The Reapers

In general:

Abnormal Ammo: The Reapers' new guns fire non-lethal bullets made from compressed psycho-reactive spray-paint.
Art Attacker: The Reapers' main way to fight, using spray paint to turn themselves into Half-Human Hybrid or by summoning music-themed monsters.

Empowered Badass Normal: With the rare exception of The Composer, Lady Freestyle and the Travelers who joined the Reapers, most of the gang is made of people who were empowered by the Composer.
Large Ham: Being a group of artists and performers of various backgrounds and horizons, the Reapers really know how to ham things up. Gangsta, Synth, Chiptune and the Composer especially stand out.

Meaningful Name: None of the names are given at random. The Composer is the leader of the Reapers and composes the Noises and Melodies, Southern is a former pig farmer from Texas, Grunge is a no-nonsense PRT officer, Gangsta is a black teenage rebel, Psychedelic has a few screws loose, Synth and Chiptune are DJs and Chicago comes from the place.

Rank Scales with Asskicking: The higher-ranking Reapers have stronger Power Tattoos.
Theme Naming: Every Reaper is named after music.

Our favorite Bug Girl, this time having triggered with the powers of The Composer from TWEWY. The founder and - reluctant - leader of the Reapers.

Asskicking Leads to Leadership: by virtue of being the most powerful Reaper thanks to Combo Platter Powers and the founder of the movement, she is the de-facto leader of the Reapers.
Benevolent Boss: As the Composer, she keeps claiming she's not the boss of the Reapers. They don't tend to listen and treat her as one regardless.

Combo Platter Powers: The Composer has this Up to Eleven, even by Worm standards. An incomplete list includes: Super-Strength, teleportation, Flight, pyrokinesis, projectiles, enhanced hearing, summoning the Noise and the ability to grant some of those powers to anyone via Power Tattoo. And of course, her Noelle Clone has all the same powers.
Deadpan Snarker: Has to deal with the mayhem a large group of free-thinking rebels can cause. And that's without the condescending behavior of the other gangs.
I Am Not Left-Handed: Holds back her abilities to the point that Dinah estimates that Coil has a barely over 5% chance of taking her down if she went all out.
The Leader: Type 4, Charismatic. She may not want to be the leader, but having founded the movement and being somewhat of a Magnetic Hero, people look up to her regardless.

Super-Empowering: The Composer gives Aisha/Gangsta a Cornix Canor tattoo on her back that lets her summon one at will. More generally, the Composer does this for all the Reapers to some extent.
Super-Senses: Has enhanced hearing.

Brian's little sister and a rising member of the Reapers, whose dedication quickly gets the Composer's attention.

Animal Motifs: Ravens. Her signature Noise is a Decadraven and the Composer later gives her a Cornix Canor for her loyalty.

BFG: While most Reapers get regular Tinker-made guns, he is handed a grenade launcher.
The Big Guy: The largest, most muscular member of the Reapers.
Friend on the Force: Is actually a PRT agent along with being a Reaper. He doesn't see a problem to belonging to both groups.

Buccaneer Broadcaster: They host the Reaper's Review, an illegal broadcast used by the Reapers as entertainment and to pass messages to the group.

Mundane Utility: Use their Canor bats to broadcast audio waves.
Shout-Out: Their introducing the Reaper Review sounds a lot like DJ Professor K from Jet Set Radio Future.

Playing with Fire: His teleporting creates a burst of fire.
Psycho Prototype: Averted. The Composer gave him a can of experimental Noise that messed with his brain, but he is very quiet and very loyal.

The Last Dance: His stated reason for joining the Reapers was that he was getting old and felt like joining a gang since it is the "in" thing to do these days.
Screw the Rules, I Have Connections!: Averted since he is secretly the uncle of Dodge, a Tinker specializing in pocket dimensions, giving him a powerful connection to the Tinker group Toybox, but the only time it's brought up is when he has his nephew send a case of guns to the reapers.
