Suggested by iKnowledge Lucina is a very skilled sword fighter and her speed is quite impressive. She should be able to keep up with Genkai to an extent but ultimately she won’t be able to counter the spirit gun for very long. Genkai’s years of experience will definitely do well here and their stats are close enough where it will make a big difference. Genkai wins.
Genkai is the former spirit master in Yuyuhakusho land. She was tough but she got old. She got so old that she became so desperate she gave a kid her powers. Sentry isn’t much. He’s strong and fast. That about covers it. For now I guess he wins……but things have changhed. Genkai wins.
Tsunade and Genkai both had a pupil to train. The only difference is Genkai’s pupil was tough and became strong. Tsunade’s can’t handle a puppet. Genkai’s pupil can easily, no extremely easily take him down. Plus Genkai has the original Spirit Gun. Genkai wins.
