Johnny Walker has ruled out any possibility of facing half-brother Valter Walker inside the UFC octagon.

The Brazilian heavyweight told MMA Fighting that the sport's violent nature makes a family matchup unthinkable. Walker dismissed the scenario outright, saying he enters the cage to inflict damage on opponents but draws the line at harming a relative.

Walker described the mental shift required once fighters enter competition as incompatible with facing family. "When we step in there, man, it's one guy trying to kill the other," he said, per MMA Fighting. Once competitors sign contracts, they accept that reality — but applying that mindset to a sibling crosses a threshold Walker will not approach.

The heavyweight acknowledged complications in his relationship with Valter. The two have shared training time in Russia, though Valter's tendency toward provocative humor has created friction between them. Walker said his half-brother's jokes often cross into disrespect, making closeness difficult to sustain.
