Katie is highly intelligent; at five she was literate and able to write fluently enough to compose a "War Journal", copying the Punisher. She is later depicted as a genius who has skipped several grades of school and can program supercomputers. In the original series, Katie had a close, sibling-like relationship with the fifth Power Pack member, Franklin Richards.

She was able to fly quickly, leaving a stream of rainbow light in her wake. While Katie as Starstreak was never able to break the sound barrier as her sister Julie supposedly did, she did refine the
