Catoblepas

Castlevania: Circle of the Moon
Similar to Gorgon.

Castlevania: Dawn of Sorrow
Catoblepas appears few times in the Garden of Madness. They are very slow, so killing them is not a big deal.

Their soul allows Soma to create clouds of petrifying gas, which can turn to stone many enemies, and allows Soma to do +50% damage if the target actually turned to stone.

Castlevania: Portrait of Ruin
Similar to Dawn of Sorrow. They appear in Sandy Grave.

Castlevania: Order of Ecclesia
Though there is no « Catoblepas » in the game, a certain monster called « Gashida » acts similary as Catoblepas - that is, moves slowly and breathes petrifying gas clouds. This one also jumps on you, and that's no laughing matter.
