Watching the opening cutscene of Lego Batman, This Troper wondered what a perfectly sane catburglar like Catwoman was doing in Arkham Asylum, as opposed to a regular prison. Upon completing her level in the game (at the end of which Batman captures her by putting out a saucer of milk and she just can't resist lapping it up like a cat), he understood: this version of Catwoman thinks she is actually a cat.
In Lego Harry Potter, why can the generic Death Eater pick up Mandrakes, who paralyze people with their screech? Because he's a DEAF eater!
In LEGO Batman 2, every returning villain (except Joker and Scarecrow) is a Degraded Boss. This makes sense when you think about it: in the first game, the villains had a plan to break out, so they already had equipment, gangs, and hideouts ready for them once they escaped. In the sequel, they escaped because Joker and Lex set them loose while escaping to keep Batman busy, so they were completely unprepared.
In Lego Marvel Super Heroes, I was bugged by why the Fantastic Four's Human Torch was in the level "Red HeadDetention" and teamed up with Captain America until I realized that the original golden age Human Torch, John Hammond, fought alongside Cap against the Red Skull, the boss of that particular level!
Lego Marvel Super Heroes features a cameo of Stan Lee as a prisoner in the Raft. You'd think that the creator of various superheroes like Spider-Man being in a high-security supervillain prison was just Rule of Funny... until you remember that he also created a Rogues Gallery for all of those heroes. He's in jail for creating all those supervillains!
Now at first you would think the Red Skull being a part of all this is No Swastikas / Disneyfication in action. But remember, neither Doom or Magneto or anyone else ever interact with or even acknowledge Red Skull's involvement. Except for Loki, who probably doesn't care enough to look into Earth's history and thus doesn't know to much about Skull's past.
This is possibly the first version of Galactus's coming to Earth that actually explains why he came down in New York, of all places.
This troper was confused by Deadpool's comment "Kingpin is offering low-price dental checkups! I HAVE NO TEETH!" Until realizing that he was referring to the fact that he was a LEGO, and LEG Os don't have teeth.
In Lego Batman one of the Joker's unlockable outfits is a tropical tourist's garb, with a purple fedora, Hawaiian shirt and a camera. It's a funky little ensemble, until you realize that it was what he was wearing when he shot and crippled Barbara Gordon.
...And yet Barbara is playable as Batgirl. In BOTH games. So it's really more Mythology Gag than anything else.
In Harry Potter a collectible type is "students in peril". No one seems to care about them no one notices them. Some just need to get something down or have a missing object, but what about the ones that are caught in devils snare or locked in the cupboard when the dragons destroying the towers?
Even when you know a student is trapped, you are powerless to help them until you get the right ability. In story, this can be years later.
On Weathertop, the Witch-king puts out a bonfire with a fire extinguisher. Pretty funny, until you realize that according to Word of God, Ringwraiths are scared of fire and water...and their LEGO counterparts don't seem to be overly afraid of either.
The fight with The Vulture has you tricking him into hurting himself by flying through promotional materials for Marvel heroes. When you remember Vulture's an old man, it feels more like you're taking advantage of his senility.
In LEGO Batman 2, Bizarro is a DLC character. He has the exact same abilities as Superman in the game. The problem is that his breath and Eye Beams are the opposite of Superman's. Superman has heat vision and freeze breath. Bizarro is supposed to have arctic vision and fire breath.
That is original Bizarro, who was just an imperfect clone of Superman, with all his powers and none of his smarts. It's not current day Bizarro, who is the literal opposite of Superman.
In the movie version, I doubt Wonder Woman needed to be in her invisible jet for all those scenes. Holding up Wayne Tower, for one, she probably didn't need it for.
Because invisible jets are inherently funny.
The subtitles spell M.O.D.O.K. with a K, yet he claims he's designed only for conquest.
Slave Leia and Carnage are in these games. What moral guardians?
This has been done before ('K for konquest') in other Marvel adaptations. In all probability, it's because they don't want to have a character shout 'I am designed only for killing!' in an age 7+ game.
