What is a Shiny fighter in Coach a Fighter?
A distinct collection category tracked by the Fighter Index under its own cyan tab. Players report Shiny cards start with boosted stats, though we have not confirmed the size of that boost on screen.
Collection
A whole collection axis that the rest of the web has not written about at all.
Updated
The Fighter Index has four filter tabs: All, Reals, Legends and Shiny. Shiny is cyan, sitting alongside the orange Reals and red Legends tabs.
That placement is the strongest evidence available: the game treats Shiny as its own collection axis, worth its own filter, not as a cosmetic footnote.

Gameplay commentary describes Shiny fighters as starting with boosted stats rather than merely looking different — a shiny pull is reported as arriving at a materially higher Overall than the same card would normally.
We can confirm the tab exists and is cyan. We cannot yet confirm the stat boost, whether Shiny is a rarity of its own or a variant that can land on any card, or how a Shiny is obtained. Those stay on the open-questions list.
Because a short honest page about a real mechanic beats a long confident page about an invented one. Search for Shiny fighters in this game today and you will find nothing written at all — the topic exists only in low-view gameplay videos.
When the Shiny card treatment and its stat effect are captured on screen, this page gets the numbers. Until then it gets the truth.

Not confirmed. Shinies have been reported from ordinary reroll pulls, which suggests they are a low-probability outcome rather than a separate acquisition path.
