Alvida's fruit makes a case study out of vanity as literal super-power: she was introduced in Chapter 1 as a self-declared "ugliest woman in the world" pirate captain, and returns in Vol. 11 having eaten a Devil Fruit that happens to grant flawless skin — a power that reads, on the page, less like a battle ability and more like Alvida getting exactly what she always wanted from the universe. The reveal scene leans into that: her own lines linger on cosmetics before combat, boasting that her skin "cannot be marred by any attack" a full panel before she ever mentions using the power offensively, and Coby's blunt-honest reaction (もういかなる攻撃も..."barely enhanced... your freckles are gone") plays the whole transformation as a beauty punchline stapled onto a Logia-adjacent defense.
On translation, Sube Sube is the cleanest entry in this dictionary. Every occurrence the corpus returns — four total, a small sample but a unanimous one — renders スベスベ as "Slip-Slip," with no SBS aside or glossary page pulling in a competing gloss the way Chop-Chop and Flower-Flower both get elsewhere. The attack name that follows the reveal, スベスベシュブール (a garbled OCR read of what's almost certainly スベスベシュプール, a pun on the French-derived ski-track loanword シュプール/schuss-spur), becomes "SLIP-SLIP TRACKS!" at Vol. 12, p.12 — VIZ carrying the reduplicated brand straight through into the move name without breaking stride, the same discipline Gum-Gum gets but that Buggy's fruit never quite achieves.
A later glossary-style SBS page (Vol. 30, p.108), listing over a dozen Devil Fruits back to back for a reader's benefit, confirms "Slip-Slip Fruit" holds even outside dedicated dialogue — it sits in a dense list alongside Gum-Gum, Chop-Chop, Bomb-Bomb, and others, unchanged from its Vol. 11 debut. For a fruit this narrow in stated combat use (Alvida barely appears again after her introduction arc in this corpus's range), that naming consistency is arguably the strongest evidence the corpus offers that VIZ's house style for Devil Fruits was locked in early and applied evenly, at least to the fruits that didn't generate a decade of new attack names to keep track of.
