My little sister was watching "The Wrath of Dark Kat" for the first
time last night- and she noticed how much Razor and Hard Drive
looked alike. She was wondering if they could be long lost brothers.
You're probably referring to "Night of the Dark Kat," as Hard Drive
doesn't appear in "Wrath." Tho I don't really see Hard Drive
looking *that* much like Razor, other than perhaps having a similar
shade of fur color.
Also, I noticed that the animators who work on SwatKats happen to
draw Razor differently every episode. Go figure?
The animation varies according to the studio (Hanho versus Mook) and
sometimes even *within* the studio, depending on the animator(s)
involved. A comment I made once to another katfan a few years ago was
how the first season's Mook-animated episodes seemed to have T-Bone
and Razor more off-model than Hanho Heung-Up did. The response I got
was something on the order of "well, if you'd had seen the early model
sheets, you'll know why T-Bone and Razor were drawn the way they were."
