First off the art in the issue is a weird Mashup of the Batman animated shows and Teen Titans Go, it is not bad, but not to my taste. In other words I don’t hate it and I don’t love it.
It doesn’t distract from the story though where Robin and Superboy are duking it out with robot versions of Batman and superman. During the fight they meet Sara whose family was infected by and survived the Amazo virus.
The chemistry between Jon and Damien is awesome, funny and very reflective of the dynamics between Bruce and Clark. And there is definitely humour within this comic.
