Grass Pokémon weren't exactly hard Pokémon to fight.  In fact, in my opinion, they were weak.  That was why I didn't have a Grass-type Pokémon on my team.
Fire Pokémon were great.  Plus, one needed a Pokémon that can Fly.  Therefore, I had Ho-oh.
Psychic Pokémon were almost essential.  The Flying part of Lugia makes him weak, but it's a small price to pay for the strongest Pokémon in the world (besides maybe Crystal's Mew).
Water Pokémon were also a necessity.  Feraligatr just happened to be strong enough and have diverse enough attacks to make my team.  A Lapras could easily replace him, though Lapras cannot learn Crunch and Earthquake.
If one did not have an Electric Pokémon, one was in some deep trouble.  Electric Pokémon were some of the greatest Pokémon to have around.  Of course I had to have Ampharos.  Besides that, he's a very powerful Pokémon.
Tyranitar was a very, very Pokémon, and was Dark and Rock.  Though neither type was essential, he made a great team-mate.
Heracross was just a wasted spot, really.  Bug and Fighting Pokémon are almost worthless, since they are weak to several types, and not too strong against many types.  Still Heracross was a great Pokémon to have.  She could have been replaced, but I liked her.  She was a good Pokémon.
That was my team.  A very formidable team, but it could be tweaked.  I wasn't sure how, but it could.  Kamon said that it wasn't the Pokémon I used, it was how I used them.  I think he was full of crap.  Lugia could beat any Pokémon he wanted.
'Because,' Kamon said, 'you have faith in your Lugia.  Let's take my former rival, Jet, for instance.  He had no faith in his Pokémon, and treated them as mere tools.  He failed at every attempt to beat me.  Now look where he is.'
'Um,' I said, 'where is he?'
'Jail,' Kamon replied.
'Ah.'
We continued on to the next island: Kumquat Island.  We healed our Pokémon and then walked into the gym.
This gym wasn't like a normal gym; this gym was made out of grass and wood.  Like an old-fashioned island hut.
The leader was a girl named Ashley.  When I was about to challenge her, Kamon stepped in my way.  'I wish to battle you first,' he said.  I scowled at him.  'For once, I want to battle first.'
I sighed in defeat.  'All right,' I replied.
'I will tell you,' Ashley said to Kamon.  'I am no pushover.  My older brother is the Champion of the Orange League.'  I thought for a moment, and then asked how old she was.  '13.'
'Hm...' I said.  Then, I thought, I wonder who her older brother is...
Kamon sent out his first Pokémon.  'Delibird, go!'  He should have saved Delibird for later, but hey, it's his battle.
'Then I'll choose Beedrill!  Go!' Ashley yelled.  'Use your Pin Missile!'  Beedrill fired several needles at Delibird, doing mediocre damage.
'Delibird, Fly!' Kamon commanded.  Delibird flew into the air, and then slammed into Beedrill.  Ashley's Pokémon retaliated with Hyper Beam, doing an incredible amount of damage.  Delibird came back with a Wing Attack-critical hit-knocking him out.  'Nice work, Delibird!' Kamon exclaimed.
'Beedrill, come back, and go!  Victreebel!  Acid, now!' Ashley said.  Delibird suffered the attack, and fainted.
'Return,' Kamon said.  'Entei, come out and use Fire Blast!'  The legendary flame Pokémon unleashed the powerful Fire-type attack, nearly knocking Victreebel out.
'Victreebel, Body Slam!'  Victreebel went to slam itself on top of top of Entei, but missed.  Kamon didn't miss an opportunity to attack, so he commanded Entei to use Flamethrower, knocking Victreebel out.  'You rest, Victreebel.  I choose you, next!  As my last Pokémon, I choose Bellossom!'  Ashley sent out her final Grass-type Pokémon, and told her to use Sleep Powder.  The attack failed.
'Entei, another Fire Blast!' Kamon cried.  Flames poured from Entei's mouth and struck Bellossom.
'Bellossom, Sleep Powder!' Ashley said.  This time, the attack succeeded.  Entei drifted off into a deep slumber.  'Good job, Bellossom.  Now attack with Giga Drain!'  Bellossom sucked health from Entei while he slept.  Ashley then told her Pokémon to use Hyper Beam, taking away even more health.
Finally, Entei woke up and used Flamethrower, but missed.  Bellossom knocked the shiny legendary Pokémon out with another Hyper Beam.
'Dang,' Kamon said.  'Go Typhlosion!  Fire Punch!'  Typhlosion upper-cut Bellossom, knocking her out.
'Aww...return.  Well, you win.  Here's your badge,' Ashley said.  Kamon received his badge, and I stepped up.
'All right, it's my turn,' I said.  'Go, Heracross!'
'Scyther, come out and use Wing Attack!' said Ashley.  The Bug Pokémon slammed into Heracross, doing an unusually high amount of damage.
'Heracross, return.  Tyranitar, go!  Rock Slide!'  Rocks pummeled Scyther.  Before Ashley's Pokémon could come back with another attack, Tyranitar used Rock Slide again, knocking out Scyther.
'I'll choose Meganium next,' said Ashley.  'Use Solarbeam!'  While Meganium gathered energy, Tyranitar used Flamethrower.  Meganium then fired the gold Solarbeam, but Tyranitar caught it in her hands.
Tyranitar was getting pushed backwards by the beam, but she wasn't giving up.  Suddenly, Meganium used another Solarbeam, overwhelming Tyranitar.  She rose from the ground, however, and then used Fire Blast.  The attack missed.
'Meganium, finish off Tyranitar with Giga Drain!'  the enemy Meganium sucked the remaining health from Tyranitar.  I recalled my Pokémon, and then sent out Heracross again.
'Heracross, Mega Horn,' I instructed.  Heracross charged at Meganium, buried her horn in his side, and then flung him across the room. 'Great job,' I said.
'Meganium, Body Slam!'
'Detect!'  Heracross blocked the attack and then proceeded in using another Mega Horn, critical hit, knocking out Meganium.
'As my last Pokémon, I'll use Ivysaur!  Use Body Slam!' Ashley yelled.  This time, the attack succeeded, paralyzing Heracross.  I called her back again.
'Feraligatr, go!  Use Blizzard!' I commanded.  Snow and ice battered Ivysaur, but the Pokémon was not yet knocked out.
'Ivysaur, Razor Leaf!'  Small razor-sharp leaves sliced away at Feraligatr, but he came back with Ice Beam, knocking out Ivysaur.  I had won.  Again.
'Good job,' I said, recalling my Pokémon.  Ashley did likewise.  She handed me the badge, and Kamon and I moved on to Pulp Island.
