What Powers Does Jaune Arc Gain In 'Jaune Arc SI In The Multiverse'?

In 'Jaune Arc SI in the Multiverse', Jaune's powers evolve in wild ways that make him stand out even among multiverse travelers. His baseline Aura gets a massive upgrade, letting him tank hits that would flatten normal Huntsmen. What really amps up his game is the ability to absorb skills from alternate versions of himself across dimensions. One minute he's channeling a Jaune who mastered Dust weaving, the next he's borrowing sword techniques from a version trained by legendary warriors. His Semblance morphs too—instead of just boosting others, it starts reflecting damage back at attackers or creating temporary clones. The deeper he dives into the multiverse, the more broken his powers become, culminating in reality-warping abilities that let him briefly alter local physics. The story does a great job showing how overwhelming this would actually feel, with Jaune struggling to control powers that keep expanding beyond his comprehension.

The power progression in 'Jaune Arc SI in the Multiverse' is some of the most creative I've seen in fanfiction. Jaune starts with his canon abilities but quickly diverges as he interacts with different realities. His Aura doesn't just grow stronger—it develops reactive properties, automatically countering attacks based on past experiences. This makes him nearly untouchable against foes who rely on predictable patterns.

What fascinates me is the skill theft mechanism. Every time he encounters another Jaune variant, he gains fragments of their memories and abilities. A stealth-focused Jaune gives him shadowstep techniques, while a scientist Jaune grants sudden engineering expertise. These aren't simple power copies either—he has to reconcile conflicting muscle memories, leading to hilarious and dangerous mix-ups during fights.

The Semblance evolution is where things get cosmic. Midway through the story, he learns to 'overclock' his allies' abilities by temporarily borrowing power from alternate versions of them. This leads to insane teamwork combos, like Ruby moving at time-dilation speeds or Nora summoning lightning storms. By the latest chapters, he's accessing dormant abilities from ancestral Jaunes, including a terrifying warform that merges aspects from dozens of timelines into one unstoppable fighter. The author balances these upgrades by showing the mental toll—Jaune sometimes loses chunks of time or suffers personality bleed from dominant alternate selves.

What makes Jaune's power set special in this fic is how chaotic it feels. Unlike typical progression fantasies where skills neatly stack, his abilities arrive in unpredictable bursts. One chapter he accidentally activates a variant's pyrokinesis during a bar fight, the next he's stuck with a berserker Jaune's bloodlust for hours. The multiverse isn't a buffet—it force-feeds him powers whether he's ready or not.

His Semblance becomes a revolving door of effects. Sometimes it amplifies teammates normally, other times it spawns temporary constructs based on alternate team compositions. There's a heartbreaking scene where he unknowingly summons a phantom version of Pyrrha from a timeline where she survived, only for her to dissolve mid-conversation. The story uses these powers to explore identity—when Jaune starts dreaming in fragmented realities, he can't tell which memories are originally his anymore.

The physical changes creep up too. His eyes occasionally flash with the colors of other Jaunes' Auras, his voice shifts accents mid-sentence, and scars appear overnight from battles he doesn't remember fighting. It's less about gaining superpowers and more about surviving the process. The fic excels at showing power growth as both a gift and existential crisis.
