Continuing from the Beux drawing, these are four of the 8 bosses of the game you'll encounter. If you can read my handwriting, fullview the drawing and you'll get a few details of them. If not, then I'll type what's written here.
Top left corner: Neon, Use: Studying and research of chemicals. Personality: Cold-hearted, but erratic. Likes to see how things react.
Top right corner: Bismuth, Use: Using magnets to study zero gravity. Personality: Due to working around magnets, Bismuth has become somewhat bipolar, prone to a change of personality at any given moment. One side is bashful and shy, the other violent and tempermental.
Bottem left corner: Cobalt, Use: To mine, process, and apply the use of ores. Personality: Impersonal and hard-working. Likes to work. (Workaholic)
Bottem right corner: Radon, Use: The mantainance and use of steam power. Personality: Being the first AIU, Radon isn't very bright. Clumsy, but very respectful.
