Finished all 3. LORE (because I was bored again). Character 1: Maker forgot to feed the Watcher too many times. It couldn't contain its hunger anymore and needed to eat something. Sadly, Maker came home just as soon as Watcher made that realization and was devoured whole. He is still alive however and now needs to wait for things to go back to normal. Character 2: This killer was the great great descendant of Jack the Ripper and took up the family business of murdering. One day, the victim fought back and tore his jaw, eye, and hands off. However, the killer wouldn't go down that easily and with a little help from his family, he got new weapons to murder his victims. Character 3: This is what Watcher used to look like a long time ago. They were used to replace the police as they were corrupt and dishonest. This specific model however managed to gain sentience and changed the course of history.
Designs aren't final and will change in the future
