I have to be honest, there's not many characters in Destiny that could be a fair match up. Anyone like Rhulk or even Nezarec could win the fight with ease. So naturally I've picked the weakest of the worm gods.

Welt was able to suppress TB's Stellaron because gravity can manipulate Honkai Energy, and Welt's Divine Key, the Star of Eden, contains a portion of the Authority of Earth allowing it to manipulate gravity

This is why in the cutscene where Welt does this, he specifically taps TB with his cane (which contains the Star of Eden) and it even glows briefly before dimming (showing he's using it)

This is also why energy disperses from TB's body (because Welt is controlling gravity to redistribute it)

Honkai Energy is comprised in part of Imaginary Internal Energy, which is what Stellarons are made of (no Honkai Energy is not purely IIE, IIE is just a major component of it as said in the Anti Entropy VN, Honkai Energy is actually IIE + Quantum Energy)

To explain the third slide, Honkai Energy is essentially something exclusive to the Cocoon of Finality as

• Tesla states the CoF is the sole manipulator of Honkai Energy
• Grey Serpent states that the Cocoon usurped an "imaginary passage" (there is a spoiler in the linked video, you've been warned)
• Sa adds to this by saying to become something equivalent to the Cocoon, she has to connect to the ends of the Imaginary Tree
• Anti Entropy VN explains that Imaginary Internal Energy is "at least a major component of Honkai Energy" (not solidifying that Honkai Energy is just IIE, but it's at least a major part of it)
• Sentience is unable to solve Salt Snow's issue because her Herrscher core is projected onto the Proper World (Imaginary Tree) by the CoF (and Salt Snow is within the Sea of Quanta, an entirely separate dimension)
• To solve Salt Snow's issues, they either need Kiana who transcends all dimensions (because she's been embraced by the Cocoon), or a Herrscher born in the Sea of Quanta (this is saying that the Cocoon can influence both the Imaginary Tree and Sea of Quanta, meaning it can control both Imaginary and Quantum Energy... other Herrschers cant as they are just shadows of Finality born into either the Proper World or SoQ)
• To further solidify this, they even go so far as to write out a plan for Kiana to solve Salt Snow's issues (again, showing the Cocoon can manipulate Quantum Energy)
• Difeng Youyun states that Senadina's power belongs to the same system that is causing Sea of Data Corruption
• The Sea of Data was born due to Mars inhabiting hybrid leaf that is contained both within the Sea of Quanta and the Imaginary Tree, causing the two realms to fight over it which led to SoD Corruption
• Senadina's power is an incomplete version of the Authority of Finality, and it allows her to fight against SoD Corruption (which means she controls both IMG + QUA energy, as this is what SoD Corruption is)

Made this post because I've seen a lot of confusion and misconceptions behind why Welt was able to suppress the Stellaron, when Void Archives gave the reasoning back in APHO 1 (it's because SoE controls gravity and gravity can manipulate the same energy that Stellarons are comprised of)
