Freyr isn't an overly complex character but he comes up with rather complex and pointless plots. He heavily prefers theatrics and dramatics. The more convoluted it is, the more he likes it. This could be because of his romantic nature and the sorts of things that tend to be romanticized. This basic trait can easily be seen by the fact he has decided his human world persona would be a Phantom Thief. His reasoning for this was because Loki was acting as a detective, and since he would be Loki's rival, and a phantom thief is a detectives rival, he would become one himself. Of course his reasons for being up against Loki are paper thin, and half the time he seems to be more playing a role than using the role for a particular goal.
Another example of his over exaggerated romanticism is his falling in love with Mayura, Loki the main characters assistant, at first sight. He decides from this one off encounter that she is the perfect Japanese woman and from that moment on (despite learning her name and hearing it many times) calls her Yamato Nadeshiko. He is determined to steal her heart and marry her. He pretty much forgot everything else he was doing after this, which was pretty much one of the first things that happened after he was introduced.
Besides having ridiculous ideas of romanticism and defining his life as if he were living a play or was a character in a fictional novel Freyr is also pretty air headed. It's hard to say if he's outright stupid, because he is capable of some clever things (though perhaps creative is the more appropriate word for it), however lots of simple things confuse him, he is quick to distraction and seems to be incapable of taking anything very serious for very long. On the other hand he will take stupid things no one should seriously and can't let go of it. The only thing he does take legitimately serious is his sister Freya and her safety. But even then he has shown to forget about her and his worry about her frequently.
Originally Freyr teamed up with Heimdall who was ordered by Odin to put a Rune on Loki so he could not return to Asgard and pretty much make Loki's life hell and horrible. But this was all Heimdall's idea as there was a grudge between them. Odin also ordered Heimdall to deal with Loki. Freyr's only concern was the fact that Freya was said to be on Earth somewhere and potentially a target of Loki's. Worried that his precious sister would get corrupted by the trickster god he wanted to find her and save her before Loki could do something wrong.
In the end Freya is fine (and is in love with Loki so she doesn't like people attacking him), Freyr the moment he sees she's okay is fine with it and then carries on as usual. It was pretty much a "Oh hey there you are Freya, I'm glad you're okay! Now back to stalking Yamato Nadeshiko and being a Phantom Thief!" which sums up his general flow of personality pretty well.
There are a few moments later in the Ragnarok part of the series where he is shown to be more aware of Odin plans than everyone else, he seems to not agree with whatever Odin is up to, but follows his orders anyway. These are the moments where we really do see more than the fumbling fool.
On a day to day basis Freyr is pretty friendly and polite. He won't bother people if he thinks they are busy, he won't be intrusive (unless he's stealing something as a phantom thief), and he won't do things to upset people, at least willfully. (His personality however is one that has a tendency to irritate but he's not acting that way on purpose.) He values his word over everything else and is rather honest for someone who's decided to take a thief role.
