The newborn in Alien: Resurrection. It's a slimy, hideous, bipolar abomination hybrid of human and alien... but who wouldn't fall for those eyes◊?
Alien: Covenant takes this trope one step further with the birth of the chestburster that comes out of Oram: Not only does it look like a tiny little Xenomorph instead of its usual form, but it also mimics David's actions not long after being birthed. And to add icing on the cake, this scene is set to music that is actually heartwarming rather than terrifying.
The toy rabbit that Scott gives his daughter, Cassie, in Ant-Man. It's got a rather uncanny, creepy appearance, but her reaction says it all:
Frankenstein's Monster as played by Boris Karloff, especially in Bride of Frankenstein. There are several scenes that make him seem innocent or sad, such as when he plays with a little girl or when he befriends a blind hermit.
Carrie White in Carrie (1976) qualifies. Just have a look at her when she's in her jammies right before Momma gets stabby.
For some, Both the scarred and un-scarred versions of Chucky the killer doll from the Child's Play series, it helps that he is essentially an evil looking baby doll
The Crites from the Critters series they look like little wide eyed porcupines with fangs, but they have those quills and fangs for a reason and you really wouldn't want one for a pet.
Wikus: (trying to get him to hide from danger) Do you want to play hide and seek? Christopher's son: (looking as delighted as a bug face can) Yes! Yes!
Fizzgig and the Podlings from The Dark Crystal. Heck, we could probably include a lot of Muppets on this list, especially the "darker" Muppets.
All of the goblins from Labyrinth, for example — also, Ludo.
Harry could qualify. He surely isn't conventionally cute, but his fluffy blond hair, lack of maturity and Azure-colored eyes make him absolutely adorable. He actually has a surprising amount of girls who believe he's cute, even downright sexy.
Even Lloyd could be considered this with his chocolate-brown eyes and chipped front tooth along with his overall round face.
Jason Voorhees. It's mostly in the way he tilts his head sideways when confused, though some claim it's the eyes.
Michael Myers fits this trope too. The actor who plays Michael in the brief unmasking scene in the first film was even hired because of his "angelic face."
In the spinoff series' The Real Ghostbusters and Extreme Ghostbusters, it appears he got hit with the adorably ugly stick a bit harder than normal and became more and more conventionally cute... and annoying.
In real life, Mothra would be horrifying. Next to the reptilian kaiju of her universe, she's good-looking enough to be used for Beauty Equals Goodness.
The Mothra larvae look like lumpy brown worms but are every bit as adorable as their mother.
Sure, he's a horrible ancient monster with razor sharp fangs and horns, but those floppy ears make Baragon◊ simply adorable. He has been described as being like a giant puppy quite a few times on the internet.
King Seesar◊ who is an ugly/cute Shisa (A lion-dog creature from Okinawa folklore).
Oddly enough, Godzilla himself during the later Showa films, mostly due to being more kid-friendly around the time. Also, the design of the suit is constantly changing; in the late 1960s and 1970s, Godzilla was overall much cuddlier than he was when he first showed up. Compare Godzilla from 1954 to him 20 years later◊. The nuclear radiation in his body apparently mutated him into Cookie Monster and then into Kermit the Frog.
The MUTOs in Godzilla (2014) can get this reaction from some people, especially when the two of them nuzzle each others face after meeting up in San Francisco.
Godzilla's first land form in Shin Godzilla is this big, dumpy, fishy Godzilla with tiny arms and big eyes. It's so adorable as it rampages through a busy street and demolish anything and crush anyone in its path. Fans have given it the endearing nickname "Kamata-kun", for the Tokyo district where it first came ashore.
The Wargs, being overgrown, snarling canines used by the Orcs, comes off as weirdly cuddly to many fans.
Also, Gollum. Despite his disheveled appearance, violent outbursts and obsession with the One Ring, his expressive face and childlike enthusiasm makes him downright precious to viewers.
Most of the dwarves from The Hobbit trilogy. Those who aren’t already conventionally attractive tend to have rather goofy or brutish appearances, yet their numerous quirks and loyalty to each other makes them endearing company throughout the trilogy.
Despite the tumors and perpetual chapped lips, Nux the War Boy in Mad Max: Fury Road has an odd boyish cuteness about him. The Innocent Blue Eyes help.
In The Man Who Fell to Earth, Tragic Hero Thomas Jerome Newton (David Bowie) is Moe on the outside via a disguise, and this on the inside. One blog commenter described the true form (which is also hairless, earless, fingernail-less, etc.) as "Voldemort with a nose", and in the film it horrifies his human mistress to the point of Bring My Brown Pants. Granted it's a sudden reveal so shock factors into her reaction, but his eyes have just the faintest sheen of pain in them. Gentle-hearted YouTube commenters have compared him and his family (seen in flashbacks), in their white bodysuits, to teddy bears instead.
Men in Black: "Congratulations Reg, it's a...squid." It's the big eyes and the very adorable tentacle-sucking.
J: He's actually kind of... [baby throws up on him] ...cute.
And fitting a real life example, Frank the Pug. (And not coincidentally, such dogs are very popular among fans of the franchise.)
Michael Berryman◊, who has hydrochotic-extodermal dysplasia (a rare condition which prevents him from having any nails, sweat glands or hair), is definitely never going to qualify for being Hollywood Homely, but he seems to have this trope going for him. Even in movies where he plays a bad guy, that baby face of his really might make you want to give him a hug. Of course, it probably doesn't hurt that more often than not, he's also The Woobie in whatever part he's playing.
The title character of Paul. He's a swollen-headed alien with huge adorable puppy dog eyes.
The psycho-killer penis in Russ Meyer-homage, Pervert!
Trumpy from Pod People. As bad as the film is, you have to admit that this is one cute looking alien.
Robert in Rubber. He's a serial killer tire but is oh so adorable.
Space Jam gives us the adorable Nerdlucks. Tiny aliens with squishy bodies and big, goofy eyes who work for the villainous Mr. Swackhammer.
Pretty much all stages of Dren in Splice, although the earlier ones more so than the largely humanoid-looking "adult" stage. Even Fred and Ginger qualify.
Check out the Wookieepedia pages for the Rancor◊ and Wampa◊. Both have artwork depicting a mother of the species cuddling her cubs. You cannot possibly look at the baby Wampas and Rancors without going AWWWWWW!!!!
Many fans find the small size and child-like demeanours of the Jawas to be quite endearing.
YODA. When 900 years old you reach, look as ugly cute you will not. Hmmm?
Cooper, the alien from Super 8. Look at those eyes and try to say you didn't melt in the end.
In Teenage Mutant Ninja Turtles (2014), the turtles' faces have invoked a surprisingly more human appearance than one might expect, leading many fans to find the turtles cute in the most grotesque of ways.
