Picard: he never exceeded or failed but he was in a loop a few times (“Time Squared”, “Cause and Effect”, “All Good Things…”)
Sisko: he was always behind and sometimes stuck in the future (“Past Tense Part I and II”, “Trials and Tribble-ations”, “Children of Time”)
Janeway: she was always behind and ahead of her time and some times speeding ahead (“Future’s End Part I and Part II”, “Timeless”, “Blink of an Eye”, “Relativity”, “Endgame”)
Okay, what I meant was, Geordi did use one.
But yeah, this is clearly Sisko but I don’t recall him shaving his head in any scenes.
