Okay, this is a Dungeons and Dragons deal.
First off, for simplicity sake, let's use 2.0 rules. Prestiege classes can get annoying.
So we got Kerry. He's pretty tall, very old looking, but still participates in many sports. He's definately an Elf. And we all know that elfs get a bonus to dexterity and a penalty to strength.
Bush on the other hand is about normal height, and doesen't look too weird. So he's a human. Although Chenny would be a dwarf.
Kerry would be a Fighter, straight up I believe. He's seen combat, so I'd imagine he'd be quite proficient in the long sword (Anyone who's seen the newer version of Romeo and Juilet knows what I'm talking about.)
Bush would be a Paladan, being the great crusader he is. The class prevents him from being as proficient in weaponry, but he has the ability to cast certain spells. 3 charges of MakeUpAWord lvl 5, anyone?
I will continue this annaylisis shortly.
