Not quite as fast as, say, the Asgardians, as Delia's using a motorcycle to make up for the differences in raw capability (she is, after all, your standard humanoid meatbag who's unique abilities aren't useful here, as you might expect), Delia's presence is first given away by the bike engine sound getting closer, then, with a swing, she pulls the bike into a sideways slide to try and stop.

Snow and ice make this a difficult prospect at best, all things considered, and she'll probably want a new pair of winter boots when this is over given she has to kick one leg out to maintain her balance.

But as soon as she's stopped, she slings the rifle off of her shoulder, takes aim at one of those zippy little robots (which, in her humble opinion, kind of vaguely resemble a couple of those drones her engineer's built before), and fires. A wide, circular green burst of energy bursts forth from the end of her rifle.

Disruptors cause damage to the target by breaking the bonds of atoms, and this burst in particular is big enough to pass over most targets bodies like a pulsating wave, dissipating momentarily afterwards.
