Biography Edit

John Robertson was born to Lonnie Robertson (a sculptor) & his wife Brianna (a great dog racer) in the heart of Exeter, England, on October 2, 1854. The Robertson family, however, moved to London shortly after John’s birth. During his childhood, John was aggressive & violent, often squabbling with his schoolmates & picking fights with them. Sometimes he would even pick up a stream of foul words (& that caused his mouth to be washed out with soap constantly). Otherwise, John tried his best to be a good boy, often helping his mother take care of her racing dogs & his father work on his next project.

In 1876, shortly after John’s 22nd birthday, the mouse was visiting an old friend at the Mouse Gypsy Caravan. There, he met a beautiful mouse named Lily. The two fell in love, married 13 years later, & had a daughter, Miranda. John began to support his loved ones by working as a carpenter.

The Robertson family was a very happy one, indeed, until Mouses Fiennes came during the night & brought the abducted Robertsons to his hideout. There, he put a gun to John’s head, & forced John to work as his thug. Lily, however, refused to stoop to Mouses’ level. "I’ll never let my family suffer at your hands, you ugly rat!" she said defiantly. Unfortunately, those were Lily’s last words, as the former Gypsy dancer was bound, gagged, & thrown into the Thames River, where she drowned. A horrified John immediately—& reluctantly—agreed to work as Mouses’ minion. In return, while John was out committing crimes, Mouses would watch over his young daughter Miranda.

John, however, did not have to murder, rob, & rape for long—just a couple of days after committing his first crime, John came across Bill The Lizard, formed a friendship with the reptilian do-gooder, & applied for a position in his group, known as “The Goodie Gang”. John then began to fake crimes assigned by Mouses, all while learning from Bill, the self-acclaimed “master” of disobeying the Boss’ orders.

To this day, John continues to fake crimes for Mouses with the Goodie Gang, managing to squeeze a little time for his daughter & wife, who has risen from the dead (but that’s another story in itself...).

As the toughest member of the Goodie Gang, the stubborn John Robertson refuses to give up on his friends’ mission without a fight. Violently aggressive & hot-tempered, John prefers to solve problems with his fists (if you catch my drift) & will often beat the crap out of someone when in a foul mood; the slightest thing can set this living volcano off, & he’ll do anything to get rid of his rage, mainly by spouting off all sorts of swear-words that would make a sailor blush. And despite the fact that he is a member of the Goodie Gang, John tends to play dirty when it comes to the rules, whether when playing cards with his friend Max or killing one of Mouses’ thugs.

In spite of his short temper, hostile nature, & atrocious cursing habit, however, John is truly an angel of mercy, caring for others like he would his own children (especially those who have been made victims of Mouses Fiennes’ crimes). With a heart of gold & the nurturing instincts of a mother bird, John’s gentle side often takes over his violent one many times.
