What about Dyna - Max ? How strong their power compare to New Heisei Generation ( Ginga - Z )
Dyna has been, still is, and will always be stronger than Tiga. Even now he still has a statement of being superior to Tiga. And so far other than the Ginga S movie he has only appeared in Origin Saga which takes place before the New Generation Era.
Gaia V2 is still shown to be comparable to Multi Tiga and Flash Dyna during Ginga S. He’s honestly probably somewhere in between that lvl. Supreme Version is seemingly shown to be comparable to Power Tiga and Miracle Dyna. He hasn’t appeared anywhere else since Origin Saga so there really isn’t anymore scaling.
Agul V2 will always comparable to Gaia V2. That’s it. He doesn’t have any other forms.
Cosmos believe it or not is probably the current strongest Heisei Era Ultraman next to Zero. Luna Cosmos is often shown to be comparable to Base Dyna so it shouldn’t change during New Generation. Corona Cosmos is also pretty much comparable to Strong Dyna most of the time. Eclipse Cosmos on the other hand has no real feats other than tanking attacks from Etelgar. But Future Cosmos seems to be able to defeat Leugocyte in Ultra Galaxy Fight 2. And Leugocyte has a really long scaling chain.
Justice has no feats in the New Generation so far. And I don’t remember how strong she was during Cosmos’ series. So no comment
Nexus is also seemingly stronger than Tiga, Dyna, Gaia, and Cosmos at least in terms of Base form due to the tower climb statement saying the higher up the tower they go the stronger the enemy. Junis Nexus stomped Eteldummy Dark Mephisto who is supposedly superior to Eteldummy Five King since he was after Five King. Although this might not apply to Five King as it wasn’t actually in the tower. In Ultraman X, Anphans Nexus is also shown to be comparable to Base X.
Max is far stronger than Anphans Nexus, Base X and etc. He fought Alien Sran who was after Dark Mephisto in the tower and pretty much stomped him. He was also able to withstand attacks from Zetton Armor X, Zetton, and Alien Sran at the same time and his color timer still won’t start flashing. So Max being stronger than even Junis Nexus during the Ginga S movie is very likely a thing. He hasn’t appeared since than so yeah thats it. Now we wait for Ultra Galaxy Fight 2.
Mebius has the statement of being superior to Max during the Mega Monster Galaxy Era. And in the movie he fought Alien Empera who was also after Alien Sran. So Base Mebius is also very likely stronger than Max. Which makes sense since these days all members of the Ultra Brothers have been given a huge buff by New Generation. Burning Brave one shot Eteldummy Alien Empera who is superior to the original Alien Empera.
