They can take rounds 3,4 and 5 but I don't see them taking 6-10 or 2, probably not 1 either. Starrk and Ulquiorra could level the field to a crazy degree. Lanza del Rallempago + wolves + cero metraletta? I could only see Black Star barely surviving a taste of that and even then he can't take them out alone. Dangai Ichigo is just too powerful all around. Naruto is pretty bad too. If he starts off with using his 5 minute Kyubi mode he could spam mountain+ peel biju dama. Could go either way depending on scenario but a serious Naruto could beat them, especially Natsu even if he weren't serious. In round 2, current Ichigo's power is unknown, but we know it is several times more powerful than he's ever been so just imagine several times Dangai form. Shunsui even said he could be too strong for the Human world to withstand just by being there. Melo Cola Toriko wasn't nearly what he is now, but he could easily dispatch the 3 1 on 1. If he took out Black Star first, Liffy wouldn't be a big problem and Natsu isn't worth much mention. Teen Goku too much just all around, not much explaining is needed I don't think. Round 10: They get the first 3 hits but only Black Star's blades could do something. That's actually a problem to be honest. If Vegeta just stands there and lets them attack him then Black Sar could impale him through the heart and they could potentially actually win against what should be the strongest character in the gauntlet.
