Pokemon Gold, Silver and Crystal Elite Four: Will

I'm going a little off from what I normally do, but since I've got a friend in need I'm doing an Elite Four bio for Will, the first member of the Elite four in GSC. His specialty is Psychic type.

Will's Pokemon are as follows:

Xatu:
Lv. 40
Types: Flying and Psychic
Item: None
Attacks: Quick Attack, Future Sight, Psychic, Confuse Ray

Exeggutor:
Lv. 41
Types: Grass and Psychic
Item: None
Attacks: Reflect, Egg Bomb, Psychic, Leech Seed

Slowbro:
Lv. 41
Types: Water and Psychic
Item: None
Attacks: Amnesia, Curse, Psychic, Body Slam

Jynx:
Lv. 41
Types: Ice and Psychic
Item: None
Attacks: Ice Punch, Double Slap, Psychic, Lovely Kiss

Xatu:
Lv. 42
Types: Flying and Psychic
Item: None
Attacks: Quick Attack, Future Sight, Psychic, Confuse Ray


To fight this member of the Elite Four, I would suggest a strong Ghost type like a Haunter or Gengar, or Dark type, which by this point the only one you can get is Umbreon. Make sure that your Pokemon are at least lv. 45 before you enter the E4 fight!

Pokemon Diamond and Pearl Elite Four: Aaron

Aaron is the first of the Elite Four that you need to fight in Pokemon Diamond and Pokemon Pearl. His specialty is bug-types and he has one Pokemon that is not a bug type.

Aaron's Pokemon are as follows:

Dustox:
Lv. 54
Types: Bug and Poison
Item: Sitrus Berry
Attacks: Bug Buzz, Toxic, Light Screen, Double Team
Ability: Shield Dust

Beautifly:
Lv. 53
Types: Bug and Flying
Item: None
Attacks: Bug Buzz, Psychic, Energy Ball, Shadow Ball
Ability: Swarm

Heracross:
Lv. 54
Types: Bug and Fighting
Item: None
Attacks: Megahorn, Close Combat, Stone Edge, Night Slash
Ability: Swarm

Vespiquen:
Lv. 54
Types: Bug and Flying
Item: None
Attacks: Attack Order, Defend Order, Heal Order, Power Gem
Ability: Pressure

Drapion:
Lv. 57
Types: Dark and Poison
Item: Sitrus Berry
Attacks: Cross Poison, X-Scissor, Aerial Ace, Ice Fang
Ability: Battle Armor

To defeat this member of the Elite Four having a level 55+ fire Pokemon would be a good idea to have. With your fire type you should be able to beat the first four Pokemon pretty easily, and four Drapion, you should get a similarly leveled fighting type. I would recommend Lucario because it has a steel type too, and Drapion's Cross Poison attack will be made ineffective and the other moves will only do half as much damage.
