Marion Van Arkel is a character from Crosscut. She comes from a family who used to own a uranium mine somewhere in Southern Africa.

Marion had opened up the mine to take as much uranium as she could retrieve to sell to an anonymous buyer, but was discovered by Scott Tracy who had originally checked out the mine with the intention of sealing it shut. After overloading the main lift - causing it to break and become unusable - she helps Scott locate a rear exit to the mine for them to escape before they suffer radiation poisoning.

Disappointed that she could not sell any of the uranium and thrown into financial ruin, Scott recommends her to Colonel Casey of the Global Defence Force who thinks she has a use for Marion's expertise.

Marion was voiced by Teresa Gallagher.
