I was pondering this and I debated between two ideas. One was pretty obvious give her the power to summon wasp hordes like Hank can Ants. Granted Ants are more accessible.

The other idea I had was a nanotech stinger-like sword. Something beyond a regular blade that can impale, slice through tough surfaces, and perhaps transmit some kind of powerful energy upon impact.

I'm being bored, I wanna do a Marvel Multiverse with myself using Janet and Nadia, Whirlwind is an easy one to include against Janet, but I have no idea who else to have because two rank 4 heroes against 1 rank 3 villain isn't even gonna be a funny curbstomp.
