Lex Luthor / Joker | Boss Fights and Tactics LEGO Batman 3 Guide

The fight against Joker and Luthor appears in the mission Space Station Infestation. When fighting Joker and Luthor use Superman's skills. He is "immortal" so he cannot be hurt in this fight. When Luthor sends his henchmen against you, destroy them, and as soon as you do, fire at him with a laser. Luthor will try to avoid your attacks, so you have to move the gunpoint after him.

When Luthor's health drops to about 30%, have Superman fly up to the higher platform and destroy all the bricks there (gold objects can be destroyed with a laser). Use them to create a platform for Batman. Then fly down to the lower floor and use bricks to build a generator in the center. In order to use that, you have to move Batman to the higher level and destroy the glass with the Sonar Suit. Collect the token that drops from there and wear the Electricity Suit. Before you go down approach the generator and gather power from it. After that go down and transmit the power into the generator in the middle.
