Online profiles mention that if Joey was capable of talking, he would deliver an inspirational speech discussing the destiny of victimized cockroaches. He is noted to hope to sometime gain absolute control over Oggy's residence for the cockroach civilization and not just himself. He is proven to have a short temper, as shown when Jack's snoring got on his nerves, and also grows annoyed when his leadership is objected. Despite this trait however, Joey is frequently portrayed as "the brains" of the trio and is shown to regularly formulate new strategies. He is tech-savvy, as shown in "Oggymon Go" when he hacked into a game site without a hitch. In addition, he is guileful and willing to carry out practically anything to obtain what he wants. This includes but is not limited to manipulating others, cheating to win, etc. However, for all that, Joey can experience moments of foolishness, and one could say he is "clever but not wise". This is arguably best shown in "Fly to the Sun" when he was incredibly slow to realize it was life-threatening that Oggy's house was approaching the sun. Also, he is stated to think in black-and-white terms.
Joey is proven to be the cruelest and most sadistic member of the roaches. This trait is displayed in such actions as cheerfully recording a swamp monster "preparing to harm" Oggy while Dee Dee and Marky were visibly horrified ("Scaredy-Cat"). Even though he is the self-declared leader of the gang, Joey is shown to be highly self-centered. On occasions, he has even attempted to send Dee Dee and/or Marky to action in his place, e.g., "Mission Oggy" and "Crackdown on the Fridge". What's more, he is shown to be money-grabbing. In his efforts to acquire cash, Joey has stolen a pharaoh's sarcophagus, tried to abduct a baby, attempted to steal a celebrity's diamond, among other things. He is additionally more vindictive than Dee Dee and Marky; ex. putting forward the idea of payback in "Masquerade". Plus, his anger tends to be the driving force behind his retaliation plans (like in "House for Rent " and "The Tenants"). On top of this, Joey can bully Marky and Dee Dee in later episodes, yet he sees nothing wrong with this. Despite this characteristic however, he genuinely cares about them. In "Sacrificial Special", he grew angry at Oggy after he had suggested Bob to sacrifice Marky. He was clearly happy to see that Dee Dee was fine after a projection of Oggy grasped him ("The Cockroaches' Awakening"). (There are numerous other examples as well.)
While being recorded in "Fake News", Joey acted like an innocent, unfortunate, and helpless individual who was cruelly tormented by Oggy. However, this was unquestionably a facade to convince the public into thinking Oggy was victimizing the cockroaches. Then again, Joey was not completely off the mark, or at least to an extent. After all, there are instances in which Oggy has attacked Joey (and the other cockroaches for that matter) without reason, like in "Airship House". Not to mention the cat can commit foul actions against the trio, like attempting to kill them without motive in "Docu-Mentally". In spite of Joey's enmity with him, he tends to bond with Oggy more than Dee Dee and Marky.
In "Ugly, Dirty and Good", after receiving an injury to his head, Joey began to act quite childish and also forgot about Dee Dee and Marky in every respect. He additionally acted exceptionally friendlier to his "father" than usual. After he ultimately retrogressed to his primitive personality, Dee Dee and Marky later found him tenderly gazing at Oggy.
Joey is a short, pink-bodied, purple-headed anthropomorphic cockroach roach. He wears white gloves and has a pink right eye and yellow left eye or red right eye and yellow left eye(sometimes the artists incidentally switch them).
