- Nuclear Mantis, top of the Laboratory's Biohazard Egg: $1.5B/s.
- Equinox, Angels & Demons: $1.8B/s.
- Dreadstinger, Experimental Egg: $2B/s.

What is known about it
The wiki lists Archdemon Dragon as an event pet and gives it a base weight of 120,000 kg, one of the heaviest values it records. It does not name the event, the date or the method of distribution. The name suggests the Demons side of the Angels & Demons biome added in Update 4, but the wiki's list of that update's Darkness animals does not include it, so there is no confirmed link. The general rule the wiki gives for limited eggs is that event eggs never spawn in biome nests and come from the Store or from special events such as Admin Abuse.
It ranks 4th of the 17 event pets and 26th of 198 overall.
Estimates
Using the formula the wiki documents:
- Golden: about $3.12B/s
- Rainbow: about $4.38B/s
- 10× base weight: about $5.17B/s
- 100× base weight: about $21.4B/s
- 200× base weight: about $29.6B/s
- Rainbow at 100× weight: about $74.9B/s
A Golden copy would already pass Nightflame and Cthulhu at base ($3B/s each).
