Named after a popular soft-drink in Japan, Kalpis is one half of the comedic duo Ramune & Kalpis (also commonly known as Tick & Tuck) modeled after classic American comedians Abbott & Costello. Usually depicted as happy-go-lucky, but bumbling, henchmen or assistants, Ramune & Kalpis often make an appearance when the story is in danger of becoming overly serious or dark. Kalpis is usually the butt of the joke, often set up by Ramune for the punch line. He’s the short, fat “Costello” to Ramune’s tall, skinny “Abbott”. Although purposefully not designed to have much of a personality on his own, as the comedian in the relationship, certain character traits have emerged. Almost childlike in his demeanur, he is extremely loyal to Ramune, and is lost without him. Much like a little bother, this often leads to him being bossed around by Ramune. Although he likes to be considerate of others, his petty greed often gets the best of him. Primarily good-natured, his cheerful dispositon can disappear into a blustering (and bumbling) rage if provoked. (Source: Tezukainenglish)
