My Legendaries
I have collected a fair amount of Legendary and Mythical Pokemon throughout the years! I once aimed to get all of them, but missed out on a few event Pokemon... oh well. Here you can see my collection of legendary Pokemon, as well as which ones I'm missing.
Generation I
Articuno, Zapdos, Moltres
I first caught these guys in Yellow, where I used Moltres and Articuno to beat the League. Then I transferred them from LeafGreen all the way to Pokemon Y, where they are just relaxing in a box. I appear to have caught another Zapdos in Pokemon Y?

Mewtwo
Facing off against Mewtwo in Yellow was a high octane experience. Getting this guy down to a sliver of red and then tossing Ultra Balls at him... but apparently getting that slice of HP down was unnecessary.

Mew
A friend of mine lent me his copy of Pokemon Blue and never came back to pick it up before moving away for good. Well, you can't do the Mew Glitch on Yellow, so I tried it out on Blue. I knew it worked because everyone said it would, and yet I felt my heart pound as I saw Mew appear on screen. The Mew from Pokemon Y was received in an event, but I don't remember much about it. It goes to show the difference between having something gifted to you and doing something a little off-menu to get what you want...

Generation II
Raikou, Entei, Suicune
I caught a Suicune in my very first copy of Pokemon Crystal using a Master Ball. I felt a sense of anticipation walking through the tower, that path up to where Suicune lived, and I faced off against it... I went straight to the menu and tossed my Master Ball at it. It worked - of course it did. I told my friend about it and he told me it was a silly thing to do, and I should have saved it for a difficult Pokemon like one of the wandering beasts. I nearly cried hearing that! I don't have that save anymore, and Suicune doesn't appear in my saved Pokemon on Pokemon Stadium 2. Master Ball Suicune is nothing but a memory.
The Shiny Beasts are from a Gamestop event. Fun, huh? I certainly wouldn't be bothered to try for Shiny Beasts in the game.

Lugia, Ho-Oh
I'm pretty sure I never got Ho-oh in my original copy of Pokemon Crystal because you needed to get all three Beasts. And I did not do that! There is a chance I got Lugia, which has more lenient requirements, but I cannot remember well. In HeartGold, both legendaries are pretty accessible.

Celebi
Celebi was a real fixation for me as a kid. Mew could be gotten through the Mew Glitch, and I had the Jirachi disk, but there wasn't a legitimate way for an American to get Celebi for a while. My friend had a Gameshark and sharked me a Celebi. I had a chance afterwards to get a real Celebi at the "Pokemon Across America" event for the tenth anniversary of Pokemon. This Pokemon is very precious to me in a lot of ways, so precious that I didn't move it forward like I did many other of my Pokemon. I moved forward my Rayquaza and other legendaries, but that Celebi has lived on that Emerald file since.
I since got two more event Celebis. Funny that a Pokemon that once seemed so rare and unobtained is now overrepresented in my collection.

Generation III
Regirock, Regice, Registeel
The mysterious ways in which you get these Pokemon captivated me a kid. The Braille, the Relicanth, the Wailord, the surfing currents! And their faceless inorganic forms! I like all of them, but Regice might be my favorite. I probably wouldn't have the patience to go through it all today, but I'm happy I had that experience back then. Perched over my Ruby/Sapphire guide, making sure I was surfing the current currents... hunting for Relicanth... sharing the secrets with my friend... these form many of my happy summer memories.

While I did try to hunt the legendary Beasts and the emotion/willpower/knowledge spirits of D/P/Pl, I don't recall hunting for the Latis. I'm still pretty fond of them and their portrayal in the movies.

Kyogre, Groudon, Rayquaza
Here's a random memory for you - a classmate of mine insisted that "Kyogre" was pronounced "KEE-oh-grey." I, of course, insisted on "kai-OH-ger." Kyogre and Groudon are story creatures, and so not very memorable to me, but Rayquaza... that mach bike section killed me. And Rayquaza was pretty high-leveled, so you had to come prepared to capture it. I was quite proud to finally capture it.

Jirachi
I have two of the Pokemon Colosseum Bonus Disks. I don't know why. It doesn't work twice. And it doesn't work on Emerald! I had Ruby and Sapphire so you may wonder why I don't have two Jirachi, and that's a good question. Perhaps I generated one for a friend which I've since traded away. In any case, I have Jirachi here.

Deoxys
Deoxys is another memorable Pokemon for me, an inaccessible mystery on the level of Celebi. I knew from Serebii that there was an event that could get it for you, but it was not available in America. I turned to hacking. I'm pretty sure the first Pokemon my friend hacked for me was this Deoxys, which had a weird OT. I'm not sure how he fixed the OT later on Celebii.... in any case, this Deoxys was able to hop from gen 3 to 4 to 5, but no further. I was able to get a Deoxys through a special event in Gen VI, so perhaps it all worked out.

Dialga, Palkia, Giratina
These are story Pokemon, and so not very notable... well, except for one thing. I didn't buy Pokemon Black 2 or White 2 because I had this fixation on getting Palkia and I couldn't decide which to get. It was the first time I did not buy the 'third' game for a generation. It took until HeartGold for me to get Palkia.

Manaphy, Phione
I wanted to get the Pokemon Ranger game when I was younger to get the Manaphy egg. I've been told nowadays a lot of the Pokemon Ranger games have had their Manaphy eggs claimed and so there is no point in buying them - you would need an external tool to erase the flag. I seem to have gotten this Manaphy through some sort of event, and I'm happy I got to get one - but I wish I could have tried for the Pokemon Ranger one as well!

Darkrai
What memories of this one - I went to an event in real life to get this event to capture Darkrai. I had saved before starting the event so I could experience it over and over again. It involved having a nightmare in a hotel. I played the scene over many times and even wrote it down to report for a very old website of mine. I couldn't bear to capture Darkrai for a while, as it would end the scene. But eventually I went through with it, figuring that I got the event for a reason.

Shaymin
I missed Shaymin when the event came out and I regretted it so much! A friend of mine got it and I wanted to trade with him so I would at least have it in my Pokedex. I loved the floral theme surrounding Shaymin and both its hedgehog and adventure dog forms. The event eventually made it accessibel to me.

Remember how I told you I missed the Genesect event? I missed these two, and it really brought me down. It shouldn't have, being unimportant in the grand scheme of things, but I really wanted to get them all, you know? And I still am missing these! Missing three made me stop my journey. It was a little silly, but it was an important goal to me at the time.
Generation VI
Xerneas, Yveltal, Zygarde
I find it funny that I have Pokemon Y and so have Yveltal, and yet I have two shiny Xerneas because I had two gen VI games. And I have four Zygarde... who needs four of them? I have as many Celebi as I do Zygarde, and one of those Celebi was hacked! But you know, there's nothing wrong with Zygarde, and I like the snake and dog formes.

There were just so many here that I kind of felt overwhelmed. It's not as bad as Unova but seeing a long list of legendaries and mythicals gives me a touch of anxiety.
I will say that I experienced the Pokemon Go event with Meltan and it was very fun! I didn't actually catch it - it was the one where "Meltan" was revealed to be Ditto - but it was great fun roaming around catching these fake Meltan. Unfortunately I didn't catch enough Ditto to progress to the next stage of the research project. 'Tis a real shame because I love Meltan!
