Bug: X-Scissor (Solid bug type attack that lots can learn, helped to round out mah boy Sandslash)
Dark: Night Slash (Awesome move, high crit ratio, my Sniper Drapion made excellent use of it)
Dragon: Outrage (O, the power)
Electric: Thunderbolt (The staple electric move, can be learned by many, can't go wrong)
Fighting: Brick Break (It's my go-to solid fighting type choice)
Flying: Air Slash (Solid move with a flinch chance, I like it)
Ghost: Shadow Claw (Solid ghost attack, also helped round out my beloved Sandslash)
Grass: Petal Dance (It's the grass version of Outrage. Helped immensly in the mono-grass E4 challenge I did for the medal just recently)
Ground: Earthquake (The ground type move)
Ice: Ice Beam (Can't have Thunderbolt on the list and not Ice Beam)
Normal: Swords Dance (Great boost for any physical attacker. Very useful)
Poison: Sludge Bomb (It's the poison version of the move Psychic)
Psychic: Psychic (This is the number one staple move I teach any special attacker that can learn it. Maybe Gen 1 biased me towards it but I love it.)
Rock: Rockslide (Classic move, multiple targets.)
Steel: Gyro Ball (Mixed with Curse on my Platinum version Steelix, this move is just great.)
Water: Surf (Solid staple water type useful in battle and out, can't go wrong.)

 

Bug: Signal Beam; pretty and a solid move~
Dark: Dark Pulse; Just a very nice and mysterious move I love to always have somewhere on my team.
Dragon: Draco Meteor; Looove the animation, and even though its accuracy isn't perfect, I still really like it. Dragon Rush is cray too.
Electric: Thunderbolt; High power, perfect accuracy, change of paralyzing. Such a great move! I also love Discharge but it gets in the way in double battles.
Fighting: Aura Sphere; I adore this move! I typically don't like fighting types, but Aura Sphere is more pretty than physical.
Flying: Brave Bird; Bahh I don't know why I like this attack so much, I usually don't like those super powerful with drawbacks moves, but I've always liked Brave Bird.
Ghost: Shadow Ball; Again, a solid move with high power and perfect accuracy.
Grass: Petal Dance; I love a lot of Grass moves, and I almost said Energy Ball, but Petal Dance just makes me think of a Pokémon dancing all pretty like and I've always thought this move was awesome.
Ground: Earthquake; Ah, how can I not say EQ? It's arguably one of the best moves in the entire game. It's flawless, except for hitting your teammates in double battles. Since it feels like a given, I'll name my second favorite: Earth Power. Even though I got killed by it a lot in Explorers of Time/Sky.
Ice: Ice Beam; Obv. I also like Aurora Beam because it's pretty.
Normal: Metronome; Ahaha this is a hard one! There are so many normal type moves... If Metronome doesn't count, I also love Tri Attack. And Return for just pure power.
Poison: Toxic; Pretty much the only poison type move you'll ever see on my teams... xD
Psychic: Psychic! Amazing move, one of my favorite moves ever. I love Calm Mind as well.
Rock: Power Gem. Pokémon needs better rock moves ;P
Steel: Flash Cannon; I would love Iron Tail if it weren't for the low accuracy. I'd even take lower power for better accuracy... but for now my favorite is the out-of-the-ordinary special based one like normal ;P
Water: Scald. Not sure why, I just really love it.

YOU GUYS FORGOT MY FAVORITE TYPE ;c

Fire: Heat Wave; I don't know why. Nice memories I guess. And of course Flamethrower is amazing. I also love love LOVE Fiery Dance (you sexy beast Volcarona)

And I guess it's too early to say our favorite Fairy move... Fairy Wind and Moonblast look cool though.

 

Oh wow, how did I not notice Fire wasn't on the list?

Fire: Lava Plume (High power special attack with a cool concept and animation. Just wish more Pokémon could learn it.)

 

Fire: Blaze Kick
Ice: Ice Beam
Water: Hydro Pump
Dragon: Dragon Dance
Grass: Leech Seed
Steel: Flash Cannon
Dark: Nasty Plot
Psychic: Psycho Cut
Normal: Headbutt
Fighting: Aura Sphere
Flying: Air Slash
Electric: Thunderbolt
Ground: Earth Power
Poison: Toxic
Bug: Bug Buzz
Rock: Rock Slide
Ghost: Shadow Claw

 

U-Turn (good for momentum and stuff)
Either Crunch or Dark Pulse (I couldn't choose; Crunch has a cool animation in Colosseum and it's useful for physical Darks whereas Dark Pulse is handy for specials)
Either Draco Meteor or Outrage or Dragon Dance (Former options are powerful and DD is an awesome set up move)
Thunderbolt (standard move to use for specials)
Drain Punch (Cause healing is nice with decent power to boot; would be Hi Jump Kick but it's just eh)
Flare Blitz (Awesome move for phys. Pokes and sick animation in BW2)
Brave Bird (Cause it's awesome and deals tons of damage to boot)
Shadow Ball (I guess it's good for Ghosties)
Leech Seed (Useful move, often the opponents could switch out and it steals HP too)
Earthquake (nuff said)
Ice Beam or Ice Punch (Both good moves)
Protect (A turn for scouting/protecting/stalling is nice)
Toxic (Almost every Poke learns this and handy for dealing more damage each turn)
Psyshock (Useful against Special Walls)
Stealth Rock (Best entry hazards ever)
Iron Head (Steel type moves don't appeal to me so I picked a move where a Poke turns their head into IRON)
Surf or Scald (Decent damage and stuff; Scald's handy for a burn chance)
