- 12 custom bitcoin-themed choreographies (8 regular + 4 exclusive ultimates)
- Omni-morph system: creator morphs into any of 80+ archetypes instead of cycling 3
- 6% per-round cameo in non-creator fights — drops golden ₿ gifts to fighters
- Custom golden code rain entrance with persistent orbiting particles
- pickChoreography: 50% ultimate chance (100% on crits), all tier ultimates + 4 exclusive
- Server auto-assigns the_creator archetype on login/register for creator pubkey
