Herald of Galactus
- Silver Surfer: Once per fight, if Silver Surfer were to lose more than 25% of his life in a single hit he instead consumes the Power Cosmic Buff and gains an Indestructible Buff for 6.0 seconds.

Every sig anchor × rank at A0. Sig levels in between interpolate smoothly (PCHIP) and round to the nearest 10 BHR — matching the in-game display.
| Sig | R3 | R4 | R5 |
|---|---|---|---|
| 0 | 20,460 | 24,990 | 29,630 |
| 20 | 22,570 | 27,580 | 32,680 |
| 40 | 23,430 | 28,620 | 33,920 |
| 60 | 24,140 | 29,500 | 34,960 |
| 80 | 24,790 | 30,280 | 35,890 |
| 100 | 25,370 | 30,990 | 36,730 |

BHR at each signature level by rank (non-ascendable — A0 only). The curve is concave — sig 0 → 100 captures roughly two-thirds of the gain from sig 0 → 200.
