Spark (Mario + Rabbids Sparks of Hope)

Sparks (originally dubbed Rabbid Lumas by Beep-0 before the heroes decided on their final name) are a hybrid species of Lumas and Rabbids that appear in Mario + Rabbids Sparks of Hope. They resemble Lumas, but with a Rabbid's face and ears. They come in a variety of colors and designs, with some being larger than others, and each has their own powers. During the game's story, Cursa sends her army to capture the Sparks in order to absorb their energy, among which a special group of minions called the Spark Hunters, and Mario and his team set out to rescue them.

Prior to the events of the game, Sparks were created as fusions between Lumas and Rabbids caused by an energy blast at the Comet Observatory as Rosalina was fending off Cursa.

Gameplay
Sparks are used to assist the Heroes, whether in battle or by helping the player navigate through the environments in the game. They are recruited by clearing battles during the game's story plot within Main Quests, and some can also be recruited after clearing special sidequests called "Spark Quests".

Sparks used in battle
Each Spark that is used in battle has two abilities that is bestowed on the Hero that equips it: an active ability called a Power that a Hero can use in battle as a menu selection, and a passive ability called a Bonus. Powers are unique to each Spark and can be used to either augment the Heroes' weapons and abilities, healing the Heroes, attacking enemies, and other abilities. Bonuses can enhance the Hero's attack power, increase defenses from damage taken, and other abilities. Some Bonuses are shared by other Sparks. The player can improve both of a Spark's abilities at once by raising its levels with Star Bits from the Sparks menu.

Initially, each Hero can only use one Spark, but can be allowed to use two after clearing the Cold Mouth of the Mountain Quest in the game's second world Pristine Peaks.

Each Spark joins the party at LVL 1, and has a maximum LVL of 5. Initially, the player can only raise their levels to 2: only after the Heroes' LVL reaches a certain number can the player unlock the next: LVL 9 for LVL 3; LVL 15 for LVL 4; and LVL 21 for LVL 5. In The Tower of Doooom DLC, the Hero LVL requirements for reach LVLs 3-5 are LVLs 4, 7, and 10. In The Last Spark Hunter DLC, all Sparks available for the player are at LVL 4, including those that join the party, and can be upgraded to LVL 5 at any time.

All Sparks require the same amount of XP upon level up. Each button press with to feed Star Bits to a Spark uses 10 Star Bits for 10 XP. Using a Star Potion for a Spark automatically raises its LVL.

Sparks can also be enhanced by unlocking the Spark branch of a Hero's Skill Tree with Gold Prisms, obtainable by defeating Giant boss enemies. In The Last Spark Hunter DLC, the Spark branch in already unlocked for every Hero's Skill Tree.

Beep-0 Power Sparks
Some Sparks do not assist in battle, but instead bestow Beep-0 powers that allow the player to discover hidden areas and items on the field. As they are not used in battle, they cannot be enhanced from the Sparks menu.

List of Sparks
Up to thirty different Sparks can be recruited in the game, although Decibel, Twinkle, and Drizzle are not counted. Recruiting Sparks counts towards 100% completion on a save file.

The Sparks Berserk, Vampgeddon, Electroquake, Cryodash, and Mayhem appear in The Last Spark Hunter DLC.

Memory bio
''After an exhaustive analysis of our brave Spark allies, I can confirm that they are what they appear to be - a fusion of Luma and Rabbid. The Sparks' memories as to how exactly this came to be are lost to them, yet two instincts remain - their affection to their "mama" - Rosalina - and their deep fear of Cursa, who pursues them relentlessly throughout the galaxy in hopes of seizing their tremendous power for itself.''
