Is G.O.A.T a rarity in Coach a Fighter?
Unconfirmed. A G.O.A.T Challenge exists in the game world, but the Fighter Index shows only Reals, Legends and Shiny as tabs — so G.O.A.T may be a boss bracket rather than a card rarity.

A G.O.A.T Challenge exists in the world. Here is what can and cannot be said about it.
Updated
G.O.A.T is real — the sign is in the game
A G.O.A.T Challenge sign stands next to the fight area in the game world. That much is directly visible, and it is the only part of the boss system we can currently vouch for.
It also raises the question the rest of this page cannot yet answer: is G.O.A.T a fourth rarity above Legend, or just the name of the hardest boss bracket? The Fighter Index has no G.O.A.T tab, which leans toward the second reading — but that is an inference, not a finding.
What is reported but not yet confirmed
Gameplay commentary describes a boss system with Real, Legend and G.O.A.T tiers, a 24-hour cooldown per fighter against each boss, and rewards including Legend Rerolls and a chance to spin for the boss card itself — including its Shiny version.
One creator names Muhammad Ali as a boss opponent with unusually high stats. We list all of this as reported rather than confirmed, because it comes from transcripts of low-view videos rather than from a frame we have read ourselves.
Why the cooldown matters more than the rewards
If the per-fighter daily cooldown is real, it changes roster strategy: a deep bench is not just for league averages, it is a way to run the same boss multiple times per day with different cards.
That would make bench depth the primary boss-farming lever, which is worth testing before anyone spends Legend Rerolls chasing a single carry.

How often can you fight a boss?
Reported as once per 24 hours per fighter, meaning a deeper roster lets you run the same boss more often. We have not confirmed this on screen.
