Finally! This took for ever. Grinding just isn't fun to do on four hours of sleep after a big night out. This update was kind of fun to do though, because I did the Norman fight with a friend. We shared the joys... and the pain, but I'll let you read about that.
OP
Why King Serperior is on my list
So STRONG had defeated Flannery, and May had just given us (Inspector Gadget's Go) Go-Goggles. So we decided to hit up the desert for some grinding. First thing I noticed was the tower was missing. I asked an NPC, he said that it dissapears for some reason sometimes. So I consulted my new favourite in-game resource, Bulbapedia, which says that it appears and vanished every time I left the route. So naturally I abused this knowledge. However, I decided not to grab a fossil, because these were the strongest wild Pokemon that I could battle, and the tower was out of the sand, so I wanted to keep my grinding spot for later.
Upon realising that there is like nothing to do between Flannery and Norman, I went back to Petlburg. Seriously, Game Freak, in the inevitable remakes, I'd put the Team Magma/Aqua, Mt. Chimney thing here. Gives you something to do between badges, you know?
Anyway, I was clearing out the gym, and freaking out that Random was being OHKO'd by all the trainer poke's. For you see, I planned to rave Random solo Norman so I could evolve him. Some funny stuff happened with the gym trainers and Metronome. First off, there was the accuracy room (the trainer uses never miss moves) and I get Kinesis (lowers accuracy). Second was a gym trainer's Focus Punching Spinda:
Spinda is tightening it's focus.
Random used Metronome
Me: Please be a damaging move
Random used Fury Swipes
Me: :D
Random's attack missed.
Spinda used focus Punch
But Random survived anyway, so I guess it didn't really matter.
So insert one 'Eye of the Tiger' training (read: grinding) montage for Random (man, I sure do miss Audino and Lucky Egg) and we were ready to face Norman.
This took about eight attempts. The funniest fail ended up with a Linoone sweep. That thing has freaking Belly Drum.
But on my successful attempt. I used a lot of healing items and X Defends. Oh, and for the Pokemon I had to beat using only Metronome that was Linoone. Let me share this amazing story with you.
Linoone used Belly Drum.
Random used Metronome
Random used Flame Wheel
Linoone is burned.
And basically because every attack still destroyed Random, I had to just keep spamming healing items on him. Which was annoying because Norman used TWO hyper potions on the damn thing!
And then there was Slaking, basically it was just heal/x defend when he attacked and attack when he loafed around uninteresting really. And when that Slaking went down, I watched Random's experience bar shoot up... and stop just short of leveling up, and evolving. Next time I guess.
The Team

RNG/Marshtomp (M) @Quick Claw
Lv.26
Nature: Quiet
Foresight
Growl
Mud Sport
Water Gun
2/3 gym's solo'd.
I picked up the TM for Sandstorm - a rock-type move - and thought I was finally going to be able to fulfill his 'all different types, only one damage move' requirement, but alas no. He's going to get Surf in a second to replace Water Gun though. So I'm pretty happy with that.

Gorgeous/Kirlia (M)
Lv.26
Nature: Quiet
Psychic
Confusion
Double Team
Calm Mind
I think Gorgeous serves as cannon fodder at some point in this part. That's about it I guess.

Boombox/Loudred (F) @Silk Scarf
Lv.26
Nature: Quiet
Pound
Uproar
Supersonic
Howl
28/50 moves used.
Again, I don't think he's done anything... like ever. I think he's used 5 attacks since the last update.

Random/Makuhita (F) @Persim Berry
Lv.32
Nature: Quiet
Metronome
Vital Throw
Smellingsalt
Arm Thrust
Present, I take back everything I've ever said about you and RNG. King Serperior, I hate you. That is all.

Booster/Torkoal (M)
Lv.27
Nature: Quiet
Ember
Body Slam
Curse
Protect
Did I ever mention that I love Booster? Because I'm pretty sure everyone needs to know about how much I absolutely love this guy. Thanks, Jimera0.

STRONG/Spinda (F)
Lv.30
Nature: Mild
Rock Smash
Psybeam
Hypnosis
Strength
Yup. Didn't do anything. The end.
Remember, whatever I may say. I don't really hate you guys, you just make my life hell, and that's why I love you... because I'm a masochist.
