2)Triton-Temple Warrior (infantry)
3)Siren-Devilish Siren (flyer)
4)Huge Crab-Armored Crab (infantry)
5)Octopus-Kraken (infantry)

8)- This one is a secret for now
Hmm... doesn't it seem like Krakens and mermaids, as well as tritons and other aquatic beasts, like sea serpents, are something that "remotely resembles" Disciples2? ;)
