Portal, aka Melissa Doi, created a teleportation device that could open portals at any coordinates she chose. She accesses her device through an code sent via encrypted cell-phone commands. She had made her portals available to anyone willing to pay her high prices.

Standard scheduled portals cost $1 million minimum and typically include a 3-60 hour waiting list. Additional conditions such as hazardous cargo, discretion, illegal destinations, and/or immediate services each increase the price by 10.

For the most part, Portal provides mundane commercial teleportation services to corporations and governments. Sometimes, she'll provide her services to super-villains, terrorists, and anyone else able to pay her high fees.

Many governments would like to arrest Ms. Doi, but thus far she has been able to elude capture thanks to her ability to keep the location of her teleport device and staff a secret and the support of her corporate and underground contacts.
