Poindexter is a boy genius scientist with an IQ of 777. He is most comfortable speaking in complicated scientific jargon. But when he is misunderstood (which is often), he sums up the context of what he is saying in 3 or 4 simple words. Poindexter can invent almost anything in minutes using whatever random objects happen to be near him. He is shy, but kind and always willing to use his wealth of talent and wit to help out a friend.
