Glovatrix
From Multiversal Omnipedia
The Glovatrix was a device worn by each of the Swat Kats on their hands. The Glovatrix was armed with several tools and weapons, including a grappling hook, a device to crack password codes, and tiny missiles.
Alternate Timelines
The Dark Swat Kats in an alternate universe also had a Glovatrix each, but theirs were heavier on the weapons and covered in spikes.
