King for a Crazier Day

King for a Crazier Day was announced in the 4-1-20 CSR Productions Direct, and is the sequel to King for a Crazy Day.

Development
The tournament was apparently brainstormed for a while.

In the 4-1-20 Direct, a teaser was shown showcasing Nero from Devil May Cry looking on the returning veterans, similarly to the reveal of Super Smash Bros. Ultimate. Weiss and Dedede were hinted to return.

In the King for a Crazy Day Development Slides, a full reveal trailer was shown, similar to the trailer for King for Another Day. The Veterans were shown off with some having unknown partners. Nero was also shown with Dark Pit to join forces as "The Angel and Devil".

On April 11th, the Gala Dragalias were revealed. On April 20th, Richter was revealed.

On April 27th, Nero was removed from King for a Crazy Day and replaced with Vergil. The team would still be called "The Angel and Devil", albeit with different sources.

On May 4th, the Brick Masters were revealed, and on May 27th (initially planned for the 23rd), Chihiro and Marnie.

During E3 2020, the Krocodilian Kaptains, Tatusmaki, and Yzma were revealed. Mojo posts slowly began to release.
