Every perfect bad guy must have some evil flunkies along for some comedic relief. Julian is no exception.
Since I'm not so forthcoming as to let you know their names, I'll describe them by their most blatanly obvious characteristics:
The one on the left is the "Strong One". He's tough, rightly evil (or is that wrongly) and loyal to Julian. Unfortunately, he's not big on brains.
The one in the center is the "Leader Guy". He's not as tough as the "Strong One" but he's got brains to make up for it. Julian was right in letting him lead.
The one on the right is therefore, by default, the "Wimpy Dude". He's not as wimpy as he looks, physcially, but he's a pushover. All the "Strong One" has to do is glance at him and he'll go crying to his mama. "Wimpy Dude" is the one who has to carry the supplies, and he's the one who's defeated when Matt and Kali face them head on in a fight.
Oops, did I give away something? My bad! If you want to know more about the evil triad, we first see them in part three of Future. (The aforementioned fight scene is not yet posted as of 07-24-01).
