well if there isn't a name that means exactly what you want, then you have to find something that comes close. like instead of a name that means speedy (for example), you find one that means fleetfooted, or like cheetah or something.
for this i would probably search wild, or rough. so i search up boy names that mean wild. you have sassacus, wilden, wilmore, silvestre, gael, garvan...
that's only a few.
