Favorite Legendary

[Calvin Cool]

Rayquaza, Cobalion, Latios.

 

[SerenaForTheWin]

kyogre, cresselia, articuno, palkia were my top favorites

 

[Srignan]

My favorite 3rd gen and all time favorite is Latios.

 

[egroendyk]

I love each legendary in Gen III, but... ohh, man. I think Latios wins. Almost jumped on the Deoxys bandwagon, but the Latios bandwagon was callin' my name just a lil louder. lol

 

[Charoshi]

For those introduced in Gen 3 it's Regice.

Overall it's Lugia by far.

 

[Ben10jon3]

Rayquaza is just too cool
Catch him with a master ball and it will look cool when you enter him in the battle!
(Also, if you use the master ball on rayquaza you will have a hard time catching latios/latias)
(I caught latias with a poke ball)

 

[Saturnidae]

Kyogre. It's just so awesoume! like some sort of mososaur, or a prehistoric whale.

 

[Megahound]

Rayquaza is.

 

[FantasticAltaria]

Mine would probably be Kyogre because he looks pretty awesome and I also like water types.

 

[Timmyzzz]

Rayquaza's my favorite, but it's quite OP. My next favorite would be Latios xP

 

[X-Caliber]

Was Lugia and this year became Xerneas

 

[Volcer]

Latios is one of my favourites, and favourite Hoenn legendary.

 

[Chalis]

Lugia, but my favorite in the third gen is Groudon. It was the first i ever got ( I only had ruby.)

 

[KamenAeons]

A tie between Suicune, Latios and Rayquaza.

 

[Slowy]

If I were to do favorites, I'd go with my favorite from years ago; that'd be Rayquaza, as it not only had intriguing stats and moves, but something about its abilities made me feel excited. That was especially the case in Emerald Version; not only did I get to capture it with a Master Ball before the 8th gym, it was at level 70 to boot! I knew it was going to be amazing on the team, but also took care to have a good team if not better in general so as to get to and beat the Elite Four and Champion.

 

[Angello]

Rayquaza, it's really powerful.

 

[Ruas]

Rayquaza definitely. I still remember the excitement when I first saw it's cut-scene!

 

[~Emolga~]

Jirachi, Mew, Latias and Ho-oh

(But in gen 3 Jirachi is my fav but above are others i like as well.)

 

[Archangel Azazel]

Jirachi and Kyogre.

Jirachi is the cutest small legend and I love its typing.
Kyogre... well I like the color blue and this Pokemon is pretty intimidating looking its just... amazing *^*

 

[Steampunk]

I'd have to say Latias. Seeing as it was the roaming Pokemon of my Sapphire, it seemed like such a challenge and it was just so cool to me when I finally caught it.
