I have an evil twin name game I play. I look up the meanings of names, the look up names that mean as close to the opposite as I can.
Sicco Thermaplugg, my evil twin would be Madefacio Frigipump!
Sicco = Latin for Dry
Thermal = Relating to heat
Madefacio = Latin, to wet
Frigid = Cold
Pump = A device for moving or compressing a liquid or gas.
Terran Justice Gregory‘s evil twin would be Caelestis Nefarious Cecilia
Terran = derived from terra, the Latin term for Earth.
Gregory = Greek name “Γρηγόριος” (Grēgorios) meaning “watchful, alert”
Celeste = In Latin is: Of the heavens; Heavenly. (Heavens would be opposite of Earthly right?)
Cecilia = from Latin caecus “blind” (Since Gregory means “Watchful” and “Alert” blind seemed appropriate)
