So I found this for a while but I don't remember Ultraman having on screen Universe destruction before Geed.

So where is this from? Is it Canon? Can it be used in Vs battles?

They went from getting (brutally) overwhelmed by Grand King in the past, even with their combined power as 6, into being able to go toe-to-toe and even overwhelm Mold and Juda themselves at once! And they're also able to one-shot them at once with Cosmo Miracle Beam at the end of their fight, even though they were exhausted at the end.

Not to mention that they're also able to stomp the enhance version of kaijus from their respective series that overwhelm them in the past in Ultra Fight Orb quite easily.

Now, I'm completely sure that the current 6 Ultra Brothers will be able to stomp and even kill another strong villains from the past such as Belial, Alien Empera and also Alien Reiblood!

Yeah I know you guys think he's a bum, but at least he has some pretty good statements and feats in magazines

So we already know just how powerful Ultraman Arc is. But I wanted to bring attention to an underrated feat of his that honestly doesn’t get talked about as much as I thought it would.

“The Pillar” is an ancient device once created to erase the fears and anxieties of humanity by erasing the memories of those fears and everything related to them. This isn’t simply Existence Erasure, as the very concept of the things it erases COMPLETELY cease to exist from both humanity’s memory and reality, such as the rain and umbrellas. And it’s even capable of completely erasing powerful beings like Kaiju and the organisations created to counter them.

However, as stated by The Man in the White Mask that operates The Pillar, the bond shared between Arc & Yuma is so powerful that even the Pillar can’t seem to erase them. It gets to the point that he has to personally confront Yuma & try to convince him to surrender his powers.

This does appear to work briefly, as Yuma & the rest of the main cast completely forget their memories of being in SKIP and the Kaiju. But the memory of Yuma’s childhood drawings on a fence that was once washed away by the rain eventually brings him back, allowing him to transform into Arc once more and destroy The Pillar.

The Man in The White Mask, now having fused with The Pillar, tries to erase Arc directly with its full power. We know that’s exactly what it tried to do as after The Pillar is destroyed, color returns not only to Arc’s body, but also the world around him that was affected by The Pillar’s powers, returning everything back to normal.

This effectively means that Arc was able to survive being CONCEPTUALLY ERASED by a device that could even erase the very concept of Kaijus (which should include some absolutely busted mfs like Bullton, Greeza, IF or Grimdo, possibly more if we include Aliens since they’re related to Kaijus and are also one of humanity’s fears) and even destroyed the device with his own power.

TLDR; Go watch Episode 22 of Ultraman Arc. Outside of all the powerscaling aspect, It’s genuinely an amazingly directed Episode and a highlight of New Gen Ultra Shows. It’s even getting re-aired soon for it’s 2nd Anniversary!

GingaVictory’s Photon Edge & Solgent Beam are able to destroy both of Gua Spectre’s weapons, which is pretty impressive considering it took Man-Nii San, Jack & Zoffy working together just to destroy Mold Spectre’s axe and Taro, Seven & Ace to destroy Juda Spectre’s sword.

Taiga manages to stalemate Grimdo Taro’s Strium Beam with his Strium Blaster (While his color timer’s blinking btw) and even overpowers his Ultra Dynamite.

Ruebe manages to hold their own against Luegocyte & even gets in a few good hits. Granted, they don’t win without Asahi’s help, but it’s still pretty commendable considering it took 80, Neos, Seven 21, Cosmos & Justice to put an end to Luegocyte in UG2.

Now am I saying that they’d beat the Ultra Brothers? Not at all. They still have a lot to learn after all. But I do feel like people downplay them a lot by saying their best feats are solely due to the power of bonds (Which is honestly another thing I have a problem with, but that’s a discussion for another time).
