Raven vs Starfire
Raven and Starfire, widely known from their time on the television adaptation of Teen Titans, are as opposite as opposites can be; while Rachel Roth is quiet and reserved, Koriand’r is outspoken and enthusiastic, and their appearances express their personas as well as their powers.
Starfire’s powers are typical of a Tamaranean: super strength, super speed, flight, durability, and the ability to emit destructive “starbolts” from her hands and eyes. She is physically superior to humans in every way, and her powers are driven by her emotions; her passion is what fuels the power behind her abilities.
Raven on the other hand, has darker, more arcane power. Along with telekinesis, Rachel can teleport, manipulate shadow, heal herself, and most importantly, rob the emotions of other beings.
With her emotions drained to nothing, Kori would be a sitting duck waiting to get roasted, but it’s not so easy for the half-demon. As a Tamaranean, Starfire’s reaction time would be much faster than Raven’s meaning she could essentially speedblitz her with a devastating eye-blast. IF Raven somehow dodged/blocked/survived Starfire’s initial attack, the fight would be over. At that point Raven’s demon-half would engage and drag her teammate into crippling emotional depths and snuff out her life with ease. If she survived the first strike.
