Doraemon and Suneo are good friends. He also cares for him like he does for Shizuka, Nobita and Gian and tries to keep them out of danger. Doraemon is one of the few who does not get bothered by Suneo's boasting, but instead takes out an even cooler gadget to show Suneo. However, at times, Suneo will find ways to irritate Doraemon, such as altering a photo of him to make him look like a tanuki which literally made him turned red in pure anger, or when Suneo dreamed about Doraemon being a worthless robot he found from the dumpster and then repaired to act as a idiotic friend. He even tricked Doraemon with the fake stick of gum trap, which totally enraged Doraemon to the point of seeking vengeance against Suneo for making him look stupid. This also applied when Suneo exploited Doraemon's weakness for dorayaki while using his gadgets for his selfish purposes and not giving him any dorayaki at all. Doraemon is also disgusted by Suneo's blatant disregard environment when Suneo dumped garbage into the ocean. Suneo used to be jealous of Nobita because he has a cool robot cat ( I, Honekawa Doraemon ) but it is shown now that he is pretty happy with his own friendship with Doraemon, and does not envy Nobita as much anymore.
