Nightmare Archeops is Archeops's Nightmare form, from the Nightmare World: darker, with 20% more health and move damage than a normal Archeops, and able to grow all the way to level 999.
Awakening a Archeops
Raise a Archeops to 5★ and level 100, then Awaken it from its details window with 10 Nightmare Shards and 100,000 gold. It becomes Nightmare Archeops (rank ☾1, level cap 200), and its Nightmare ranks take it up to 999.
Where it appears
It defends these Nightmare World maps (open from trainer level 100). A won battle there drops a Nightmare Pokémon 1 in 500 times, already Awakened, up to level 200:
| Map | Region | Level |
|---|---|---|
| Nightmare Route 213 Shore | Nightmare Abyss | 559 |
| Nightmare Connecting Cave | Nightmare Abyss | 699 |
| Nightmare Wela Volcano Park (Kiawe) | Nightmare Abyss | 777 |
| Nightmare Giant's Cap | Nightmare Inferno | 879 |
What changes
- It keeps its genes, moves, traits and held item; holding its Mega Stone, it becomes a Nightmare Mega.
- It wears no costume.
- In the Arena it fights at level 100 at most, with a normal form's stats.
- A shiny can't become a Nightmare form: it Ascends instead.
