The Daleks were mutants genetically engineered by the Kaled scientist Davros.  Their goal was to exterminate all other life forms, and waged a strategic war across the universe. They were frequently encountered, and defeated, by the Time Lord known as the Doctor.
While usually inhabitants of the 5556 Continuum, exclusively, a Dalek turned up in the Baxter Building of Realy-8910 as part of an immense waiting line of beings wishing to speak to Reed Richards. While in line, it evidently accosted Kitty Pryde and Alistaire Stuart; Kitty threatened to "exterminate" it if the Dalek tried anything, while Stuart insisted they hadn't met before. It is unknown if this was a dimensionally misplaced Dalek, or another creation of the Impossible Man like most of that Earth's inhabitants.

- Alistair Stuart was an homage to Doctor Who, hence the Dalek's ill-willed interest in him.
