Flim-Flam is a clever street child, he briefly joined the Scooby-Doo's gang to assist them in returning all the most terrifyingly powerful ghosts and demons back into the Chest of Demons. He was voiced by Susan Blu who also voiced Arcee.
Flim-Flam is a tanned Latino child, with an unkempt mop of black hair. He wears white and red sneakers, a red under-shirt and a yellow tracksuit. His pockets can hold an impossibly large amount of items. He stands about a foot taller than Scrappy-Doo, but often slouches so can appear smaller or taller.
Flim-Flam is, as his name implies, a born scamster and opportunist. Although tremendously ambitious, he doesn't seem to be above bilking and bamboozling people for his own profit. While he is more or less on the level with his friends, he does tend to exaggerate his abilities and past deeds.
He is also a know-it-all and cracks quips and jokes more often then the rest of the gang, and seems quite confident in his (rather proficient) ability to smooth talk his way out of a situation (usually prefaced with a smarmy, "Hiya, neighbor! What can I do ya for?"
He proved to be an extremely loyal and useful member of the team. Even early on, before he was an official member, he was able to cure Daphne Blake of werewolfism using his Lotsa Luck Joy Juice.
Out of the gang, though, Flim-Flam has a close brotherly relationship with Scrappy, due to their common youth, shared intrests and short stature. Eventually he earned himself the affectionate nickname of "Flim" from Scrappy. However, Vincent Van Ghoul seems to have a bit of reservation and doubt dealing with Flim-Flam -- probably due to Vincent being all too aware of Flim-Flam's shady tendencies.
