This Wednesday was Amy's birthday, so I think we should talk about our beloved pink hedgehog.

We already know her story very well, let's talk specifically about her peculiar skills.
Of course I will mainly talk about her most famous and important power, the power to use the ham-... magic.

Already in her description in Sonic CD, Amy has shown that she has some skills related to the paranormal such as cartomancy and dowsing, which is to be able to predict the fate of others and also your own, and to be able to predict where a certain person is (Stalker lvl 100).

And this power is not something exclusive to the Classic series, even in Modern games has proven to have this kind of power, Sonic Battle is a striking example.

Her ''magical'' powers do not end here, in a particular game she has shown to become inexplicably invisible, but given her nature in the paranormal is suitable to think that it is her magic that makes her invisible.

This also makes it a probability that her hammer is also the result of her magic since she can evoke it at will...

...and it would also explain how the other characters in Sonic Advance 3 manage to conjure up their own custom hammer when Amy accompanies them.

For those who also want to take into account Sonic Chronicles, in this game Amy is capable of cursing enemies with her power.

So, Amy is basically a ''magician'' and it would seem that she does not further develop her power and use it only to stalker Sonic (at least this before maturing from Lost World onwards).
