In Shin Megami Tensei, if the first thing you think of is they made this creature look like a penis driving a cart, your first assumption is typically correct. There isn't a lot of half-assing or tippy toeing around shit in the art direction.
I've never played any of them but I've seen official art of monster (i.e. the above link) after monster that's either got a huge erect penis of some sort, or is a huge erect penis of some sort.
There also seems to be a lot of Nazi homage shit too. Hmm.
