these are an idea for the starter water type. i don't think it would ever become the starter but, nya... ideas
anyway

left one:
dropeep: water
male: 50% female: 50% (because 50 is better)
ability: (may change) torrent
ht: 1"8' wt: 5 lb
this pokemon is an okay swimmer and can dive 10 feet down with no problems. they are still reliant on their guardian until they evolve.

mid one:
(name may change) harrenile: water flying
male: 50% female: 50%
ability: (may change) torrent
ht: 2"4' wt: 20 lb
this bird pokemon isa superb diver and can dive as deep as 300 feet if they try. they are also very accurate when catching a poor unsuspecting magicarp.

right one :
Kingull: water flying
male: 50% female: 50%
ability: (may change) torrent
ht: 4"6' wt 77 lb
this pokemon is highly thought of for it's beautiful beak, feathers, and powerful wings. they also have very high accuracy that could rival even Braviary's.
