If there was one thing Lin Xu had always wanted, it was the Shadow Clones. The Shadow Clone Jutsu, invented by the 2nd Hokage, was undoubtedly one of the best techniques in the whole series. It allows the user to retain memories of the clones he created, allowing the user to learn at an exponential rate. However, it came with a great curse, if the user's 'will' is not strong enough, they'll be unable to handle the amount of information forced into their brain when the clones disappear. Bondrewd's Zoaholic is a step further, the user can implant his consciousness into multiple organisms—granting the user pseudo-immorality, but it'll likely drive the user mad unless they have Naruto's stubbornness. Demon Eye: Foresight is great for general uses, but it'll also drive the user crazy from being unable to separate reality from the future if the user cannot handle it. Since Lin Xu doesn't like to fight, he does not need Broly's biology or even the Saiyans for that matter.
