My friend George have a retro game shop in HK,where his shop logo was just featuring some generic fonts. About their origin, well George made a funny face with blutacks as a temporal mascot,which is used as the base of Riko and Sety's face!

Originally, the mascots only consits Emac and Nur - old name of Riko and Sety(a reference of Proco and Tiat with reversed spellings of Taito Corp). Turns out quite easy to forget thier name so the new ideas were surrounding RGB, game company and CPUs

Riko and Sety's old design is pretty much a pallete swap, so i redesigned Sety's horns to give him a distincted look

Reon do also have a few of concepts(My FB album), he's a pet/vehicle themed character, based on Rush, Yoshi,Auto Vajin and BuCue(originally with Galleon).His colors are based on Yoshi,Doomguy and Master Chief.

wow i haven't wrote things like this long for a while, hope you will like their final designs
