How to unlock the The Most Dangerous Man on Earth. achievement in LEGO Batman - Definitive Guide

I have just got this achievement and you need to do it on Story Mode. Also you must make sure all EXTRAS are switched off and that the final blow is from Batman (Not Robin)

The levels you need to do are

Stage 1-5 - Two Face and Riddler
Stage 2-1 - Catwoman
Stage 3-5 - The Joker

Actually, you can do this with Extras on. I had all the stud multipliers on, and it popped when I beat the Joker.

I can confirm what RitzOmega said. Extras can be on. I had everything on when I did this. Just make sure you are on story mode and not Free Play.

I also popped this with a bunch of Extras on. I had on the stud multipliers, the minikit/power brick detectors, and the stud magnet. Not sure if having stuff like regenerate hearts or invincibility would block the achievement, but I doubt it. I can understand leaving them off to be on the safe side, though.

I can confirm that you CAN do it with extras on as well. I have been using extras for almost every single level.

My nine year old got this on his first run through - the reason? He likes Batman better than Robin. Sounds daft but that is all you need to get this first time. Don't make my mistake and keep switching and end up having to back for it.

Interesting fact: I got 100% Completion WITHOUT this achievement. This was the last one I got.

The 100% Completion acheevo only related to the Characters & all Extra's unlocked, Minikits, Red Bricks, True Hero on all Storys Hero & Villian & Wayne Manor Bonus level.
When I played Lego Star Wars I had gotten the 100% acheevo with still 10-15 acheevos left.

To get this achievement, you have to defeat Two-face, Riddler, Catwoman & the Joker as Batman.

This can only be done through story mode so it would be easier to try and get this achievement first time around. I attempted many times to get this achievement through free play thinking my game was broken, lol.

You can complete this achievement with all extras turned on, so if you do have to come back and replay story mode, it will be much easier.

You should get this after finishing the final Hero mission, just make sure that during your boss fights, you make the killing blow on each of these chracters while controlling Batman. If you kill them while controlling Robin, the achievement will not unlock. Replay the necessary story missions in Story Mode if you messed up.

  • Joker: To the Top of the Tower (Episode 3, Chapter 5)
  • Two-Face: The Face-Off (Episode 1, Chapter 5)
  • Riddler: The Face-Off (Episode 1, Chapter 5)
  • Catwoman: There She Goes Again (Episode 2, Chapter 1)
