Obviously, Problem Sleuth is peak. Hell, I think the titular character has evolved into something of a Blorbo for me. I don't know if people even use that term outside Tumblr and maybe Twitter. He's The Character. That one fictional guy you obsess over. I think his cameo in the Beyond Canon bonus pages gave me enough psychological depth to latch onto and completely flanderize him in my brain and make him like a deltarune secret boss or make her transfem or whatever else pops into my mind as something vaguely feasible.
