Random ahh thought came to mind, who'd win between these two mysterious giants?

The only correlation that I had at the time for this matchup was that Cosmos preceded Nexus and that's about it, plus they both can become Legendary Ultraman (Cosmos is only 1/2 and 1/3 but the point still stands.)

Despite mentioning the fact that they can become Legendary Ultraman..... Noa, Legend and Saga will be excluded from this matchup.

Nexus:

• Anphans

• Junis

• Junis Blue

Cosmos:

• Luna

• Space Corona

• Eclipse

• Future Mode

And that's about it.
