Dragon Ball crossover idea: Subaru is from Dragon Ball Earth and when out on a snack run, happened to be kidnapped and turned into a Biotechnological type Android. He was modified in order to be a test of the Infinite Energy System, further testing on how to directly increase one's power artificially, and Ki Techniques experimentation. These tests were all a complete success, but he is nowhere near where Dr.Gero wanted in terms of the strength of his Androids, despite this being very high in Re:Zero terms, so he was planning on scrapping Subaru, but Subaru was summoned to Re:Zero directly from his pod. Because he was never intended to go into the field, he was never fully brainwashed, just had his memories extremely suppressed and temporary commands inputted into his mind when awakened for testing, no awakening sequence when he was summoned. When summoned, all that he can consciously remember is that he wasn't in this location before and his name is #12, but he instinctively uses his regular phrases, despite not knowing where they come from or why he uses them, is wearing some outfit with Red Ribbon paraphernalia(probably a tracksuit with their logo on it), and just wanders the capital until he walks into plot. Eventually Arc 4 is his memories getting fully unlocked, including pre-kidnapping ones and all the testing/modification/random spy footage of the Z Fighters that he saw(though some nightmares about some of this before Arc 4). For Subaru's pre-modification past, it's relatively close to how it is in canon, but slightly intensified because of how rare last names are in Dragon Ball(more in the shadow of his dad) and it also has the Dragon Ball plot happening in the background.
As an android, he can't cause instinctual fear, or even be instinctually detected, has access to all the standard Ki abilities and some nonstandard ones, is extremely strong, has the Infinite Energy System, and slow aging. I am unsure how to add the infinite energy system and ki to mana, the option that leaves him even more overpowered would to just say they are the same thing and Subaru has a Yin and Dragon Ball gate(flow method similar to reinforce if body with ki), other option is to have it so anyone can use Dragon Ball Ki moves if they train and Ki/Mana are completely separate(Dragon Ball Magic is completely separate from Ki, but they can be used for some of the same techniques))(with this, could say that Leaper is a Ki-based technique, like an ultra-short ranges Instant Transmission that activates faster). Subaru still has the ability to grow stronger by training.
I'd expect him to be genuinely confused in the thugs and Elsa encounters, just asking questions while being completely immune or extremely resistant to their attacks, accidentally shooting a basic Ki Blast on instinct when Elsa tries to attack Emilia. I'd expect him to take an extremely long time to learn about RBD, potentially learning about it against Petelgeuse if he blows himself up or when against characters with extreme hax such as Regulus. Also, Bomb that wouldn't come up until memories unlocked, could activate one in Gluttony if they get him and shapeshift into him(if they are able to get his real name, originally going by #12 until at least Arc 4). If he dies with Garlfiel, Unthinkable Present of Subaru being a subject to the mentor death curse and Garlfiel going further into being a Shonen Protagonist then before.
