Unfortunately I didn't know he wasn't creative at the time and the writing hatred was fine, since I was going to be doing the actual work in writing out what we came up with. We originally decided to do this because he's actually pretty good at creatively using super powers, but has absolutely no idea what works within a story or how to write one.
Like, all of his characters were based around having a singularly useful ability, but they weren't like JoJo Stands with useless bullshit where there's one a week and they move on, no, he wanted these guys to be main characters and have them use their powers smartly to get out of situations. That sounded cool, so I went along with that for a bit, assuming he had some kind of plan, but it essentially just boiled down to him coming up with a couple extremely contrived scenarios where their powers could suddenly do something that would get them out of that exact situation and it was just too much.
