Cat or charr or whatever, Kaiba knows an engineer when he sees one. After satisfying his curiosity by touching The Thing, he watches it retreat to Ferroc's shoulder.

Hard to trust a creature that big and that toothy.

"Not really that impressive," he points out. "I'm not really that fond of weapons. I invent other stuff."

Better stuff, he'd argue, but he is dangling a hook: their respective fields were one in the same, if meant for different ends.
