I’m going off of deteriorated memory but… space pocahontas where the natives of the planet humans are invading are tall blue vaguely mammalian-fish looking humanoids with a weird multipurpose tail for controlling animals and apparently also for sex according to supposed axed scene. paraplegic human uses weird technology to control the body of one or something to complete the white man saves the day even thogh white man cause the problem in the first place trope. I dunno about the sequel maybe he permanently stays in the alien body or something and has alien kids, who knows.
