Spo has a very snarky personality, as well as being a loudmouth with a sharp tongue, he usually makes no-nonsense quips at inappropriate times. Though Spo makes off-color remarks and seems to be deliberately trying not to make friends, the opposite is true: he desperately wants a friend but lacks appropriate social skills. While he is intelligent, he is also known to be over-analytical at times, and often rants to Fido in a condescending manner about the nature of things.
