Does the original Japanese text refer to the Demon Realm as a universe? If that's the case, then it could be evidence that the Demon Realm is at least universe-sized, if not larger.
Base Vegeta was holding up against Gomah and actually hurting him, SSJ3 Vegeta was strong enough that he was low-diffing Gomah who seems to just have endless stamina and some manner of regeneration, even after losing SSJ3 and being extremely tired, base Vegeta was still holding up against Gomah pretty well. This is the same Gomah who fought SSJ4 Kid Goku, SSJ3 Kid Goku, SSJ2 Vegeta, Piccolo, Duu, Kuu, Piccolo, and Glorio, beating all of them while immediately recovering to full strength afterwards and getting much stronger.
Base Vegeta as an adult in Daima is arguably stronger than SSJ4 Kid Goku, and is comfortably far stronger than SSJ3 Kid Goku, who would beat any and all of the Tamagami's, maybe even all at once, who individually are stronger than Dabura was in the Demon Realm. So pretty safe to say that Goku and Vegeta in base after 1 year alone would humiliate Dabura. Using the SSJ multipliers you could also make the argument that as kids they must have been hundreds of times weaker at least, which explains why they seemed way too weak whenever they were fighting the random creatures and soldiers of the Demon Realm.
Goku lit up all of Makai with Ssj4 and the brightness was even shown in all of demon realm.
I’ll be real, I don’t think there’d be anything explicitly contradicting Hyper Mega Rild being SS Vegetto tier. Super Baby 1’s statement felt more like a general “strongest guy ever who surpassed everyone before him, no exceptions” than a “stronger than this guy in particular”. We just give Vegetto the benefit of a doubt, which is kind of understandable
Base Goku vs Base “Stronger than Boo” Rild was as even as I remembered, with Goku getting the better of him due to basic tactics. To Rild’s credit, he was fast enough to dodge the brunt of that Kamehameha.
Episode 19
Time: Roughly 17m55s
Context: After Rild barely dodges Goku's Kamehameha
Goku: “I guess it ain't going to go that easily. You're pretty good to have avoided that Kamehameha at the last moment.”
I guess you could use that to put even the initial stages of Third Eye Gomah as stronger than Boo. Gomah when he fought Adult SSJ4 Goku should be a no-brainer because he was actually relative to Goku for a bit
@Gordo brought up in NF that this had a pretty similar beat to the Beerus BoG base Goku statement thing, and I think that's a good point to bring up
This is the same special that had Tarble say Avo and Cado are Freeza tier, with Goku dismissing that level of power and placing it as training fodder for the boys. Goten and Trunks slamming those two down wasn't anything super impressive for Vegeta either.
