Temptress
Temptresses are colossal enemies that appear in 
Mausoleum. Similarly to 
Gary, it will emerge from a set point on a wall after a period of time passes or once all enemies are killed. Afterwards, it will leap out from the wall with a bellowing roar and chase after Isaac; dragging itself using its arms, and only being able to move in steps along the cardinal directions.
After a few moments of chasing Isaac, the Temptress will start becoming enraged, signaled by a eerie growl as it starts speeding up. After catching up to Isaac or enough time has passed while enraged, it will stop in place and slam its fists down, sending out a 2 spiraling rings of 4 spectral projectiles which rotate in opposite directions as they travel outwards. After this attack, the Temptress will calm back down and return to its starting speed, before repeating the cycle.
If any destructible obstacles prevent Temptress from reaching Isaac, it will smash through them as it moves. If it is completely unable to reach Isaac, its expression will change to a thin grin and it will remain stationary. However, Temptress will still be able slam its fists and shoot out projectiles even if it can't reach Isaac.
Upon death, it will shoot out a volley of blood, bone, and teeth projectiles in the direction it is facing.
Temptress will deal a whole heart of damage on contact and with its projectiles.
