As for Interference's attacks and abilities, here are a few:

Three-point Harmony: Anything that her sword/bat strikes three times she can destroy.  The rod vibrates when it strikes and she analyzes the vibrations.  Three vibrations give her enough information to pinpoint the resonant destructive frequency of the object being hit.  This lets her make a 'blunt slash', since the sword/bat has a cross-section that is an equilateral triangle, each of the three 'blade edges' is only 60 degrees, not particularly shape or good at cutting, but if its vibrating at the right frequency, it makes a horrible, jagged, shattering sort of cut through the material.  This ability doesn't work on some materials.  Interference has several materials memorized, like concert, and bone-through-flesh.

Active Denial System: Based on a real-life military technology, it is in essence a non-lethal heat ray in the form of a wall.  It causes intense pain but little to no damage in the top layer of skin and is used as a deterrent.

Beam snipe: Interference can fire high energy light beams from her body, channeled through specific outlets in her suit to snipe people down.  it is very lethal so she doesn't use it that much unless she's trying to cripple or disable a fleeing enemy.

Cymatic disruption field: Interference generates a large area of fluctuating sound pressure.  Depending on the frequency and intensity, it can cause mild nausea and vertigo, to actual physical trauma.  She can use it to cause earthquake-like effects and can cause significant collateral damage.  This ability relies on her placing her emitters to create an acoustic zone.  This ability may overlap with her study of magic by taking advantage of 'magic circles' and the magical properties of sound (chanting, reading spell aloud, etc.)

Solar Flare: A blinding flash of light (DBZ reference)

Mute: Interference can make herself inaudible by absorbing all the vibrations her body would otherwise generate.

Camouflage: self-explanatory.  Works like real-life camouflage, in other words, not perfect.  Much easier to trick electronic tracking equipment like radar, a lot harder to trick biological eyes.

Super vision and super hearing: comes with the sound and light abilities.

Her suit can let her punch through wood. It can also protect her from getting hurt if being hit by a fast-moving car, but getting hit by a truck will still be pretty painful and risky.  The suit also gives her the ability to control and command electronics that she has made (drones, robots, etc.) Technically, she's a glass cannon.  Her abilities can all be slightly modified depending on what frequency she's using, and she's always experimenting and coming up with new ways to use her powers.  When she figures it out, she'll start to incorporate magic into her technology, like runes of protection in her armor etc.

I'm hoping for more Assassin characters or NPC's for Interference to interact with, take orders from, or attempt to manipulate.  Depending on where the story goes, Interference may try to 'double-dip' and secretly join Zeta Squad.  Heck, she might even try to triple-dip and join Omega League too.  She would see no moral dilemma in doing so since every step is but a means to her goal.

I can foresee her having a power rivalry with Doc Williams.  While her use of light is more 'scientifically' oriented and thus restricted, Doc Williams' use of light is more esoteric and all encompassing, I feel.
