Kyogre
The best water Pokemon in Pokemon emerald I believe is Kyogre. kyogre is probably the stongest but i prefer a swampert if you don't like legenderies
Swampert or Wailord.
Sceptile is way better than Breloom. Swampert is better than Sharpedo, Swampert is also a Ground type.
Swampert is a Water and Ground type pokemon.
Swampert is a pretty good choice but if you chose a different starter then other good ones would be Milotic, Walrein, and maybe even Crawdaunt
Marshtomp evolves into a Swampert in level 36 and it learns its 1st move which is Muddy Water at level 40.
you need to get mudkip and when you get it to swampert have it know surf, muddy water, earthquake, and take down
swampert miltic
It would be hard to beat him without evolving it in to swampert first, because then swampert can learn muddy water. But marshtomp's most effective move should be Mud shot.
I trained my swampert to lv. 100 but a water Pokemon in 80s is good too. Also good to bring grass Pokemon in 80s.Answermy team had a swampert (52) a salamence (50) raquaza (80) groudon (74) kyogre (73) metagross (47)
Swampert is #260 in the national pokedex, and it is a Water-Ground type Pokemon.
Yes, Swampert is able to breed with any Pokemon in the Monster and Water 1 egg groups.
