Black Impulse is an ally of the Bacterian Empire and is the main antagonistic force in the Thunder Cross series.
Background[]
Black Impulse, jealous of the Bacterians' incredible forces, decided to make an empire of their own. They bought supplies, weapons and ship designs from the Bacterians for the past few years and made a powerful armada to conquer their galaxy. Their dreams, however, were crushed the chip Thunder Cross. They returned with better ships and weaponry in Thunder Cross II, although they were once again defeated.
Trivia[]
- Their Big Core-like ships have crystals as their cores instead of orbs. Even when they are not in ships, those crystal cores can attack.
