溫斯頓是一隻受過基因工程改造、智力超絕的猩猩。他是一位優秀的科學家，同時也是代表著人類潛能的一位勇士。 人類重新開啟太空探索的第一步，就是建造地平線月球殖民地。居民中有一群基因強化過的猩猩，目的是為了要測試在太空長期生活的適應能力。 在接受了哈洛‧溫斯頓博士團隊的基因工程之後，其中一隻猩猩產生腦部快速發展的現象。博士不僅教他科學，還以人類創造力的故事來啟發這隻猩猩。而這隻年輕的猩猩就在協助科學家進行實驗的生活中度過每一天，同時看著窗外的藍色世界，夢想著在地球上他所擁有的無限可能性。 不過其他猩猩領導的反抗行動使這隻猩猩的生活陷入一片混亂。其他猩猩殺掉了科學家，並且將殖民地占為己有。於是這隻猩猩決定繼承這位照顧他的科學家名字：溫斯頓，並且建造臨時火箭逃往地球。在地球，他找到了新的容身之地：捍衛者，一個代表著他所仰慕的人類天性的組織。溫斯頓最後終於能夠實現他的英雄理想，那個從小就一點一滴累積起來的願望。 現在，隨著捍衛者的解體，他再次和他所相信的一切失去連結。溫斯頓隱居了起來，期待著英雄得以回歸的那一天到來。

Winston was initially a subject in the tests on genetically enhanced gorillas that took place in Lucheng Interstellar's Horizon Lunar Colony. He had shown unusually rapid development, so Dr. Harold Winston, from whom Winston got his name, took personal care of him. Through him, Winston learned science and helped in the doctor's research. The doctor also gave Winston his signature glasses. When the other gorillas started to revolt against the colony, Winston escaped to Earth.
Winston found a new home as a member of Overwatch. There, he became both a soldier and a scientist. His skill in combat led to him defeating Doomfist, and his craftsmanship helped him save the life of Tracer by building her chronal accelerator.
After the collapse of Overwatch, Winston and Athena retreated to Watchpoint: Gibraltar, from which he launched a satellite drone in the event that Overwatch would need to be recalled. He included with it a personal message to the former agents.
Winston is shown to be a gentle giant, never wanting to inflict unnecessary harm on innocents and often stuttering whenever someone compliments him. He really cares about the members of Overwatch to the point of calling them family in the Are You With Us? cinematic teaser. He also seems to have a love for peanut butter and bananas.
Winston is also rather smart when it comes to craftsmanship, as shown by his ability to create the chronal accelerator. He's considered an intelligent scientist as well, and hates being called a monkey.
- Winston is a highly mobile tank that leaps around, creating chaos.
- He works best when moving around, thus is different from the standard stand and plant tank.
- Winston is an effective counter to many agile, low-health, heroes such as Widowmaker, Junkrat and Mercy. His Tesla Cannon does damage in an area and does not require aiming, meaning even the most agile heroes have trouble avoiding it. The short cool-down on jump allows him to launch into the enemy's back line and wreak havoc among low-health targets. It also allows him to easily follow those targets that attempt to flee.
- Pointing straight up before using Winston's jump will make him jump extremely high, and he can still be moved while jumping as other characters can.
- When fighting an enemy, move in and out of your bubble, blocking their attacks while keeping them in range of your Tesla Cannon.
- Winston's bubble blocks shots going out as well as in. It can limit the range of entrenched enemies or turrets.
- Winston and his storyline may be a reference to The Planet of the Apes movies.
- Winston is voiced by Crispin Freeman, who also voiced Roy Harper(Speedy/Red Arrow/Arsenal) in the cartoon Young Justice, as well as Itachi Uchiha in the anime Naruto. He also voiced several characters in Blizzard's other IP, World of Warcraft, the most notable being Vindicator Maraad in the Warlords of Draenor expansion.
- Winston's name and origin may be derived from Winston Scott, an American astronaut who was assigned as a specialist with the STS-72 Endeavor. Winston's versatile jump pack also alludes to this, as the crew of the Endeavor was tasked with conducting multiple EVA walks in preparation for the International Space Station.
- Winston is very similar to Marvel Comics character Hank McCoy aka Beast, an animalistic person with great intellect.
- r3991n is Winston's ID number from his lunar colony
- The voice line "Houston, we have a problem" is a direct unedited quote from the movie Apollo 13 that has become not only symbolic for NASA but a staple in pop culture, the line however is incorrect. The correct line is "Houston we've had a problem".
