I've yet to really form much of an opinion on Zero since we're still in the earlier stages of their character development, though can't say I dislike the direction the story has taken so far.
And whilst this is, of course, entirely subjective I find Godbert Manderville more unlikeable. I don't WANT to see that idiot running around in his underpants any time he appears. I DON'T find his repetitive antics funny - if anything he epitomises the 'Overly-long Gag' trope. I can't click 'skip' fast enough any time he appears.
I just want that pointless Chad-meme, overly-long gag trope, character to disappear - or at the very least just keep his damn clothes on for once!
