Agrajag

The Agrajag is a creature which, by coincidence, gets killed by Arthur Dent hundreds, maybe thousands of times. Arthur Dent is, either directly or indirectly, responsible for his death in some way. He is first seen notably as a bowl of petunias. At this moment all we know about him are his thoughts: "Oh no, not again". After which many people speculated that if we knew exactly why the bowl of petunias thought this, we would know a lot more of the nature of the Universe than we do now. The reason Agrajag said this is because he was killed by Arthur in many ways before.

Agrajag built a large, and particularly malicious looking statue of Arthur with multiple arms and feet, swatting flies, squashing ants, and even using one of them to summon into existence a bowl of petunias. Agrajag confronts Arthur in a cave he lives in, in the form of an ugly batlike creature. Later on, Agrajag is called Stavro Mueller, and has started a nightclub called Beta, where Arthur and the others are now gathered. Agrajag tries to use this oppurtunity to kill Arthur, but Arthur dodges a bullet from another place, and it hits Agrajag instead. Agrajag blames Arthur for his many deaths, as Arthur has been there every time in every incarnation, and always, in some way (usually indirectly) responsible for his death. Agrajag hates Arthur with a passion and believes he is out to get him, although it is all one giant coincidence, along with hundreds of others that go on throughout the universe. It is possible that this coincidence, along with all of those others were caused by the improbability drive, as tampering with improbability physics causes things like that to happen all the time.
