Posting for the anon who wasn't sure and asked the other day about where Fatty and unit counting enemies look/target, Fatty does specifically look only at ops like his description says, he ignores all summons/walter revenants/etc, unlike Materialist Antagonizer who specifically targets allied units like desc says. Bit late since it took me a while to run into him to test it but just posting so he sees it. The IS6 dragon hand seemed to read targeting operators so it'll be more troublesome, can't bait that with summons unlike MA, but also won't hit Walter even with summons clumped around her.
