Ah, Batman Beyond... They could have like the villain with the super sound powers (Shriek I believe his name was), or the guy who became that radioactive green skeleton. Mr. Freeze could be nice too, and would be DC's answer to Subzero.

Not to say they should be top priorities for a roster out of everyone else, but yeah.
