"I'm good, I'm good, I'm really, really good, I'm better than good, I'm BAD!"
-One of Simon's excited ramblings
Simon is the secondary, later true main antagonist of the show. He is a human that wants to prove to the world that monsters exist. Simon's various contraptions are often activated by a vocal commandment often beginning with "Simon says". He often sleeps to a Hypno-Sleep track he recorded of himself saying phrases such as "I am brave and capable!", "I will PROVE that monsters exist!" and "One day, I WILL catch a monster!"
Simon has a brown coat, black circular glasses and wears blue jeans. He has peach-colored skin and pink lips. His unkempt hair is grayish-black with a hint of green and splits in the middle.
