Physical appearance EditShishimaru is a medium-sized, if not slightly plump yellow dog with brown jowls and chocolate brown ears. He also can change his shape and size, albeit only to a certain extent.
Shishimaru loves to eat, his favourite food being chikuwa, Japanese fish sausages, but referred to as chocolate rolls in the dubs. He is lazy and always tries to get out of training and he always masters techniques used in eating. He has a rivalry with Kagechiyo as Hattori has a rivalry with Kemuzou Kemumaki. He also dislikes Togejirou as he is at the centre of attention and has supernatural powers. He gets on well with Hattori, Shinzo, Kenichi and Yumeko. Despite his sloppiness, he is a dedicated disciple and is rarely seen without his master - or, if you prefer, his master is rarely seen without him. Shishimaru also has the ability of turning into a fireball when he gets angry - becoming a formidable foe when he does!
Kanzo and Shinzo Hattori EditOwned by the two brothers, Shishimaru is very loyal to Hattori and Shinzo, but there are the times when he is too lazy to pay attention to any of them. Still, they face problems together and help others endlessly. Shishimaru and Shinzo are both inseparable, often working and playing together, but there are playful arguments every now and then.
Shishimaru's workshy personality annoys the ant-like Mitsuba clan. He irks them by stealing nosh from the fridge, and spends half of his time fast asleep instead of helping out. Still, they feel that life would never be the same without this particular canine.
Yumeko is friendly with Shishimaru, and once relied on him to give her the weather forecast.
As an Iga ninja, Shishimaru detests Kemumaki and Kagechiyo for their evil plans. He is often one of Hattori's combatants in the many battles between Hattori and Kemumaki, and he and Kagechiyo fight like cats and dogs, because they are cats and dogs (or to be precise, Shishimaru is the dog and Kagechiyo is the cat).
Despite being from the same clan as Tsubame, Shishimaru is annoyed by this very stroppy vixen. She once kept him from eating many times, once because she was saving everything in the fridge for Hattori, and again because she thought that the meal she was cooking would get spoilt as he, along with the other Mitsubas, wanted to get a bite to eat.
