Revenge of the Ninja (1983)

Revenge of the Ninja (1983) follows Cho (Sho Kosugi) and his young boy Kane (Kane Kosugi) who leave Japan after their family is tragically killed by ninjas. In America, Cho opens a doll shop, but unbeknownst to him, his trusted friend Braden (Arthur Roberts) is using the shop as an undercover drug smuggling operation, hiding heroin inside the dolls. When Cho becomes privy to this betrayal, he knows he must return to his ninja roots and prepare for the ultimate battle. A little over a half an hour in, Arthur goes shirtless, showing off his beefy bod as he tries to get fresh with a lady, first tenderly, then less so. He gets up to answer the phone, still bare-chested. Just a little earlier, an uncredited Brandyn Cross plays a condo resident that is also shirtless trying to get frisky with a woman. His fate is sealed though, after he's shot in the back of the neck with an arrow before falling naked on to his lady in the bathtub. We get a peek at the top of his butt and another as he lies dead, with some strategically placed suds covering the rest.
