Hmm. This thread seems the closest to what I want to post, so I guess I'll put it here. If this shouldn't go here, let me know what fits it better.
Here are my favorite (no "least faves") of each type of each generation.
Type Gen I/II/III/IV/V
Normal Eevee (so cute!)/Girafarig (odd but neat)/Zangoose (love the red stripe pattern)/Porygon-Z (nice stats and design, computer-dwelling Pokemon is cool concept).
Fire Ninetales (one of my overall faves, cool design, cool Dex entry)/Entei (again pretty cool design)/Blaziken (nice look and loved using it in Hoenn)/Infernape (not much to pick from, but still it was fun to use once I tried one in Sinnoh)/Tie between Victini and Reshiram (design and backstory).
Water tie between Wartortle and Vaporeon (both look great)/Suicune (Suicune, need I say more?)/Kyogre (powerful and good design)/Manaphy (one of the coolest waters, and the only hatch-able legend)/probably Keldeo, followed by Frillish (K-neat design and backstory, F-cool type and design)
Electric Zapdos (great type and looks)/Raikou (hmm, seems I have a thing for the Johto trio)/Manetric (not much to pick from, but of the options available . . .)/Luxray (its a lion that can see through walls)/Zebstrika or Zekrom (design for the zebra, "ideals" concept for Zekrom)
Grass Venusaur (looks the best of all 1st gen Grass)/Bayleef (best of its line, appearance wise, and was fun to use in Gold)/Tropius (neat concept)/Leafeon (pretty and hey, I like Eeveelutions)/Serperior (Best. Grass. Ever.)
Ice Articuno (pretty and cool)/Sneasel (one of my faves of the 2nd gen)/Snorunt (this guys pretty funny looking . . .)/Froslass (and evolves into something awesome)/Cryogonal (so odd it's great)
Fighting Poliwrath (water/fighting is a good mix)/Hitmontop (upside-down!)/Breloom (again, design and I liked using one in Hoenn)/Lucario (beats the 4th gen competition, and is cool in it's own right)
Poison Weezing (only weak to Psychic)/Crobat (fast, four-winged bat)/Seviper (colors are awesome)/Drapion (kicked butt in Sinnoh)/Trubbish (so cute and funny. Odd that it's evolved form is one of my least favorites ever).
Ground Sandslash (love that design the most of all Grounds)/Gligar (Ground/Flying is such an odd combo)/Flygon (desert dragon, amazing design, levitates)/Torterra (come on, it's awesome)/probably Golurk (haven't used one yet, but I like the design)
Flying Aerodactyl (cool looks)/Murkrow (one of my overall favorite birds)/Altaria (so fluffy)/tie between Honchkrow and Chatot (power versus design)/Archeops (awesome colors, too bad about the ability, though)
Psychic Mew (my first favorite ever, still holds a special place in my heart-just look at my username)/Espeon (beating out Xatu for it's cool face fur)/Metagross (pure awesomeness. The thing's got four brains!)/Azelf (best design of the Lake trio)/Musharna (Dream Smoke!)
Bug Syther (the original ninja bug)/Ariados (color scheme)/Ninjask and Armaldo tie (speedy ninja versus fossil bug)/Yanmega (just cool all around)/tie between Volcarona and Galvantula (so . . . awesome . . .)
Rock Omastar (my first fossil back in Red, and so cool looking, too)/Tyranitar (strong, snadstream, what more do you want?)/tie between Lunatone and Solrock (like the concept)/Rampardos (mainly because it was the best of the 4th gen competition)/Gigalith (love the design, love the shiny even though I don't have one, just cool)
Ghost Haunter (sweet design, best of its line looks-wise)/Misdreavus (yeah, there were a lot of Ghosts in gen II . . . seriously though, it is pretty cool)/Sableye (fun fact, it has a Ruby, Sapphire, and Emerald on it's back)/Rotom (ghost that can infiltrate electronic devices? Yes, please!)/Litwick (like the whole line, but Litwick's the coolest looking of the three)
Dragon Dragonair (pretty, and can change the weather according to the Dex)/Kingdra (see: Misdreavus)/Latias (great type, great stats, great design. Latios wins when comparing shinys, though)/probably Giratina (two formes, great backstory)/Reshiram and Zekrom tie, though Zweilous isn't far behind (R@ms backstory, Zwei because it's two heads are always fighting!)
Dark (none in first gen)/Umbreon (need I say more?)/ABSOL! (Ranks really high up there among my faves)/Darkrai (cool ability, backstory, and design)/Zoroark (Illusions? Yes. Fox? Yes.)
Steel Magneton (for lack of competition)/Skarmory (looks cool and has blades for wings)/Mawile (with Metagross as a close second, but Mawile's cute face just barely wins out)/Dialga (design is wonderful!)/Exadrill (so cool)
Like I said, I'm not really sure if this belongs here, but the title is "Favorite of each type" and that seemed to fit better than the other Favorite Pokemon sticky . . . feel free to move this if it doesn't fit here.
