Damn that's ****ed up if it is TenTen. The writers mean as hell yo. It's bad enough Rock Lee ol' downs syndrome chakra having ass has to be the dad..but of all the moms there could've been for Metal Lee, you had to give him literally the MOST fodder female in the series?
The other nigglets getting byakugans, sharingans, special chakra, all types of shit from they folks, and this lil ***** Metal gets to inherit hard work and ninja tools. ****ed up man. They know they could've invented a character to be the mom instead of adding fodder genes with handicap genes to make a baby. *****s unlocking sage mode already and shit and they gave this ***** a sword and hand-to-hand combat. He's a glorified Samurai
I mean really! What genius said "I've got a great idea. Why don't we make the guy who couldn't utilize chakra have child by the chick who only uses ninja tools. That way, the child will be an awesome ninja who can only use taijutsu and ninja tools in a story about shinobi with chakra! Yay!"
