Hybrids might have the same talent for fighting that Saiyans have, but they seem to have the mentality of Earthlings, not Saiyans. Gohan, Future Trunks, and Future Gohan didn't seem to have any interest in fighting beyond it being a necessity. Trunks and Goten seem to like martial arts/fighting but only to the level that normal 7/8-year old Earthling boys would. Hell, Goten seems to care more about toys than he does fighting and Trunks would rather go to the park than train. For most Saiyans a pure Saiyan Masque wouldn't do anything for them, but for Kakara whose pacifistic mentality is holding her back in regards to learning combat stuff, would the biological desire and need to fight that pure Saiyans have mitigate/override/cancel out the mental block?
