A-Feraligatr: water/dragon, cuz it's as much godzilla in design as tyrannitar.
A-Starmie: Water/Ground and is basically a sand dollar (which are related to sand dollars irl).
You know there should be some special Alolan Bellossom. It's pretty much a hula dancer as is. or liligant.
A-Blastoise: Water/Steel, snapping turtle re-design (to include ridged shell, no cannons) with emphasis on higher physical defense and attack. Strong Jaw ability (HA sheer force) and new signature steel type biting move that does one of the following:
A- ignores target def increases, like chip away.
B- breaks through barriers, like brick break
C- Ignores protect, like feint
D- always crits, like frost breath
E- chance to reduce target's Def, like rock smash
