There is no purpose for it. Pokemon wanted to make magikarp the weakest Pokemon in the world but all Pokemon still need to have at least one move so they designed splash. The move does exactly nothing exept wastes a turn. Use an exp. share on magikarp if you want to level it up.
splash, tackle, flail, and bounce
splash,tackle,flail,bounce(tutor)
lv. 1 magikarp, lv. 1 magikarp, lv. 1 magikarp, lv. 1 magikarp, lv. 1 magikarp, lv. 1 magikarp Oh and remember that they all have to know how to splash!
MagikarpActually, Magikarp can learn moves and level up. Magikarp can learn Tackle and Flail. Feebas can also learn Tackle and Splash. Magikarp and Feebas can't learn any more moves until they evolve into Gyarados or Milotic.
wailmer and magikarp are the only that learn it that i know of
magikarp Lvl. 4 ralts combee Lvl 4 Abra W/O hidden power ditto (not actually that bad) unown magikarp, magikarp, magikarp,magikarp, magikarp, and magikarp, all level 1 and all they have is splash. you cant do anything but die...
Splash wont do anything AT ALL!!!!! people just wanted magikarp to be the weakest Pokemon of all time. :)
battle them half of them probably only have splash
nothing,only uses splash
(Pardon my spelling mistakes) The Only Pokemon that can learn splash is Magikarp, Gyardos (if you didn't make it forget splash when it was Magikarp). The other two I THINK is Feebas And Milotic (Milotic's reason is exactly the same as Gyardos. Hope this helped! :)
Magikarp and Shedinja. Magikarp because it can only learn splash, tackle, and flail. Shedinja because it can only have 1 hp for its whole life.
ANSWER:The weakest attack is splash. It does absolutly nothing. But i think it is a good move for a cute contest. I will have to check again. p.s. the Pokemon most likely to have this attack is magikarp. If you want to get a magikarp with this move you should use an old rod at any body of water. The Pokemon You reel in will definitly be a magikarp only knowing splash until it gets to a certaint level (I'm not sure which) it will learn tackle. MAGIKARP LEARNS SPLASH AT LV 1, TACKLE AT LV 15, AND FLAIL AT LV 30.
