Dogether

Overview
A strange cyclopean creature created from a forbidden spell, the Dogether mainly attacks through the use of magic. Although its spells are powerful, it takes time to cast them, and can be quickly attacked during that period. It appears to use sanskrit to cast spells.

Castlevania Dracula X: Rondo of Blood
The Dogether is the boss of stage 3'. It attacks by flying and teleporting around the room, and summoning three different rune-based spells: A three-way green laser, descending bouncing flames on the ground, and surround itself with a shield of rocks. When defeated, the Dogether chants another spell, and attempts to kamikaze itself on Richter.

In the Dracula X Chronicles remake, the Dogether is slower to cast its spells, and its flames do not bounce as much. The arena also has an extra third platrofm that Richter can stand on.

Castlevania: Portrait of Ruin
The Dogether summons itself and attacks in much the same way as Rondo of Blood, but takes more time before casting a spell, and does not cause damage during its death animation. It also has a different, less-human voice. It drops a monocle and the Rock Circle spell.
