A Bright Future.

GREED, the traitor of the realm, gave the Tyrants advice, and it worked in helping them defeat the invaders. Unfortunately, there was a side effect of using the Taboo.

The Supreme Tyrants and their Supreme powers fused together. This fusion had to be innate, not something achieved through a Supreme Law. Fortunately, their Supreme Laws were fakes since they were not even Origin gods. 

They were Sovereigns of law who had their concepts elevated to the level of Supreme Power through the bestowal of the realm, so those Supreme Power didn't interfere with the formation of the incomplete Universal artifact. Instead, it enhanced it. So even though their Supreme Powers were fake, their ability to fuse and use multiple laws is real. This white ball is proof of it.
