Digimon Story Lost Evolution
Mermaimon is #199, and is an Ultimate-level, Balance-class, Aquan-species Digimon with a resistance to the Water element and a weakness to the Thunder element. It possesses the Confusion Guard, Item Hunter, and Digimon Professor traits, and has the special skill Dive.

It dwells in the Angler Tunnel. When defeated, it can drop the debug plate for Mermaimon or the Spirit of Water.

Mermaimon digivolves from Hookmon and can digivolve into MarineAngemon or AncientMermaimon. In order to digivolve or degenerate into Mermaimon, your Digimon must be at least level 28 with 115 attack and 90 speed, but only once you have revived Mermaimon.

It can be hatched from the Water DigiEgg.
