"Oh, how I do love proving my laws of motion."
—Isaac Newton to Martin Stein[src]

Sir Isaac Newton is one of history's most prominent physicists from England who was one of the scientists kidnapped by the time traveler Martin Stein to assist him in discovering a way to divide the Firestorm Matrix, so that the Firestorm powers would be left with Jefferson Jackson alone. Newton accidentally became an ally of the Legends, defeating a Grodd-controlled Sara Lance and enjoying Lady Bird Johnson's secret pie recipe alongside the rest of the team as they left 1967's Vietnam.


Isaac Newton, judging by his clothing, came from the same time period as King Louis XIII and Queen Anne of France. He was a resident of England who, at some point, was knighted by the Crown, receiving the honorific of "Sir". Eventually, Isaac became a well-known physicist, one of the most famous in history, which led to him being kidnapped by Martin Stein along with history's other prominent scientists, such as Galileo and Marie Curie. According to Stein, one of Isaac's discoveries happened due to him being hit with an apple.

Trapped on the Waverider in 1967, Isaac and the other kidnapped scientists were forced to work for hours by Stein, who desperately searched for a way to separate the Firestorm Matrix in a way that would allow Jefferson Jackson to keep his Firestorm powers. When asked for his opinion, Isaac complained that the kidnapped needed a reprieve after their tedious session. While Galileo and Marie Curie disappeared earlier, presumably sent back to their time periods, Isaac was left to wander the ship for at least one more day.

When Stein was attacked by a Grodd-controlled Sara Lance, Isaac ambushed her from behind and stunned Sara with a fry pan to the head, saving Stein's life. As the Legends left Vietnam, enjoying the secret pie recipe of L. B. Johnson's wife Lady Bird Johnson, Isaac also took a slice of the pie and ate alongside the team, before being noticed by Sara and Stein. Isaac excitedly asked where would their next adventure be, but was promptly mind wiped by Mick Rory, before presumably being sent to his native time period.[1]


  • Genius-level intellect/Master physicist: Isaac was a physicist famous throughout history for his discoveries, which was the reason Martin Stein sought him out.[1]
  • Basic hand-to-hand combatant/Blunt weapons: Isaac could pack a solid punch using a frying pan akin to a mace, leaving Sara Lance unconscious.[1]
  • Stealth: Isaac was able to sneak up even behind a League of Assassins trainee controlled by a telepathic meta Gorilla Grodd.[1]

Behind the scenes

  • Sir Isaac Newton (25 December 1642 – 20 March 1726/27) was a real person, an English mathematician, astronomer, theologian and physicist (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time and a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations of classical mechanics. Newton also made pathbreaking contributions to optics, and he shares credit with Gottfried Wilhelm Leibniz for developing the infinitesimal calculus.
