Man, okay, in these 'Chosen One' fics, Obi-Wan’s whole thing gets warped to fit the new narrative. He’s not just a master anymore; he’s the anchor point. Writers often give him this weird, passive 'seer' power where he has these constant, debilitating visions of the future—specifically about Anakin’s fall or potential redemption paths. It's less about active foresight and more about a curse he has to bear, which ends up driving a ton of the angst in the plot.
Then there's the bonding power. It gets amped up to eleven, way beyond the normal training bond. I’ve seen fics where it becomes almost a soul-tether, letting him feel Anakin’s pain or darkness across the galaxy, or even passively siphon off some of Anakin’s chaotic Force energy to stabilize him. It makes Obi-Wan a living regulator for the Chosen One’s power, which is a fun, tragic twist on his role as a teacher. He becomes less of an instructor and more of a failed control mechanism.
Finally, they lean hard into his Soresu mastery, but frame it as the ultimate defensive philosophy against a Chosen One gone wrong. The fics where he has to fight a fallen Anakin always highlight that—not just blocking blasters, but containing a hurricane of Dark Side power. It’s portrayed as the only thing that could possibly hold the line, a stubborn, unyielding wall of light. Makes for some heartbreaking final duels where his greatest power is just enduring.
