Cherno beat me to it, but I would like to see a big guy or gal on a 'hoveround' stolen from the local S-Mart. Lady would be in a muumuu, guy would be in sweat pants and a wife beater. Maybe with a WW2 helmet on. For a weapon, a cane or umbrella, perhaps with a bayonet attached.
Local gang thug with pants hanging around his ass, ball cap, starter jacket. Weapon could be anything from a pistol to a ball bat.
Soccer mom in yoga pants swinging her designer purse.
The 'goth' kid from high school wearing trench coat and sneakers. Weapon could be some funky Klingon looking blade thing he got from one of those kiosks in the mall.
A hobo. With a SHOTGUN!

kid (pre-teen) with super soaker (filled with zombie dissolving acid!)
Scot type swinging a football helmet in his letter jacket.
Guy in bathrobe and sandals swinging his vodka bottle in one hand and a bowling bag in the other.
