Bruce

John's Gabite (Jon's Fukumaru), nicknamed Bruce, is the fourth Pokemon obtained by John. He caught Gible inside Wayward Cave whilst exploring with his friends. He was a rough Pokemon to catch as he attempted to avoid and attack the gang. John eventually caught him, and following this, he became a stubborn, although promising member of John's team. Eventually falling in love with a Pokemon John and Gible help heal and capture, a Seviper named Ruby, Bruce was only shot down and slipped into depression, John often referring to Bruce as being emo. Eventually, Bruce and Ruby fell in love and Bruce's attitude and personality bettered and he became a cheerful Pokemon, and a powerful and reliable battle. During the Sinnoh League, Bruce evolved into a Gabite while battling Cynthia's Garchomp, and gained Ruby's attention finally.

History
John and co. first met Gible on the Cycling Road where he stood in their path and used Earthquake, knocking them off, and destroying, their bikes. He later used Double Edge on John, causing both of them to fall off the Cycling Road, roll down a cliff, slam into a tree and fall into the Wayward Cave. There, John attempted to learn why he had attacked them, leading to a chase that resulted in John getting attacked by Geodude's, Graveler's, a Steelix and having a minefield of Voltorb's and Electrode's explode and electrocute him.

He later caught up with the Gible and learned he was just a mischeivous Pokemon that loved to cause trouble. He challenged he to a battle, defeated him, and caught him. He has a hot temper and often refuses to listen to John, opting to attack him instead. He has a few times where he listens to John, but only during a rough battle where a Pokemon starts to defeat him, only listening to defend his own honor.

Upon meeting a Seviper at Lake Valor, that he and John healed and later captured, Gible fell in love with the Seviper. Ruby originally did not return Bruce's feelings, making Gible a bit depressed for a while, opting to attack John whenever he attempted to comfort him. Eventually, Bruce defended Ruby at Spear Pillar and the two fell in love and Bruce's attitude and personality bettered immensely, listening to John now.

Bruce became a vital asset against Volkner, and even in the Pokemon League, where, most notably, he evolved into a Gabite, defeating Cynthia's powerful Garchomp.

After the league battles, John decided to start off in a new region with a clean slate. So he left Bruce, alonside his other party Pokemon, at his home in Twinleaf Town before setting off with his baby Mijumaru, nicknamed Blue Moon, to the Isshu region with his friends.

Moves used
Gible used to know the move Double-Edge but it was replaced by Fire Blast.
