First the Rhino Man. I call him that, although he doesn't have an official name. This mini was sculpted by the Perry's in the early 80's for the Citadel edition of Runequest. He is preslotta and is from the second set of Broo released for the game. He is actually not showing on the catalog image above, although there is a Rhino headed design there, but without a shield.
Here's the other new member of the gang: the Citadel C22 Chaos Demon. Released in 1985, this mini is a perfect Chaos mini, disturbing and creepy but also cute. It was really fun to give it a colorful paint job and the demon fits really well with the C38/C27 vibes.
