Round one team is bloodlusted.
Round two team is in character.
Raditz is in character both rounds.
Raditz hasn't shown any resistance to molecular-level attacks nor reality warping. The team can compete with him in speed and have three characters with decent levels of hax that the Saiyan doesn't have a countermeasure to defend against. As others have stated, pretty sure the team can take this with difficulty thanks to their hax.
Gremmy's reality warping has not shown to effect powerful beings in his verse (who are not shown to be reality warp resistant). Since there is verse equalization, it is a stretch to suggest that Raditz would be directly affected by Gremmy's ability.
@The_Gorosei: The way I understand Gremmy's reality warping works is that he has to be focused on his target to stay in effect and it is limited to a certain area. Not as potent as more notable reality warpers, but would be sufficient against Raditz who has no resistance to such an ability. Even factoring in verse equalization, DBZ has no equivalent ability to Gremmy's reality warping within the series thus it wouldn't be unreasonable to assume Raditz is getting effected by it.
I can see Gremmy's power working like Buu's candy beam. Even though Buu was weaker than Vegito, he was still able to turn the fused saiyan into chocolate. Raditz might be stronger than Gremmy, but the other three combatants are powerful enough to distract him while Gremmy works his hax magic.
Pre tree Madara's abilities should be OP and I beleive he's likely the strongest on the team, but if Gai could give him a bit of a beatdown Raditz could to. Juubito is just a weaker Juubidara, kenpachi has loads of power but not as much as Radditz.
Gremmy is the unknown component for me since im not current with Bleach. He has a measure of some kind of reality warping, im not sure of the extent or conditions of it, if it could indeed kill Radditz. Logically id think its inferior to ywach (the Barrigan to his Aizen if u will) and ken is dealing with it so I doubt Radditz would be overwhelmed.
Then we have to consider Radditz is not just standing still either. He could very well spam casual moonbusters which none of his oponents could withstand.
But I wanna see Madara's post tree powers. I have a feeling he might be moon level or higher with even more crazy hax.
@GeneralVan: Don't see that happening with the leaps in attributes from the HST in recent years. He could easily cream as far as high-mid tiers. But the high and top tiers combined efforts would be too much for him to deal with.
You're looking at Frieza saga level characters now who could easily cream the whole HST.
