Ra
    Ra is the villain in the original Stargate movie, and is established in the television show Stargate SG-1 as a Goa’uld. The character is based on the Ra of Egyptian mythology. He is played by Jaye Davidson in the film and Jay Williams in the series. In some scenes of the movie, the outline of Ra’s original humanoid form can be seen. This contradicts Stargate SG-1, in which Ra’s species are serpentine parasites.

    According to Stargate mythology, 10,000 years ago Ra voyaged across the galaxy searching for a new host that could sustain his dying form. He discovered Earth and found the native humans easy to repair using his advanced technology. He possessed the body of a young boy, and ruled over the planet as a god. During his reign, he seeded humans throughout the galaxy using the Stargate. Ra was the most powerful and cunning of the Goa’uld, holding the title of Supreme System Lord.[47] His Queen was Hathor , his son was Heru-ur, and his brother (and enemy) was Apophis. Ra also defeated the Tok’ra Queen Egeria, and battled the Goa’uld Shaq’ran.

    Five thousand years ago, the people of Earth rebelled against Ra and buried the planet’s Stargate in Egypt. In order to avert another such uprising, Ra outlaws reading and writing on his other planets, including Abydos. In the Stargate film, an Earth team led by Colonel Jack O’Neill travels to Abydos after the Stargate is activated, to reconnoiter the area and if necessary close the way to Earth with a nuclear bomb. They are captured by Ra’s forces upon his return to the planet. Ra plans to send the bomb back to Earth along with a quantity of naqahdah, which will amplify the explosion. O’Neill and his team escape and eventually incite a successful rebellion amongst the Abydonians. As Ra abandons the planet, O’Neill and Jackson teleport the active bomb to his ship by way of a ring transporter, destroying it and him. Ra’s death draws the attention of the other Goa’uld to Earth, and creates a power vacuum amongst the System Lords that allows Apophis to become more powerful.

    Ra has only appeared once on Stargate SG-1, in masked form, in the season 8 episode “Moebius”. In that episode, SG-1 travels back in time to steal a ZPM from Ra, and inadvertently changes history into one where Ra took the Stargate with him after the rebellion on Earth. The original timeline is restored after a second version of SG-1 travels back and ensures that the Stargate is left behind.

    Ra是星际之门电影中的反面角色，作为一个Goa’uld出现在电视剧”星际之门SG-1”中。该角色基于埃及神话里的太阳神Ra。在电影中他是由Jaye Davidson扮演的，在电视剧中他则是由Jay Williams扮演的。Ra的原始人类形象可以在一些电影场景中看到，这和星际之门SG-1是矛盾的，因为星际之门SG-1中Ra的种族是蛇形寄生生物。
    根据星际之门神话，10000年前Ra在整个星系里航行，寻找一种能维持他奄奄一息生命的新宿主。他找到了地球，发现使用他的先进技术可以轻易修复地球人类的身体。他占有了一个年轻男孩的身体，以神的身份统治着这个星球。在统治期间，他通过星际之门将人类送到星系的各个地方。Ra是最强大和最狡猾的Goa’uld，被冠以最高系统领主的称号。他的王后是Hathor，他的儿子是Heru-ur，他的兄弟(也是敌人)是Apophis。Ra击败了Tok’ra王后Egeria，和Goa’uld Shaq’ran进行过战争。
    5000年前，地球人反叛Ra，掩埋了星球上埃及的星门。为了防止类似的叛乱再次发生，Ra宣布在他的其他星球上禁止识字和写字，包括Abydos。在星际之门电影中，当星门激活后，一只由Jack O’Neill领导的地球队伍旅行到Abydos侦查该地，如果必需的话，用一颗原子弹关闭到地球的星门。当Ra重返Abydos时，他们被Ra的军队俘虏。Ra计划将这颗炸弹加装一定数量的可以增强爆炸威力的naqahdah，送回地球。O’Neill和他的小组逃了出来，后来在Abydos人中成功激起了(对Ra的)反叛行动。Ra放弃了这个星球(准备逃跑)，O’Neill和Jackson通过一个传送环远程将已激活的炸弹送到了Ra的飞船上，摧毁了飞船，杀了Ra。Ra的死引起了其他Goa’uld对地球的关注，也在系统统治者中形成了一个权力真空，使得Apophis变得更加强大。
    Ra仅仅在”星际之门SG-1”中出现过一次，他戴着面具在第八季的”Moebius”中出现。在那集里，SG-1旅行到过去，去从Ra那里偷一个ZPM，却无意中将历史改变到地球暴动后Ra取走星门的状态。在第二个SG-1小组返回后，原始时间线被复原，星门也保留在了地球。
