4th Gen Favourite Pokémon.... :>

Infernape and Staraptor man! They are pretty cooooolll and i love them! first two pokemon whom i used the most playing Diamond First Time!

Staraptor, an early Normal/Flying type that's actually good. I suppose Swellow isn't bad by any means, but a decent Fighting move to hit Rock and Steels with puts Staraptor way ahead of the others.

Gastrodon, mainly because of how good it is for online battles. Good type combo, Good HP and defensive stats, immunity to Water/Electric and Toxic/Recover makes it really hard to bring down.

Weavile is my favourite gen 4 Pokemon. He's the fastest Dark-type in the game, has access to good moves like Swords Dance, Night Slash and Ice Punch and tbh it's one of the coolest-looking Pokemon of all time. If it wasn't for my Weavile, it would have been extremely hard for me to get rid of Cynthia's stupid garchomp (I'm not capping it because it was uber at the time I beat her). Then I found out Weavile was excellent competitively as well(and underrated), with access to Pursuit, Low Kick and Ice Shard to give it a niche as a trapper and dragon slayer all in one (that was back in Gen 5). Gen 6 gave Weavile Icicle Crash and Knock Off, which finally means Weavile is no longer as predictable as it was, as well as giving it stronger STAB moves.

My favorites are the Luxray and Magmortar.

I like Magmortar because he looks like this big tank who just douses everything in lava.
Luxray because its an electric cat, an opposite to one of my favorite Pokemon, Manetric.

Weavile or Monferno, I think. Weavile is the evo of one of my favorite pokemon, looks cool and has an interesting dual typing. Monferno is probably the fire/fighter starter I like most, together with Infernape (and Blaziken), because of it's cute monkey looks and also fire types usually interest me in general.

Mothim, Cherrim, Pachirisu, Ambipom, Honchkrow, Glaceon, Leafeon, and Shaymin. Just can't say no to these cuties. :)

Cherrim is especially cute but I so wish it didn't require sunny weather for it to open up the flower. Weavile is cool too but I'm more for cute than anything! I have a soft spot for the smaller Pokemon so these really stick out with the occasional cool 'mon that catches my eye (Honchrow, Ambipom).

I love arceus :) and glaceon

My favourite Gen 4 Pokemon are Infernape, Empoleon, Lucario, Garchomp, Staraptor, Luxray, Roserade, Weavile, Magnezone, Tangrowth, Togekiss, Gliscor, Gallade, Froslass, Drapion, and Heatran.

I like Luxray, it has a decent design and a good moveset. It also is avalible in at start of the game so its convenient. Every time i start a new save i catch a shinx just for those reasons

So, so many... Gen IV ironically introduced a lot of Pokemon that became my favourites of their respective types.

If I had to pick just one, I'd have to go with Floatzel. It's design is just amazing- it really looks streamlined and swift, and its stats match that very well. I always tend to catch a Buizel when I'm out by the Valley Windworks, just for that~

A few others I really like are Rampardos, Roserade, Luxray and Skuntank.

Toxicroak and Drapion are my two favorite things from GenIV. It was a good time to be a poison-type fan when those two were introduced. ^_^

I would have to go with Dialga and Lucario were my favorites out of the fourth generation.

Empoleon. He is my favorite pokemon ever.

Gotta go with 4th Gens Pseudo legendary Garchomp. I love powerful Pokemon.

... do I really need to say more? :D

Absolutely Garchomp! Hands down.

Luxray for sure! He is my favorite of all time!

Floatzel is not just my favorite Gen 4 Pokemon, but my all-time favorite. It has a really cool design and a lot of good moves and stats. It also reminds me a lot of myself in a way. Every time I play a game and I encounter a Buizel, I will always catch it, and I usually don't use other water types (even if my starter was a water type) unless I'm playing a game before Gen 4 or Floatzel isn't available.

I also like Lucario probably just as much as other people do, but I like Floatzel more myself.
