Despite her looks, personality, and behavior, Lor is incredibly powerful, even outside of her combat mode. She simply chooses not to do much with her capabilities, mostly because she has no reason to, and usually the sheer strength she has just manifests as doing favors for the community. Like using one of her oars to move a large tree off of a road with the same ease a child would use to scoot around a toy car. Very nice for strangers, probably at least somewhat terrifying to everyone who knows that she simply chooses not to be evil. Kindness is a choice she makes every day.
With that in mind, if someone were to threaten her friends or family(aka Magolor and the group of friends she has collected that call her mom), she would be a force to be reckoned with, even without switching modes. If you ever see purple Lor, it’s best to keep your distance for a while, because chances are things are going to get messy. She only enters combat mode in emergency situations, if nothing else has worked and violence seems to be the only/best solution. An important thing to note: she fights differently than she did in Return to Dreamland, on account of not basically being on autopilot. She can make strategic decisions, and if that means just spamming a few attacks instead of using every single one, she will.
On that note, she’s a really good fighter, even if she doesn’t like doing so. Starcutters(and Umbramakers) all have elements, kinda like the ones you can put on weapons in Star Allies. Lor has the wind element, based on how she moves and her attacks. Just look at how her oars can be aimed before targeting the opponent and how quickly they move, how her wings seem to ignore physics to stay in the air and fly in place, how quickly she can just charge forward even when starting from being stationary, and the vortex she can shoot with her sail being a literal tornado that she can direct. All of those make the most sense if you consider manipulation/creation of air currents. Her star projectiles are just condensed magic, though, and the colored spheres she can fire off(and the big one she makes around herself to ram into the opponent) are all aether magic based.
She fights best when she’s alongside others, though, taking on a mixed attack and defense role, the first being because of her sheer firepower and the second due to her durability and ability to make a near-impenetrable aether shield around herself if needed. Being a computer also means she can calculate what to do extremely quickly and effectively, so no worries about her bumping into any allies or risking friendly fire. Really, her only drawbacks are not being able to fight in enclosed spaces, underwater, or in areas where, even if she can stay in the sky, targets have a lot of stuff to hide behind or under. She would also be outclassed by modern Starcutters, but that isn’t really relevant because they’re all in Halcandra and Lor avoids that place like the plague.
