Waiting for Hank...Edit
In the chapter Waiting for Hank, when exploring Hank's desk, Connor may find dog hair on his chair. Upon analyzing them, he finds they belong to a Saint Bernard dog. If asked, Hank reveals that his dog is named Sumo.
On November 6, 2038, in Chapter "Russian Roulette", Sumo appears in front of Connor after the latter breaks a kitchen window and enters to check on an unconscious Hank. He is, at first, very protective of Hank and growls at Connor in a defensive way until the android calms him down and assures the St. Bernard that he is no threat to him or his master. From this point onward, Sumo shows no aggression or hostility towards Connor, even allowing the android to pet him while Hank is getting dressed (player's choice). He is last seen settling down to sleep while Hank and Connor head off for the Eden Club.
Night of the SoulEdit
If Connor stayed machine and Hank is hostile towards him, Hank will resign his police duties and Sumo will make a last appearance in the game during Hank's epilogue in this chapter. He will be seen sitting down on his table staring at Cole's picture with a revolver and a bottle of alcohol in front of him. Sumo can be heard whimpering during this sequence while the two talk to each other. Once Connor leaves the house, Hank will fire his gun, implying he committed suicide, and Sumo can be heard whimpering and howling.
"Gruff, big, powerful and intimidating, Sumo's fearsome exterior masks a sweet, loyal and noble nature."- Sumo's gallery description
Sumo is shown to be a good boy, acting in a calm and gentle manner, showing the true temperament of his breed, and is very kindhearted to those he sees as good, like his owner and Connor.
While he does act defensively around Hank, he does not aggressively attack people or androids, demonstrated when he is quickly calmed by Connor when the android addresses him by name and tells him he is there to help.
- Originated in Japan, Sumo is a form of competitive full-contact wrestling where a wrestler attempts to force his opponent out of a circular ring or into touching the ground with any body part other than the soles of his feet (usually by throwing or pushing him down).
