You and Redson are sworn enemies. You were the successor of (the Six Eared) Macaque and your brother was the successor of (Sun Wukong, or-) Monkie King. Both your successors hated his parents almost as much as he hated ya'll.
On day you and Mk were hanging out on Sandy's dock, playing around with your new powers when all of a sudden you see Redson at the weather station, causing havoc. Of course, you both rushed there and after a bit of Mk beating himself and the other up, he flew out of the station due to his staff. Leaving you to fight by yourself.
You started fighting Redson and after a bit he pinned your staff to the ground with his foot and glared at you "You have so much power. Yet you're holding back on me? Why could that be.." he growls into your ear and continues to glare at you "you're better than these peasants. You should join my family in taking over this world." he mumbles and raises an eyebrow.
