Adagio Dazzle

Adagio Dazzle is the main antagonist of Rainbow Rocks Story Arc and is leader of the Dazzlings.

Appearance
In Equestria, the sirens' appearance is a Hippocampus.

In the human world, the Dazzlings are shown to possess translucent fin-like wings in their anthro forms, unlike their true forms.

Their siren forms are summoned as astral projections from their pendants and used to weaken the Rainbooms.

Aside from flashbacks, Adagio's true form is never physically shown in the film, but she and her fellow band members gain pony-like ears, extended ponytails, and translucent wings.

They also summon astral projections of their true siren forms from their pendants.

Personality
Adagio Dazzle is shown to be scheming, manipulative, and only concerned with gaining power and being adored by others (not unlike Sunset Shimmer when she was evil, except while Sunset Shimmer had some morals, Adagio had none).

She is able to sway student opinion with ease and trick Trixie into removing The Rainbooms from the competition.

Adagio also bears considerable contempt toward her fellow sirens Aria and Sonata, calling them "idiots" and generally disliking their company.

She was also both arrogant and sadistic; when Sunset Shimmer confronted her Adagio deliberately emphasized the similarities between her and Sunset Shimmer's past self, while also implying that her friends don't really care for her and see her as a liability.

Her character is defined in one line: "it doesn't matter who you hurt if you're just proving you're the best", a line that also seems to suggest she is a narcissist.

She is arrogant and vain, not viewing her fellow sirens as equals, getting annoyed when Aria suggested she lead for once.

This is justified somewhat since she is incontestably the best planner among the Dazzlings.

However, she is so self-assured that she never considered getting defeated, thus this arrogance led to her downfall.

Powers, Skills & Abilities
She like the other Sirens can hypnotize people with her singing.

In Her astral form she can shoot red beams from her mouth which is how she nearly won the battle against the Rainbooms.

Using her dark magic, she is able to sway the students' opinion with ease and trick Trixie into removing the Rainbooms from the competition.
