It really depends on the writer's focus. Some treat ki as a mana-like energy pool that fuels different magical effects, while others reflavor it as an inner magical talent that characters can channel into elemental spells or buffs. I was just reading a story that dealt with that kind of power-translation concept, 'The Transcendent Zombie System'. Its protagonist gets transported into a high-fantasy world and has to figure out how his unique undead-based abilities function under entirely new magical laws, which creates a similar kind of system-clash tension where the rules aren't directly compatible.
The most common trick is to make ki the 'internal' energy and magic the 'external' energy. Ki is drawn from your own life force, muscles, and spirit. Magic is drawn from the environment, gods, or ley lines. This lets characters combine them—using ki to shape and empower raw magical energy you've pulled from the air, resulting in attacks that have both incredible force and esoteric effects. Piccolo's Special Beam Cannon, but it's also a demon-banishing holy lance? Yes, please.
Lmao, just imagine Vegeta trying to explain ki sensing to a council of wizards. 'You fools, can you not feel the immense battle power approaching from the west?' And they're all just staring at crystal balls and chicken entrails. The comedy writes itself. The adaptation is less about the energy and more about the hilarious mismatch in methodology and arrogance.
I prefer crossovers where the systems are incompatible on a fundamental level. It creates more conflict. The mage's fireball isn't just hot; it's magical fire that burns the soul. Can a ki shield block that? Maybe not, forcing the Saiyan to dodge and find another way. It makes fights more tactical and less about who has the bigger number. That's a more interesting adaptation than just making everything the same.
Honestly, half the time I think writers just want an excuse to have Goku use a Kamehameha to deflect a dragon's breath or something equally awesome. The 'how' is secondary to the cool factor. And you know what? I'm okay with that. Not every fanfic needs to be a masterclass in systemic integration. Sometimes you just want to see two cool things smash together.

My favorite fics are the ones that cross with high-tier cosmic settings like 'Marvel' or 'DC,' because then the scaling actually works. You can throw Goku at a Herald of Galactus or Darkseid and it's a fair fight. The writers can focus on the spectacle and character without having to artificially weaken or strengthen anyone.
I've seen some pretty creative stuff in that tag. The magic in 'Black Clover' is so structured, with all its grimoires and elements, while something like 'My Hero Academia' is all about inherited quirks and personal body limits. A good writer doesn't just smash them together; they build rules for interaction. Like, can a grimoire adapt to analyze and copy a Quirk's genetic structure? Does anti-magic just nullify everything, or does it have a harder time against a power that's more biological than magical?
One memorable crossover with 'Jujutsu Kaisen' had Asta's anti-magic interacting with cursed energy like oil and water—it could dispel the technique but left the raw, negative emotion of the curse itself behind, which was a problem only Yuji could handle. That kind of thoughtful limitation creates conflict and forces characters to rely on each other's worlds' strengths. Makes the crossover feel like a real fusion, not just a costume change.
The real test for me is if the story still respects the losing system's logic. If everyone from another universe just gets a grimoire and calls it a day, it's lazy. But when you see a 'Naruto' character trying to mold chakra through a four-leaf clover book, and it behaving differently, that's the good stuff. It shows the writer actually cares about both worlds, not just using one as a fancy backdrop.
