User blog comment:Torquil/What should Luffy's gear 4 be like? ?(If you think he is going to get one...)/@comment-3075024-20121215192320/@comment-5826675-20121225050147

conddisering the fact that after only expanding one/two of his body parts luffy becomes so tiny (G3), you can just imagine wht would hppen if he expamded all his parts> the side efffect would make him microscopic> therefore i do not think that this such a good idea
