Razid's designs were drastically different than it's current one, it originally was brown and blue, had a more jagged mouth, had cutesy blue eyes and it had 2 long blue toes that it appears to be standing on the top of them. It was most likely changed up to how it is now to reflect the Electric Type more in it's design.
Raizid is based on a running lizard and a punker and the spikes on it's head forms a mohawk, which is a hairstyle associated with a punker. The Shiny gives off a Neon look which references how punkers would dye their hair in different bright colors.
Raizid's name comes from the words Rai (Japanese meaning thunder) and Lizard or kid.
