Breakdown of the Greninja MU:
> Strong nuetral:
- Uncharged Water Shurikens
- Good ground and aerial mobility
- Low stature and crawl, makes Zair harder to land and allows Dtilt to be a moving threat
> Good combo potential:
- Dtilt, Utilt, Nair, Uair, Dair all are combo starters
- Up throw is main combo throw, Up throw -> Falling Uair -> First 2 hits Bair lock
- Dair -> Footstool -> Shuriken stall -> repeat/Bair lock
> Good kill power:
- Dtilt confirms into Usmash, Fair
- Usmash sweetspot and covers large area
- Fair has good range and power
> Other:
- Shadow Sneak can be used to escape for combos or multihit moves
- Shadow Sneak can also influence ban on FD because it's difficulty to see
- Fully charged Water Shuriken does not clank with Link's projectiles
- Hydro pump can gimp easily if Link is not careful
> Weaknesses:
- Standing grab is extremely slow (f14?)
- Fast faller
Overall, Greninja is similar to Fox and Sheik where Link will struggle win neutral and try to keep them out once they break his zone. Greninja simply framedatas Link, coupled with the fact that Link can be easily comboed by Greninja's bnb combos and footstool shenanigans, it's a pretty difficult MU, relying on Link to simply outplay Greninja.
