Krookodile

Krookodile is capable of expanding the focus of its eyes.  By doing this, Krookodile can see objects off in the distance as if the eyes were binoculars.  Krookodile never lets prey escape, and has fangs that could crush the body of an automobile.
When I first say Krookodile I was like "Woah, this thing awesome- I should SO use him!".  His design aside, Krookodile has good HP.  He just has low Sp. Attack, and that's it.  He has a good amount of Physical Moves, so you don't need to worry about having too many Special Attacks instead of Physical Attacks.  He has a normal amount of Defense, Sp. Defense, and Speed.  He has pretty good stats overall, and, if used with care, could be a potential monster.
He has Crunch- A good Physical STAB move.  He can use Dig and Earthquake, other great Physical STAB moves.  If you're really daring, you could try giving him Outrage, but if you want a different Dragon-Type move on him that confuse him, just give him Dragon Claw.  Krookodile can be bred with Counter, which can be a dangerous move at times.  He also has Foul Play, which is more powerful the higher the target's Attack stat is.  If you know your Pokemon very well, you could use Foul Play really well, too.
Krookodile has two abilities, both in which aren't too bad.  He has Intimidate.  When Krookodile is first sent into battle, he lowers the opponents Attack stat by 1.  It's not bad, but I like his other ability called Moxie.  If you take down an opponent's Pokemon, your Attack stat goes up by 1.  My Krookodile has Moxie and friend's has Intimidate.  Either way, they're both good abilities.
Krookodile has a great design, movepool, Attack stat, and everything.  I think Krookodile can be a threat to opponents when in the right hands.
