As a cranky villager, Cesar will appear mature compared to other personality types. This will make him appear belittling and insensitive to other villagers, including the player. He will enjoy the usual hobbies, but for relaxation and peace than competition. He will find it difficult to socialize with peppy and normal villagers, who he will criticize when talking to other villagers. Cesar in fact finds it difficult to socialize with any other personality including other cranky villagers. Sometimes he will come to your town appearing somewhat friendly especially towards the player. But this is rare. The bad news is that Cesar often comes to your town acting completely nastily towards everyone. He can even upset other cranky villagers and will often stay in his house. If you annoy him (push him, hit him with a net, say something mean or worst of all, trap him in a pitfall) there will be almost nothing to do which can improve your relationship with him.
