AGGRON
There we go, got the part that people browsing this thread wanted to see out of the way, and now my opinion becomes lost amongst a sea of anonymity. Poetic nonsense aside, having a 6ft 11inch tall steel dinosaur, weighing in excess of 750 pounds as a traveling companion seems to suit me down to a 'T', and here are the main reasons why...
1. Intimidation factor: or Winning
without fighting.
Aggron is a heavyweight in more ways than one, and his sheer force of menace is up there with the mightiest of dragons, or the spookiest of ghosts as his entire head is clad in metal - with two protruding horns and a bear-trap like jaw - every part of him is weaponised.
Unless I knew my Pokémon quite well, and picked a ground type to reduce Aggron to mincemeat in an anticlimactic slaughter (seriously, screw ground types as an Aggron, they will make your life hell...) then I would not relish the prospect of combating such a monster, or more accurately, I would run in the complete opposite direction screaming like a ninny.
2. Big surprises in small packages: or "
Aww look at the cute little Aron, isn't he ado-OH GOD HE'S
HUGE NOW RUN!"
I've always been a fan of the huge, unsubtle leaps in evolution in Pokémon, such as Magikarp to Gyarados, Pupitar to Tyranitar etc. and Aron's rapid ascent into a god of war is certainly up there. Little do you know that the cute little critter you caught unassumingly in some dark, dusty cavern will eventually become a bipedal behemoth, and it certainly is a surprise that does not disappoint.
3. Prepared for all-comers: or a move-set divine
Now, Aggron's move-set that is earned by leveling up is powerful but limited to dealing with certain types of Pokémon, but as every good trainer knows, the right TM's turn the tide of war. The appeal of having a nightmarish dino-knight bust out a thunderbolt, aerial ace, ice beam or flamethrower is one that can't be beat for me. Now
granted, with most Pokémon you can harness the awesome potential of a TM to make a logistically wacky, but immensely powerful arsenal of multiple types, but there is just something inexplicably satisfying to me about seeing my Aggron shatter the dreams of a cocky water type opponent, with a single dose of thunder.
4. The 'it' factor: or a nonsense explanation as to how my subjective favourite is superior to yours
Perhaps the reason why I like Aggron so much, is one that I can't explain, I just do. It isn't like starting to grow in affection for a certain Pokémon after their heroics late on in a gym battle, or the unexpected slot filler in your PC pox becoming your most valuable asset (I like the Pokémon Illumise for these such reasons, not usually the type I'd like but was so useful in Pokémon X to me, she became a firm favourite) instead, it is just the simple fact that much like people click or do not click with other people, certain Pokémon just click with certain trainers.
Wait, you made it to the end of this list? I'm impressed honestly, oh wait... you didn't just scroll by to leave your comment and this is the only part you caught did you?
Sigh, my genius is wasted once again.
