Fang and dog Sirius reappear soon after they die in gameplay, like everyone else in the game. Werewolf Lupin breaks apart like the other humanoid characters but he also revives.
Only if you name one of your custom characters one. However, as a Harry Potter game it’s tied to one of the most transphobic creators of our time so keep that in mind before buying it.
Harry and Ron use magic to disguise themselves as girls and there's a cutscene where a man uses Polyjuice Potion to resemble a woman but neither are directly played for comedy. Only the part where Dobby blasts Lucius Malfoy with magic and gives him pink underwear is played as a joke since Harry and Dobby directly laugh at him, Years 5-7 also has one of these jokes with Luna Lovegood's dad dressing like her.
The heroes commit some questionable acts, notably dropping a prefect into a trapdoor that probably contains a monster that eats them (indicated by a burp). None of them are police (Harry becomes an Auror at the end but the games never allude to this) so this doesn't count.
Every playable character in the game is a LEGO Minifigure who gets broken apart when they die. This doesn’t count since the LEGO pieces themselves are undamaged and the figures don’t belong to a kid.
Harry is just forced to do housework and locked in his room, as far as abuse goes. In gameplay, you can harm and kill any Hogwarts student you find, including using the Cruciatus (torture) curse on them.
You have to kill gigantic LEGO bees and spiders in the console version, leeches and moths that aren’t made of LEGO pieces must be killed to make potions in the DS/mobile version.
Aragog’s carcass is in Years 5-7 but aside from animals you kill and LEGO meat there are no dead animals. The smashed, bleeding bugs in the DS version also count.
Cruikshanks is the only playable cat and he falls over if you zap him but he gets back up (unless you do this too close to Hermione, in which case he disappears into smoke). You can always resummon Cruikshanks if this happens, though.
The gigantic bees are the most triggering despite being made of LEGO pieces but the DS version also has non-LEGO moths, leeches, and maybe a few others.
They make a big joke of how much a character eats and then given a pig tail. There is also a character that is canonically plus sized/larger/fat and i think they try to represent that with a lego figurine
You have to hit spiders with a car in the Forbidden forest. You can run over people with all moveable objects. Nothing bloody. It can actually be funny, they just get right back up.
The DS and mobile versions have creature blood in the potion mini-games. The console versions have nothing resembling gore, outside of dismembered Minifigs.
