Alphys

The Foil version of Alphys.

About
A well-kept, dark secret are usually the toughest to come to terms with, and Alphys is no exception. Given the nature of the Foil and all the history behind it, this reclusive Foil is rarely seen.

Foil's Representation
Fear of rejection, and of what will happen to her if the other Monsters found out about the Amalgamations.

Personality
Highly anti-social. Skittish and quick to flee, foil!Alphys is hard to converse with. She's fearful and suspicious of everyone so good luck talking to her, let alone finding her.

Appearance
Pale complexion, perpetually tired and perhaps a little malnourished. Has a slight tremble and is constantly fidgeting anxiously. Lab coat has inky-black splotches here and there, matching the faded black smears on her hands and tail.

Abilities
You'll have to go through a couple lines of defense before you're able to attack her directly. First, she uses a remote control to attack with "Minitons" and bombs, an attack much like Mettaton uses in the actual Undertale game. Next she'll be protected by the Amalgamations which you'll have to defeat, one-by-one in order. Lastly, you'll finally be able to attack her directly; during this phase, she'll hurl filled lab vials at her opponent in a panicked frenzy, each color liquid having a different effect and lasting one turn:

Yellow - Attacks foil!Alphys' opponent

Red - Heals foil!Alphys' opponent

Purple - Poisons foil!Alphys' opponent

Orange - Lowers foil!Alphys' opponents' offense

Blue - Lowers foil!Alphys' opponent's defense

Green - Heals foil!Alphys herself
