10 RPS Mechanic: He will rush to the last room and stay in the middle for 3 seconds. then he will dissapear but also playing a laugh sound. after it he will roll a randomized chance to spawn A-1 or A-10 [A-1 is 2 in answer. A-10 is in 4. its 2/4 btw]. theres also a another chance of it not selecting a entity to spawn
C2A this entity looks easy for me to code btw the N variant is supposed to be green and the sound 2 times faster. also with X eyes and more sinister smile. you can try recreating him with kleki easier so you dont experience lag
