能

个人认为他的纯血纯观念太强了，应该不会

能进。哈七有个食死徒说过“斯莱特林没几个泥巴种”

分院帽会考虑学生自己的感受，如果他强烈要求完全可以。

Slytherin is one of the four Houses at Hogwarts School of Witchcraft and Wizardry, founded by Salazar Slytherin. In establishing the house, Salazar instructed the Sorting Hat to pick students who had a few particular characteristics he most valued. Those characteristics include: cunning, resourcefulness, and ambition. Many Slytherin students tend to clique together, often acquiring leaders, which further exemplifies Slytherin's ambitious qualities. Examples of these include Draco Malfoy’s Gang and the Death Eaters.
The founder highly valued and favoured pure-blood students and the Sorting Hat admitted that it can be a factor when being Sorted. Students of any blood status can now be placed in the house. However, a Muggle-Born student from that house is considered to be quite rare.

第二段就有說，任何血統的學生都可以進蛇院，只是人數非常非常稀少

第七部中透露了
“好的，好的，看来我们的确抓到了一个小斯莱特林。”斯卡比奥说，“你很幸运，弗农，因为没有几个泥巴种的斯莱特林。你爸爸是谁？”

应该可以

梅林是吗？感觉好久远的设定了，麻瓜出身，大魔法师。

可以吧

老伏虽然爹是个麻瓜 但是老妈是纯血啊 斯内普教授也是老爹麻瓜 老妈纯血 所以混血是可以的 但是貌似不收麻种学生 感觉排外蛮严重的

能，斯内普就是一个混血。

是有的。但是除非你的文笔很好 把控住主角的性格 否则这种设定很难啊

我觉得可以，如果你有斯莱特林的特质并且自身又很希望进入斯莱特林话

镇楼不错

非巫师，应该是非纯血吧
