1st Gen What's your favourite legendary in RGBY?

There are only 5 of them so it's not easy to decide. Legendary birds aren't my thing and I don't really like them. And if I had to decide between mew and mewtwo, I'd definetly choose second one. Its stats are much better.

Definitely Zapdos for me. :D

Articuno for me. I'd always make sure that this was the one legendary I use on my team as it was just so useful especially against Lance.

Zapdos, with it's great 125 Special and 100 Speed and good Electric/Flying stat. Zapdos's main flaw is that it's ugly as hell. I don't like the other four, though I love Moltres's design. Articuno is bland and becomes useless in later generations, while Mewtwo is: 1) overrated; 2) overpowered; 3) not very good-looking; 4) Uber. Mew is too hard to obtain and has a really bad Green sprite.

All of them lol

I liked my Charizard L76 more tbh

but Mewtwo is cool and the strongest pokemon to catch so if it comes to a decision I'd say him

My favorite gen 1 legendary is Mewtwo. It's an amazing Pokémon in gen 1, and the other legends don't really compare in that regard. Plus, I've never been that fond of flying Pokémon (like Articuno, Zapdos, and Moltres) anyway--while a few are nice, there are far too many of them in my opinion, and they have too many common weaknesses.

.

Of course it has to be Articuno. Great Pokemon. Wrecked Lance, I remember the first time i looked through the binoculars before fuchsia city..? Not sure of the correct spelling.
& seen "" in pokemon yellow i instantly fell in love. I remember thinking.. "now who the hell is that Pokemon?!"
To this day, Articuno is still one of my favourite legendaries.

NOTE: IF YOU CAUGHT MEW FOR OTHER REASONS THAN COMPLETING THE POKEDEX AFTER FINISHING THE GAME, YOUR A CHEATER.

( I liked everyones posts agreeing on the majestic ice bird also ;) )

my favourete is articuno. He has good special and has ice beam!

I don't know how you can say no to Mewtwo. Just so overpowered and it didn't look stupid, like most of the birds. The birds also had terrible movepools when you caught them, so that took the fun out of them for me.

articuno and mew and giant dragonite

Would Arcanine count? After all, its original Pokédex entry stated that it was a legendary Pokémon. Haha. ^^" If not, then my favorite first generation legendary is Zapdos, because it's a great Pokémon to battle with. I also like Articuno, because its design is very beautiful.

If we're only talking games, it's probably Mewtwo or Zapdos or Suicune. Even though I like the designs of Moltres and Articuno (and all the Johto legendaries for that matter) better, Zapdos is the only legendary bird I remember really using in a game. And Mewtwo was so cool and strong that I just had to use it after E4 :p Not that there was much to do then, of course. But still. Suicune is the only legendary beast I remember using at some point. And it was good enough as a water type, even though I think I switched it out after a while again haha. But that's because I've always preferred using non-legendaries.

My favourite legendary in the 1st generation is Articuno, hands down. What a great design

Eeeeveeeee! I know she's overrated but she's just SO CUTE!

Articuno, always! When I'm playing RBY I always catch Articuno after I obtain the Master Ball.

Zapdos, he just looks amazing :3

Mew because it's so unique and I honestly think it's the cutest thing ever. I know it can't normally be found in R/B/Y but I think it still counts since there's data for it. My second favourite would be Articuno cuz it looks so graceful and elegant and Zapdos would be my third favourite. I have no opinion on Moltres or Mewtwo tho.

1. Articuno
2. Mew
3. Mewtwo
4. Zapdos
5. Moltres

I always loved Articuno's design and move pool. Moltres, on the other hand, I always thought looked terrible. Never really had an opinion on Zapdos, too.

It was Zapdos for me, and it was the first legendary I caught in a Pok'emon game (Blue). Remained as the main "shocker" of my team until I'd stopped playing Blue.
