in the excellent miniseries, original sins, the young avengers have been battling the hood for control over all of the watcher's secrets. he tried to outsmart all of them, but prodigy was 10 steps ahead.
he used his advanced mental processing powers to create a mini cerebro out of a pasta strainer (cerebrat) and helped the hood gather every single on of the watcher's secrets onto every computer in the world. then the hood escaped, but not before prodigy encrypted the data with the most advanced and complex method known to man. and he did it all in his head, while he was distracting the hood with feigned incompetence!
