Aqua

From Deltarune Wiki

Aqua is a recurring miniboss in Chapter 5. Her spinning knife attack was teased in the Chapter 5 announcement trailer[2] which alludes to the Cyan SOUL's attack in the Omega Flowey boss fight. Her speech text has a cyan tint to it. Her face sprite while talking is replaced by a cyan knife.

Profile

Appearance

Aqua is a light blue humanoid Flower given form by darkness (Not a darkner) with a dress, red shoes, long black hair that curls up to appear like devil horns, and a heart-shaped ribbon in her hair. She has one eye (Sometimes three), hidden by her bangs. She is shorter than the other flowers insinuating she prefers to represent herself as a child.

Personality

Aqua is playful, childish, and naive. She doesn't seem to understand what's going on most of the time. She is very violent, and consistently attacks the party and even other characters. She gets bored if doing the same thing over and over again, and usually decides to do something else afterwards. Her personality calls back to Jevil referencing a love for chaos, his laugh (UEE HEE HEE), and occasionally referencing Jevil's battle theme, THE WORLD REVOLVING. Her personality also resembles the Shadow Mantle holder in her playfulness being used in an often threatening or sinister way.

She is often seen accompanying Seth as they attempt to reign in her unpredictable actions. In return, Aqua is also seen encouraging Seth to play and seek enjoyment outside of Flowery's instructions.
