OK, well here, we'll do pics. Juggernaut from DC comics is a good representation. He pretty much stands for an unstoppable force.And Wyvern was a big winged serpent.
well i was thinking of tentaclear being derived from a medusa. if you stare in a medusas eyes you turn to stone and tentaclears atacks all have to do with vision. they also have snake hair and tentaclear have a lot of extending tentacles.
Griffon is not a griffin, because a griffin has the frony half eagle, the back half lion. Manticores have i the other way around, like Griffon. So, Griffon is a manticore.
