Suggested by Sonic Manaphy has some strong water type abilities even if he is completely overshadowed by just about every other water type legendary. That will still be enough to beat Ditto. Ditto isn’t really a combat type Pokemon. He can transform a lot and has access to many special moves but a copy will never beat the original. Ditto has some severe limitations as a result and won’t be able to claim victory here. Manaphy wins.
Suggested by Sonic Mistman is a fairly powerful fighter and I always thought that he looked rather impressive in his quick anime appearance. He has good raw strength but a lack of projectiles is what will hurt him here. Manaphy is hardly the most powerful Pokemon out there but he does have solid levels of speed and a ton of attacks up his arsenal. He can pepper Mistman from afar and the guy’s durability is not enough to hold out. Manaphy wins.
Suggested by Sonic Manaphy may have a lot of different abilities at his disposal but none of them will be enough to turn King Vegeta away. That guy has enough ability at his disposal to quickly blast Manaphy out of there. Especially since he got his Xeno form which amplifies his power thousands of times over. Manaphy just won’t be able to keep up. King Vegeta wins.
Manaphy is a water pokemon of incredible speed. Of course it won’t be enough to stop Ash. Ash is a Pokemon Trainer who may become the master. He has a lot of pokemon and he has even more wins! Manaphy may have lost this match, but maybe one day he’ll be back to pwn. Ash will be back of course. Ash wins.
