A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing.

If a ninja shapeshifter copies pan ku's abilities and then steal someone does the ninja shapeshifter revert back at the end of the turn, and return the card it stole?
Second part of this question, since the wording on the card requires P'an ku to leave play or be unbowed, and ninja shapeshifter was never named P'an Ku to begin with as long as the original P'an Ku is bowed could you just keep capturing people with ninja shapeshifter?

When you copy an ability with the Ninja Shapeshifter, any words in the ability that refer to the original Personality become "Ninja Shapeshifter" for the purpose of the ability.
When Ninja Shapeshifter uses P'an Ku's ability, it reads "Limited, Ninja Shapeshifter may remain bowed. Take control of a target Personality with more Madness tokens than printed Personal Honor and remove those tokens. The target will not commit seppuku until Ninja Shapeshifter straightens or leaves play. After Ninja Shapeshifter does, give control of the target to his owner." When this ability is used, it gives Ninja Shapeshifter the ability to remain bowed until it straightens, even if Ninja Shapeshifter loses the ability. So you can keep the card.
Since the ability changes the name, the second question isn't pertinent to the way it works.
