Most hated Maplestory monster?

Male Boss that randomly spawns in Showa Street 3.

It kills so many people who just want to walk to Showa. It also tends to blend in with the other monsters in the map so it isn't easy to spot.

There are reasons you walk on the top part of that map...

I personally hate Memory Monks. Their 999 quest isn't even worth my time right now, with their stupid 1500 ranged magic attack. I also wasn't aware you couldn't use return scrolls at TT, so I ended up losing 6% a while back when playing around and running away like mad. Ugh...
