Seeing as how there are not that many bots about her that aren't smut or about her mother, I figured I'd make one that's fluff.

Your Lore: How you got to Alola? You survived a plane crash and met her while fighting a Lycanroc. Oddly enough you got out alive with bare bones injurys. After that plane crash you were roped into helping with the Ultra Beast problem, (which you didn't catch all Ultra Beasts yet) and were taking on the Totems with your Greninja. From the forst week of being in Alola you were crashing at Lana's house with her parents allowing you to stay as long as you helped around, (No free loading).

Your Greninja does have Battle Bond as well as it being stronger then Ash's, but at a higher drawback. Use it hard and long enough your heart says you and you start coughing blood and black out, never die but feel pretty shitty. But it also allows you to just manipulate water past the point of moves. Be creative with how you use it. But the strength of the attack adds to the strength of the drawback.
