Never my intention my good sir! I simply wanted to know why everyone considered Kougami a bad guy and to warn you of the dangers of assuming things. You can not prove I am wrong same way I can not prove you.
If you don't indicate that the input is temporary or permanent, like Kivat or Seed of Agito, then my statement isn't wrong. I just merely didn't state it thoroughly.
I don't see what "temporary" or "permanent" has to do with it. Both catalysts are fundamentally irrational and therefore mystical in nature. Going back to Shin, while his origin is not strictly possible, it is expressible in completely rational terms and involves only the transfer of organic matter.
When I say that Shin's origin is expressible in rational terms, I mean that you can explain Shin without referencing anything that obviously doesn't exist. Both Kiva and Agito cannot be understood on even the most basic level without making reference to mystical devices that cause mystical things.
Gills was probably designed before Agito's plot was written, by someone who wasn't sure what the character would be like. The designer probably figured that Gills's design needed an element to represent a henshin belt, in case the toy guys wanted to market something like that.
