Willem Batiste was the Human name taken by a member of Species 8472 in the later half of the 24th century. Batiste was a reconnaissance agent sent through an inter-dimensional rift to spy on the United Federation of Planets. Provided with an isomorphic compound, to hold off the effects of the reversion for several years, Batiste was able to infiltrate Starfleet Command, attaining the rank of admiral. He is described as a robust man in his mid-50s.
