Boss Fight
Leader Lt. Surge $6360
Raichu   Lv. 51
1,332 EXP
Electrode    Lv. 47
1,510 EXP
Electrode    Lv. 47
1,510 EXP
Magneton    /  Lv. 47
1,621 EXP
Electabuzz   Lv. 53
1,771 EXP
Raichu may open up the fight with Double Team, so don't waste too much time setting up
otherwise you may not be able to hit the speedy Raichu!
Most of his Pokemon utilize a similar strategy and also share the move Shock Wave as well,
which is a fairly weak Electric-type with perfect accuracy.
Ground-type Pokemon will have a blast here, as most of Lt. Surge's Pokemon's attacks will
be ineffective or, in the case of his Normal-type attacks (Quick Attack, Selfdestruct,
etc.), won't hurt that bad.
None of his Pokemon really have a lot of powerful moves though and the annoying factor is
really the only thing you need to watch for. Don't let his Pokemon's levels intimidate
you.
After beating Lt. Surge, he'll give you the Thunder Badge, as well as TM34 (Shock Wave).
Now that you've gotten your first of the Kanto Gym Badges, make your way north to Route
6!
Boss Fight
Leader Sabrina $6600
Espeon   Lv. 53
2,236 EXP
Mr. Mime   Lv. 53
1,543 EXP
Alakazam   Lv. 55
2,191 EXP
Sabrina may not have as many Pokemon on her team as Lt. Surge, but they're much better
trained and more difficult to take on.
She'll lead the fight with her Espeon, which has Calm Mind and Psychic, so be very careful
not to let it use more than one Calm Mind, otherwise it will be doing a lot of damage to
you with Psychic! Thankfully, it will likely try to use Skill Swap first, which switches
its ability (Synchronize) with your Pokemon's. It's not really a big deal most of the
time, though, but just keep that in mind.
Actually, all of Sabrina's Pokemon have Skill Swap. And you'll probably appreciate it when
she uses it.
Her Mr. Mime is a bit more of a pain. Even though it doesn't hit as hard as Espeon or
Alakazam, it has Light Screen which makes it so your Special-based attackers really don't
have a chance at all, and it also has fairly high Defense and Sp. Def as is. It can
utilize Mimic to copy the attack you just used as long as it stays out. Thankfully that's
about it. Use attacks like Bite or Crunch if you can, otherwise your strongest
Physical-based attacks.
Lastly is her Alakazam, which has Reflect, but it has such low Defense that you're still
going to be doing a lot of damage with your Physical-based attacks. But it will hit very
hard with Psychic when it uses it. Energy Ball can also take some of your Pokemon
off-guard if you're not careful. Fortunately it does not have Calm Mind like Espeon does,
but it does have a Sitrus Berry to heal its HP when it becomes weak.
After beating Sabrina, she'll give you the Marsh Badge, as well as TM48 (Skill Swap). Not
really worth it, but oh well, at least you now have your tenth Gym Badge and the second of
your Kanto Badges.
From here, there are several different places you can go. It's suggested that you make
your way west towards Celadon City and then wrap around south to Fuchsia City.
Boss Fight
Leader Erika $6720
Jumpluff   /  Lv. 51
1,923 EXP
Tangela   Lv. 52
1,849 EXP
Victreebel   /  Lv. 56
2,292 EXP
Bellossom   Lv. 56
2,208 EXP
Erika's Jumpluff might want to use U-Turn against you after setting up a Sunny Day to
boost all of her Pokemon's Speed (thanks to their Chlorophyll ability), so be wary of
that! A quickly fired Fire-, Ice-, or Flying-type attack should hopefully take Jumpluff
out before it can pull it off, but don't count on it if it's not from a zippy Pokemon.
Tangela isn't all that threatening, but its high Defense can make it a little cumbersome
to take out if you aren't using Special-based attackers. Other than that it isn't anything
fancy, but Sleep Powder may annoy you.
Victreebel has the powerful Leaf Storm to inflict massive amounts of Special-based damage,
but it'll lower its Sp. Atk sharply afterwards so it won't be too much of a threat after
that first hit. Having something resistant to Grass-type attacks will prove invaluable
against both Victreebel and Bellossom.
Speaking of Bellossom, it's a little sturdy and capable of using Synthesis to heal its HP
by half  or 2/3 when the weather is Sunny out. Not only that, but it also has a Sitrus
Berry to heal its HP when it gets weak. It will be a pain to take out, but again, Pokemon
resistant to Grass-type attacks will render Bellossom virtually useless except for
healing. It does have SolarBeam, which it can fire off in one turn if the weather is
Sunny, so be careful of that!
After beating Erika, she'll relinquish TM19, which contains Giga Drain. Giga Drain does a
moderate amount of damage, but it restores the user's HP by 25% of that damage. She'll
also give you the Rainbow Badge, of course.
Now that you've beaten Erika, why not head on south towards Fuchsia City? You'll need to
go down there anyway, so now's a good time for it! Head on west of Celadon City to get
onto Route 16.
