Decibel

"HA, SORRY! IS IT OKAY IF I COME WITH YOU? I'M NOT MUCH GOOD IN A FIGHT BUT I CAN DO OTHER STUFF! I HAVE SONIC POWERS STRONG ENOUGH TO MOVE HEAVY OBJECTS - EVEN DESTROY THINGS SOMETIMES!"

- Decibel

Decibel is a Spark that appears in Mario + Rabbids Sparks of Hope, located in Pristine Peaks. Decibel is found in a tree not long after the heroes land in Pristine Peaks. Unlike other Sparks, Decibel does not fight in battle. Instead, Decibel flies into Beep-0, granting him the Wave Power, enabling Beep-0 to move certain blocks, rocks, and destroy weaker rocks.

Decibel is a glowing purple Spark that is highly excited, as indicated by its text boxes containing all capital letters. It even destroys a rock when the heroes free Decibel from the tree. It is named after a unit used to measure the intensity of a sound of an electrical signal, comparing it with a given level on a logarithmic scale.

Trivia

 * After the heroes free Decibel from the tree, Bowser can briefly be seen in the cutscene afterwards. This is an error.
