Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Please vote who you think improved the most from last gen to this gen, Evolutions don't count.
Posting is only required for the " Other " option, As you should post who you pick.
However, there are also plenty of Pokemon that were utter crap before that really got improved upon.
We may not be talking about those that got evolutions, but the ones that did really stepped it up. Talking about dudes like Electivire, Weavile, Togekiss, and Tangrowth.
Feraligatr finally managed to step it up with the Physical/Special split. Though he isn't as powerful as Gyarados, he doesn't suffer from any 4X weaknesses either.
Typhlosion also managed to benefit from Choice Scarf and Choice Specs.
Hm...TTar got better...but so did 'Mence. Finally gets good physical STAB, another 50% recovery move, and DRACO METEOR. Now he's really unpredictable and his hard from both sides. TTar is slightly more predictable, but when I face a Mence, I have no idea what it's going to be: CB, Specs, DD, Mixed, some weird Wish one?
Definitely Breloom. It got a 12% recovery item. Immunity to any type of Status. Physical STAB and can counter Tyranitar/Rhyperior if it uses its EVs defensively.
Gyarados has improved, but it was already OU. Same with Tyranitar/Mence.
I voted Gyarados because of: 1) Taunt lasting longer, 2) its new moves such as Stone Edge and Ice Fang, and 3) because of Waterfall becoming physical. Sure it lost HP Flying, but the new moves it got definitely make up for it.
Let's not forget our UU Deoxys-A, Pikachu. Light Ball doubling Attack anlog with access to Volt Tackle and physical stuff is probably the best thing to happen to the yellow rat.
I'm probably going to go along with Gyara also. Having a STABed water attack in the form of Aqua Tail and Waterfall really helps, and it only lost HP Flying really.
I'm going with Gyarados because though it was technically OU in Advance (I guess, we never paid that much attention to reshaping the OU tier after the middle of 2005), it was utterly walled by Skarmory and Zapdos, two of the top five most overused pokemon throughout all of Advance. TO go from questionably OU to "Your team is 6-0ed by Gyarados if it gets a DD" says all it needs to, in my opinion. Tyranitar is a very close second though, Sand Stream is hilarious
You could have just ommitted the poll and asked us. I voted Gyarados, if only that it got good STAB and move to take down Dragons. Tyranitar comes second, with a Special Defense boost that allows it to not be killed by Suicune (who appears to have disappeared), and better STAB moves in Pursuit, Crunch and Stone Edge.
