
Presumably the same way all of the vegetables can manipulate phones, hairbrushes, doorknobs, swords, espresso makers...
One episode of Static Shock had The Joker and his henchmen drive around in a firetruck shaped like his face terrorizing people.
One episode of Cyberchase had The Hacker and his cronies Buzz and Delete enter a race with a large sinister-looking green car with The Hacker's face on the front.
