Some Re:Zero fanfic ideas, crossover mostly

miscellaneous crack ideas 5

Crack 1: Subaru has the ability to Suplex anything regardless of size(self included), but this doesn't do much but disorientate higher level opponents.(can have it so without a target, he just suplexes himself, suplex the Whale? Technique taught by parents?)

Crack 2: Subaru has the ability to place down Standees, they work like they do in Mario Wonder, including allowing the dead to revive shortly after death(self included) and they look like him doing random poses.(unsure if the corpses would be erased)

Crack 4: Throne room scene, but it turns into a Ace Attorney trial somehow.

Crack 5: Have Subaru have Air Shoes(Like ones Shadow wears in Sonic), which are a normal consumer product on the world that he is from and he is quite skilled with them(they run off of the mana in the air and are designed for the trace amounts of mana that exist on Earth, so Subaru has to get used to their much higher output in the world of Re:Zero. They are controlled by magic subconsciously or something and because of this, his gate is marginally better than in cannon?). He could also know exactly how all the components are put together.

Crack 7: Mirror universe situation where all the morality and personalities are flipped.

Crack 8: Subaru spawns in on the first day and his antics get all the royal candidates and several knights to start stalking him from a distance all independently, normal stuff for regularly involved characters until a reason for them to make themselves known happens.

Crack 9: The one who wins the royal selection is the one who gets the least amount of votes and this is only known to the candidates.

Crack 10: Anyone who died after the most recent checkpoint and before Subaru dies remembers the loop that they died in.(Once found out about, it leads to Subaru doubting that he is the one causing RBD until he notices that others that die don't have the Witch scent increase that he does.)(They remember only the loop(s) they died in, even if it's not the most recent loop)

Crack 11: Upon RBD activation, Subaru and whoever he is closest to distance-wise at the end of the loop swap their start of the loop positions.

Crack 12: Subaru is wearing a shirt with his own face on it upon transport.

Crack 13: Any transformation does a Yoshi's island transformation sequence(jingle included).

Crack 1: Biyon Mario Wonder Effect constantly happening in some radius around Subaru, including himself(wonder effect is that by default, everyone stretches so they're very tall and can crouch down to regular height, light is somehow lowered to the point that everything is silhouetted). The insanity of Subaru spawning leads to random people just breaking through their roofs and characters such as Elsa trying to fight while everyone is tall.(Could just be a normal thing for people near where Subaru is from and have it apply to other Isekai characters). An alternative to the radius setup is for it to just be the default in the Re:Zero world or just Lugunica and Subaru suddenly has to deal with it upon summoning(architecture would probably be set up so it's much harder to have random people just break through the ceiling).

Crack 2: Instead of a book of wisdom, Roswaal has a strategy guide with similar properties(can also have the witch cult also having that instead of those gospels).

Crack 3: Leaper technique is taught in the early grades of school in the version of Earth where Subaru is from as a transport technique, so he(and Al) knows how to do it. It has been scientifically investigated and it is public knowledge how it works in that world, many ways to completely abuse how it works have been found, but viewed primarily as a transportation ability. Much infrastructure and security on Earth is adapted to most just having the ability to do successive short-range teleportation. Very confused when he finds out how people view it in the Re:Zero world.(perhaps his world calls it something differently, like simply "short-range teleportation technique")(when told that the ability breaks the rules, he could explain how it follows the rules in exhaustive detail). Him off-handily mentioning something like the widespreadness of this causing a ton more alarms being put inside buildings, but them always missing some area could prompt Felt to ask him to teach it to her. Some knock-on effects of this technique being widespread that he could talk about is that versions of sports that allow this and battlefields have become much more chaotic.
