First and foremost, lets start with the Pokémon:
Smeargle is a great all-round Pokémon, as it's the only one that learns Sketch. It will learn Sketch every 10 levels starting from level 1, meaning by level 31 it will have 4 moves. Sketch will permanently copy a move used in battle, meaning that Smeargle can learn almost any move.

Mega Charizard X
Mega Mewtwo X
Pokemon Exclusive to Version Y

At the opening sequence, press the following button combination: Up + B + X. This should prompt you for deleting your save file.
The Up + B + Select no longer works on the X/Y series at the main menu, the button combination must be done at the opening movie sequence.
You can breed almost any Pokemon with Dittos regardless of gender. Ditto can be caught in the Pokemon Village or in certain Normal-type Friend Safaris.
Alternatively, as your Greninja is female, you can breed it with a male of a different type of Pokemon, so long as the male is in the same egg group as the Froakie evolutionary line.
Froakie and its ...
Here is a picture from (what I think is) the official Pokemon X&Y Guide.
Every little thing you do in Lumiose City adds to your style. Stylishness brings all kinds of rewards, such as meeting various characters, getting discounts, and unlocking facilities and fasions.
Good luck fellow trainers :)
You have a few options for Exp farming in XY. First however, let's look at what you will need to farm Exp effectively:
Exp. Share - rewards Pokémon that did not take part in the battle with half the Exp.
Received as part of the story after the first Gym, you can't miss it. Just make sure it's turned on.
Lucky Egg(s) - A hold item that ...
StreetPass provides you with an amount of PokéMiles (PM) for each person you've met who is also playing a StreetPass enabled X or Y. PokéMiles can be traded in for items at the Lumiose City Pokémon Center. Alternatively, you can redeem them at the Pokémon Global Link website via the Game Sync feature of the PSS; the prices there are lower than in Lumiose, ...

Here is the happiness page from Bulbapedia. It has not yet been updated for XY, but the boosts from Gen V have not ...
Short answer: Yes
Long answer: It depends. Mega Evolutions arent 'better' (for the most part, I'll come back to this). They are just another way of building a Pokemon, similar to if you built a Pokemon holding a Choice Item, or Life Orb etc.
Take Gengar for example. Standard Gengar is still a powerful force to be reckoned with, and its Ability Levitate ...
You can get some from the Secret Super Training levels.
From Serebii's Guide to Super Training:
If you are using a Pokémon who has got maximum Effort Values, you will gain access to Secret Super Training. [snip] ...these games give you more than just bags for core training, they also have a chance of giving you rare items. These items range from items ...
Pokemon will be sent to the last active box (i.e. the last box that you looked at). If this box is full, Pokemon will be deposited in the next box up (e.g. if your last active box was Box 23 and it is full, Pokemon will be sent to Box 24).
Simply pick a spot and use any rod.
These actions will cause the chain to break*:
Reeling it in too late/early
No fish biting (use a pokemon with Suction Cups / Sticky Hold ability in the first party slot to reduce the chance of this)
Loading/reloading a map
Entering a building
Ending the game / switching the 3DS off
These actions will not ...
These are the Elite Four trainers that you have to defeat:
Diantha, mixed team
You need a Pokemon that can learn a Ground move for Steel and Fire types, an Electric/Grass move for Water type and Dragon/Ice move for Dragon type.
For the last slot you can choose a Fire move (...
Rollerblading is only when you use the analog stick. Moving with the D-pad switches you to walking and running (with B held down).
If you are using the Dowsing Machine, you will not use your rollerblades and can still use the analog stick to move. You can still run by holding B though.
There is always a chance that a generated pokemon will be shiny. So yes a 'starter' starter pokemon CAN be shiny with the same 1 in 8192 chance as usual. But if you want a shiny you are MUCH better off trying to get a female and breeding it later. You get the Day-care very soon after the first badge so you are no longer halfway through the game before you ...
The gender ratio for the 6th generation starters is currently unknown, but all starters so far had a ratio of 12.5% female / 87.5% male, or 1 : 7.
The gender of your Pokémon does not depend on your character's gender. Both male and female protagonists can have either male or female starters.
This specific gender ratio is used to make it more difficult in ...
Route 7, which is the path right in front of the Daycare is very long at 220 steps, straight and has no obstacles or long grass.
The Daycare is roughly in the middle, and the path from it to either end and back is long enough for eggs to have a chance of spawning (which requires at least 255 steps).
Combined with the easy access to the Daycare to get new ...
Boutiques - Every day the items in the boutiques changes. These are random changes so you have to visit them frequently to find something you might want.
Hotels - NPCs moved around to different hotels each day. But their is a lady that gives you a ribbon on different days.
Saturday - Cyllage City - Snooze Ribbon
Sunday - Courmarine City - Smile Ribbon
Nevermind, I've obviously silly at looking things up. Looks like it's called "critical catching" and that this isn't a bug or anything.
It's new since Generation 5 (and appears in Generation 6). There's a slight chance where the ball will only shake on the ground once before capture.
The Japanese trainers indicate IVs using the letter "V" and indicate each stat in the order they appear on the Summary of each Pokemon:
H = HP
A = Attack
B = Defence
C = Sp. Atk
D = Sp. Def
S = Speed
If you have a 3 perfect IV Pokemon with perfect HP, Def, and Sp. Def, you would input something like:
If you are looking for Pokemon with Hidden ...
The box your capture Pokemon goes is determined as follows:
Goes to the currently active box if it is not full.
Goes to next box if current box is full.
If next box is full too, goes to the next (applicable to any other subsequent full box).
Where an 'active box' is defined as the last box you see when you log off your PC.
If you want the Pokemon you ...
Just reset the game.The game saves when it puts you in the hall of fame. I forget if it tells you exactly when it saves, but if developers names are scrolling along the screen it's safe to reset.
Per Ivo Beckers' comment it might not be safe to do this the first time since it's a bit different--but if you're just farming the elite four after winning once ...
If a Pokemon is level 100, unevolved and evolves by level, it will remain unevolved forever. The evolution process is started by a new level obtained and there is no way to level down to level back up. So if you get it to level 100 without evolving it, it will remain that way. Only stone and trading evolution can occur at max level; happiness/etc evolutions ...
After defeating Valerie in Laverre City, your friends will tell you to meet up near the Poké Ball Factory, at the northern part of the city. After beating Team Flare in the factory, the president of the factory will give you a Master Ball. The Master Ball is obtained in the storyline.
Another way to get a Master Ball is the Lottery Corner found in Lumiose ...
Talk to the man in the Pokemon Centre at Camphrier Town. When you enter the building, he's on the right side.
He can change your Pokemon's nickname, the same as any other generation (I presume so, as you have described)
From my experience, there is no one guaranteed place that's good for rubbing (either Pokemon or otherwise...) There is one thing you can do to make sure raising your Pokemon's affection though.
When you touch your stylus to the screen to rub your Pokemon, watch their expressions before you actually rub. Whenever their eyes form an upside-down U, that's a ...
It's the last box you left the Organize Boxes/etc menu on or, if that box is full, the next box with available space.
To avoid them being dumped in the wrong boxes, move your PC back to the "dump" box (which I usually put at the front of the boxes)
