Jean Henri Fabre first appears in the beginning of the first episode, when he attempts to steal the "Immortal Beloved." He rides a giant mechanical grasshopper and can control bees and other insects to use as weapons. Like the insects he studied, juvenile Fabres are shown moulting from one form to another, growing from child to adult in a few days. Two Fabres are shown in the series; the first Fabre apparently dies by crashing into a Tokyo office building, but actually moulted and escaped, taking the form of a child until he fights and is killed by Drake Anderson within the I-Jin base.
