They often refer to themselves by their titles.

Super,who looked like Sonic with amber-red eyes,was playing poker with Fleetway,who looked like regular Sonic with Fleetway eyes.(Their First Meeting) "WHAT ARE YOU DOING OUTSIDE YOUR CAGE,INSANE BASTARD OF A BROTHER?!" Super Sonic screamed at Fleetway Super Sonic. Fleetway Super Sonic said,"N-NoT mY fAuLt,LitTlE bRo...It'S tHe FeAr CoMbInEd WiTh ThE nEgAtIvE cHaOs EnErGy,It...CoNtRoLs Me."

(Now) "Hey Fleet,should we be checking on Sonic?" "NaH,i'M sUrE hE's FiNe,SuPeR." Suddenly a chill came over them. "You feel that?" "YeAh,It'S nEgAtIvE cHaOs EnErGy.ShOuLd I cOmE oUt?" "No,Fleet,you come out when he feels fear and has a negative Chaos Energy dosage,but right now,he's feeling...rage." The two personalities looked at their shadows,which pulled away from them and combined.Out rose Sonic with black fur and deadly jade eyes,not the usual cheery emerald.Then he screamed out,and his spikes rose as his eyes became pure white,his skin a lighter shade of black than his fur,but then he turned transparent,which meant his power was being called upon.Super and Fleet looked like themselves as you often saw them because they powered up to not be sent flying.Super walked over,and said,"We'll call you Dark.Wanna play poker? Not much else to do." The newly dubbed Dark nodded and mentally summoned a deck of playing cards.
