Gary- Gokou (DB/Z/GT)
Okay, I just couldn't resist this....
Do you not see it?
Big
Dumb
Like to eat alot...
Not the brightest crayons in the box...
And yet, they are very powerful (Well, Galzzy is anyway ^.^ )
They can sometimes show their emotional side, but usually they just prefer to have fun, eat, fight...
And then eat some more.
Kevin- Chibi Trunks (DBZ/GT)
Deceiving
Young
Mischevious....
In a word? Trouble.
This would probably have to be the best and most accurate match on the entire site.
^^
They have a knack for getting themselves in deep, and they aren't afraid to cheat their way out of it.
They are both extremely advanced in the art of manipulation, but never fail to keep their word.
OTHERS
Some of the lesser characters
Mr. Dickenson = The Monopoly Guy = Santa Claus 
WHY All round, jolly fellows who can give you everyhting you could ever dream of (A place in a high ranking Beyblade Team, countless bank notes-even if they are fake, and presents...) and then snap it back in an instant.

Mr. Granger (Tysons Grandfather) = Mr. Hida (Cody/Iori's Grandfather- Digimon 02)
WHY Can you say deluded old fools? Okay, so not all the time. They do have their moments of inspiration where they guide their grandsons through life...But other than that, they are just plum crazy (Granger- His 'hip and modern' ((yeah, right)) way he speaks, Hida- His obsession woith Prune Juice)

Mr. Tate (Max's Dad) = Janyu Wong (Henry's Father- Digimon 03)
WHY Because they are the caring, knowing fathers that everyone would want to have. They can be strict when they need to be, but are also kind and thoughtful. Awww

Judy = Mystique ( X Men)
WHY These two dont mean harm to their sons (Max/ Kurt aka Nightcrawler) , but they sometimes cause it..... They aren't all that bad when it comes down to it, they just tend to put their career before family.

Emily = Jessie (Pokemon)
WHY Okay, whoa. These two are cocky, intelligent (most of the time anyway) and will do EVERYTHING in their power to get what they want. They really dont give a damn about other people, and seem much too self absorbed for their own good. ;)

Michael = Bit Cloud (Zoids)
WHY *cough*showoffs*cough* These two guys know they're at the top of their game, and love the limelight. They aren't afriad to say what they think and can often get themselves into trouble with their Team Mates because of it.
