Valentina Venezetti

Valentina Venezetti is basically the brains behind stopping Kasey's plans throughout Phase 1. She's an inventor and engineer (hence the nickname) who works with her robot sidekick Velma to keep the world safe from interdimensional threats. Ngl, she's kinda the most competent person in the entire series.

Her portal-jumping abilities are rly the thing that sets her apart. She can create portals to jump between dimensions, which is honestly insane and makes her way more powerful than Pat could ever be. She uses these powers to track Kasey, gather intel, and try to prevent disasters before they happen. It's not always successful tbh, but she's clearly got a plan.

The tragic part is that Valentina and Kasey used to be best friends before everything went down. Kasey got obsessed with the pocketwatch and world conquest, and Valentina had to go against her. By the time Phase 1 hits, they're basically enemies, which is sad because you can tell Valentina still cares. She's trying to save the world AND stop her former bestie from destroying it.

Her partnership with Velma is also solid. The robot actually helps her do a lot of the heavy lifting when it comes to portal tech and dimension-hopping. Together they're way more effective than Valentina would be alone. She doesn't get enough credit for basically being the one keeping everything from falling apart.
