Considering I just finished replaying Crystal, I'm gonna reserve Poliwag
, the other Pokemon I used in addition to Chikorita and Abra.
But this leaves me with a question. Will you take separate entries for Pokemon different between games? Examples including Poliwag and Growlithe being available much earlier in Crystal.
for High/Mid tier
Very Early in Crystal, Early in GS
Fast, fairly strong and bulky once evolved
Decent. Surf + Ice Punch is about all it needs
Fairly strong, gets some powerful moves early. Requires a bit of grinding to get past the "Bubble stage", but still useful.
Water-types are always useful
Doesn't excel against any boss in particular (except Brock and Blaine in Kanto), but doesn't really lose to anything.
for Mid tier
Fast, with high Attack backed by decent bulk
limited to Normal moves and Iron Tail (and later, Earthquake)
Quite strong, Strength/Headbutt can bust through most things that aren't Rock- or Steel-types. Once it finally gets Earthquake, good luck stopping it
Fighting-types are not particularly common in-game, so it's good typing
can't touch Morty or Jasmine, loses to Chuck, and doesn't excel against anyone in particular. Not the most useful, but still not bad
