ok i will give u 3 hints to a person and u have to guess who it is and then make up your own 3 hints to a new person.
oK here is mine>
1) His father is a death eater
2) He is one of Draco's friends
3) Ron use the polyjuice potion to turn into him

I'm sure it is Goyle, because Crabbe doesn't usually appears in Harry Potter games (at least in the GameCube games, because I think he appeared in the GameBoy Advance series...).

Yeah same here.

I think its Crabbe, isn't Crabbe the shorter, fatter one out of the two goons? Thats the one Ron turned into at least... that is the deciding factor in these hints...

atticus is right, it was crabbe, i guess i should've mentioned that the names of the people don't have to appear in the game, the names just have to be associated with the harry potter series

here's another one :
1)half-giant
2)female
3)She is from france

the one headmaster that comes from the one school during the Triwizard Tournement .. thats all I remember ...

Madame Maxime

darn i knew this one too

ok, here's one:
1) Has a cat
2) is a Male
3) he is the caretaker for hogwarts

That would be Filch.
1) Animagus
2) Writer
3) Has a magical pen

Rita Skeeter.She has the wierd quick quotes quill, and she is a writer for the daily prophet or used to be later, also she is an animagus since she can turn into a beetle.Illegaly though.

That's right. Lets see...
1) Professor at Hogwarts
2) Part of the Wizengamot
3) Gives cruel and unusual punishment for Detentions

I think...Professor Umbridge with that righting on the hand thing that makes you bleed and cuts your hand, and I think she was in the Wizengamont since she was present at Harry's hearing.

That's correct. Here's another one: (This one is a magical creature, NOT animagus!)
1) Only one leg
2) Carries a lantern
3) Non-materialized without the spell Lumos
