Mister Terrible

Mister Terrible clearly takes his costume and moniker from Mister Terrific, and wears a similar costume with a "T" on his face, and a leather jacket with the words "Foul Play" written on both sleeves. Of note is the fact that he uses the original Mister Terrific's color scheme of red and green, rather than the modern Mister Terrific's red and black color scheme.
