Big Body:
You know how, when you try to stand in the same place as the opponent, both of you are pushed away? Dragonite ignores this law. Only she can occupy a given space, and other foes will be pushed away instead. In fact, she could just walk right into the foe and drag them across the stage.
This is different from just being a solid wall, as opponents can still walk, run or jump past her without trouble. It's only if they idiotically stand still that Dragonite can barge em about.
Actually, speaking of "wall characters", Dragonite's power allows her to push even these braggart foes around pretty well (at about half Dragonite's normal movement speed). But, again, this is only if they remain motionless. Once they get on the move, even Dragonite will need to give way...
Momentum Character:
Dragonite looks like a big lug, but she's actually a lightning bruiser just waiting for a chance to shine. Don't mock her! Dragonite is a sensitive Pokemon! Oh look, now you made her cry!
Dragonite increases her movement stats by, obviously enough, moving a lot. The lardy Pokemon gets incremently faster. Rather than accelerating, Dragonite "switches gears" after moving around enough, suddenly becoming faster, on land, sea and air.
You could level this up from Dragonite's base 80 speed, up to a dizzying 145 speed (almost doubly fast!). And that takes about 13 seconds of constant motion to pull off.
There is a problem with this however; if you let Dragonite stop still, you will rapidly lose the extra speed she had gained, returning to her docile ways in a matter of seconds. If you want to be the fastest Dragon, you gotta keep on truckin'! Don't stop the rock, and plough on through any obstacles in your way!
Multiscales:
Dragonite is one tough cookie! Her robust hide deflects 3% off of every strike that hits it. If the attack dealt 3% to begin with, it clanks off of Dragonite's bouncy belly, rendering them vulnerable to attack.
Unfortunately, this astounding power only works when the Pokemon is standing completely motionless. When moving, Dragonite's ability to deflect pain quickly drains to zero, rendering her just as vulnerable as any other tub o lard. Its effectiveness drains at a rate of 1% per half second, so after 1.5 seconds, you'll need to stop still again to get her Multiscales back.
Just like with Dragonite's "Momentum" ability, Multiscales will grow stronger, the longer you spend motionless. 7 seconds is the magic number this time, and it'll bring your ability to deflect attacks up to a super 6%, which is a lot.
Oh, but we can do better still.
Dragonite's multiscales also have an inverse relationship to Dragonite's shield; when her shield is close to breaking, or even already broken, her multiscales add another 3% armor onto her bulk. Naturally, once the shield grows back, her multiscales similarly decrease back to their natural strength.
So, all in all, Dragonite could shave 9% damage off of every attack she recieves, completely nullifying anything that deals less. Grabs are still a pain though, watch out for those.
As a side note, the following things count as 'moving'; walking/dashing, rolling, jumping, fastfalling, climbing up a ladder or ledge, moving left/right in midair.
And the follow do not count as 'moving'; movement via using an Attack/Special/Throw, being knocked away, being grabbed/thrown, being forcefully moved via a trap or mind control, moving while offscreen.
As a secondary note, moving via any of the above does not count as 'standing still', for the purposes of Dragonite's Momentum mechanic. Her momentum won't increase while moving via these means, but it won't decrease either, and that's important.
