True Last Boss / TLB

The exact requirements to trigger Blacker Kram (the TLB) are unknown. But, it´s probable that Il Grande Cocomero (the Stage 3 Boss) must be defeated on Rank 5.

It has really large health, and it´s nearly impossible to beat without a time-out.


  • The upgrade bar mechanic is inspired by Gradius.
  • Il Grande Cocomero and Blacker Krams´s low HP final attack is majorly inspired in Gengetsu´s infamous time-out pattern.
