I'd be interested in seeing what her Pokemon team looks like, assuming it's not just an Ampharos. Alternatively, since she likes music and radio, there could be something involving the Gold & Silver radio stations.
-Goldenrod Radio Tower plays Pokemon March and Pokemon Lullaby, which increase and decrease encounter rates, respectively. Perhaps Liz likes to listen to one of them? Trancing to Pokemon March and it 'attracts Pokemon' quality, or going into a nice relaxing trace with the lullaby.
-Team Rocket once broadcast a radio signal that screwed with the evolution of Pokemon at the Lake of Rage, causing the famous Red Gyarados. Liz might hear the broadcast and swap out her headband for a shiny colored version?
-That mysterious Unown signal that plays in the Ruins of Alph. I'm picturing Unown corruption, or just a general 'Liz submits to the will of the Unown' kind of thing, possibly with them spelling out O B E Y.
I understand that the Ampharos ears imply this, but Liz isn't a very Pokémon-focused OC. Far as we're concerned, she doesn't even exist in a world where Pokémon (consistently) exist. The ears are a novelty accessory that she wears because she's a big nerd with no fashion sense. In reality, the ears are a hold-over from when her design was inspired by another character who wears a novelty hairband. This doesn't mean we'll never do Pokémon-related stuff with her, but it's definitely not a central aspect of her character.
