Cursa the Destroyer

"What are we waiting for?! WE'RE HERE, ROSALINA! WE'RE HERE!"

- Rabbid Rosalina

Cursa the Destroyer is a Main Quest in Mario + Rabbids Sparks of Hope, located on Cursa's stronghold and is the last Main Quest in the game.

History
The heroes arrive at Cursa's stronghold, and use the Shield Buster from Momma to destroy the barrier. After it is destroyed, it reveals the Comet Observatory, with the core to the Darkmess Dimension in the center. Due to the large density of Darkmess energy around the Comet Observatory, the thrusters for the WM ARC cannot function, so the heroes land on debris from the barrier.

To reach the Comet Observatory, the heroes must get past two Darkmess Puddles, which have Darkmess clones of Bowser and Edge, known as Darkmess Bowser and Darkmess Edge, respectively. After defeating the latter, Edge reveals to the group that she was created by Cursa, and rebelled against her. The heroes then use a golden cannon to reach the Comet Observatory.

In the Darkmess Dimension, the heroes confront and defeat Cursa, as well as free Rosalina. Afterwards, the heroes travel back to Peach's Castle, and Rosalina thanks the heroes. She also reveals that the Sparks are alive and well. She then asks what Edge will do, along with offering Rabbid Rosalina to join her. Rabbid Rosalina likes the offer, but decides to also stay with the heroes, declaring that they are her family. Edge says that her "old friends" have have to find new professions, and decides to stay with the heroes. Rosalina then also thanks Bowser for his actions, who is not happy with what he has done. Rabbid Peach, Rabbid Mario, and Rabbid Luigi then play with Bowser, worrying Mario. He tries to stop the Rabbids, but Bowser breathes fire, launching them off.
