whats the difference between optima red yellow and blue top batteries?

Red are mainly used for all basic car and truck applications with standard factory features and the Yellow is mainly used for deep-cycle power needs when adding performance audio, inverter power, security system backup and winches and the Blue is mainly used for marine use in boats....

Blue and Red are the same except for the available Pokemon in the world. However, Yellow makes you to start with Pikachu and Pikachu actually follows you around outside of it's Pokeball. And Yellow is slightly better in graphics. I'd choose Red as my favorite, only because I never played the others much.
