Professor (Felix the Cat)

The Professor was the on-and-off adversary of Felix the Cat who was first featured in 1959 - he is not always an outright malicious individual but he sees Felix as a source of constant fascination due to his obsession with Felix's magical bag of tricks.

A mad scientist by trade the Professor will stop at nothing to steal Felix's bag of tricks and has fought the mischievious feline on several occassions - though the two are not always outright enemies.

The Professor is the uncle of Poindexter but unless his nephew seems to prefer to use his scientific genius for selfish (sometimes outright evil) means - though The Professor can use his genius for good at times.

The Professor doesn't always work alone either, sometimes he employs the help of Rock Bottom - a bumbling minion who often tries (and fails) to aid The Professor in obtaining Felix's bag of tricks.
