How Demon Hound compares
Neighbors by income in Angels & Demons (7 of 18):
Other Cosmic pets
Demon Hound guide
Demon Hound earns $25M/s, the same income as the T-Rex from Prehistoric. The difference is that the T-Rex is a Secret behind a 2h 30m egg, while the Demon Hound is a Cosmic-rarity pet in Angels & Demons, where that number counts as mid-table.
Egg and reward
- Biome: Angels & Demons, 12th in the biome order
- Speed requirement: 20B
- Zone guardians: ArchAngel, World Burner and Aetheron
- Hatch reward: +20m Speed and $2.5b
- Base weight: 9,000 kg
The wiki does not yet record the egg's grow time.
The +20m Speed reward is a big jump from the zone's lower eggs: five times the Mythics' +4m and two and a half times the Sacred Moth's +8m. The $2.5b in cash would cover the Red Trail (750M, 4×) more than three times.
Where it sits
- 11th of 18 in Angels & Demons, counting from the highest earner (tied with the Holy Peacock)
- 3rd of 28 Cosmic-rarity pets (tied with the Holy Peacock and Spiderpig)
- 80 of the 198 pets earn more overall
It is the stronger Cosmic tier of the zone, alongside its stat twin the Holy Peacock, which has identical income, reward and base weight. Above them, the Secret tier starts with the Gargoyle and Pure Jellyfish at $225M/s, nine times more.
Since the zone changes every night between an Angel theme and a Demon theme, each with its own 8 pets, the Demon Hound and Holy Peacock may not be in the nests at the same time; either one gives the same result.
Mutation and weight estimates
Using the formula the wiki documents (its calculator is labelled beta):

- 100× base weight: about $428M/s
- 200× base weight: about $592M/s
- Rainbow with 100× weight: about $1.5B/s
