My vote goes either to big bro Gora or to Yumoto/Mr. Tawarayama, maybe with a mention of Taishi. Gora for all the wood chopping, he sure has the muscles, plus he was the sole hero of his show (WITH A BATTLE AXE) and then for CIDE 2 it was necessary to have a team of five. Yumoto/Mr. Tawarayama because of Wombat. If we assume Wombat is similar enough to Earth wombats, wikipedia says these weigh between 20 and 35 kg (44 and 77 lb) and neither of the two seems to have ANY problems with carrying and swinging Wombat around. Granted, Mr. Tawarayama is, uh, life-deprived so that's not exactly him but still. Taishi for his past delinquent days and the fights he surely got into, nothing more to add here. Loose idea thrown in at the end because why not, we don't know much about where exactly the Beppu twins lived in space. Maybe it was a place with vastly different gravity, then possibly they would've also developed considerable strength by Earth standards just to move around freely, but again, we don't know and they don't display that clearly. Cheers! (or did I misunderstand and you meant power-wise? D:)
You answered me perfectly!
Im debating on making a video or just an analysis on each boy in Boueibu to try to determine who's the strongest/most powerful.
To which I agree with you, Gora can easily be seen as the strongest as he worked alone. Wombat thinks highly of Yumoto (we see this a lot in novel one, where he feels Yumoto is on the same level as the God who created Love, which Gora doesn't like).
The twins are really strong with their attacks as well, which we see in the s2 finale.
I've never really watched HK, but from what I've seen of him, it makes complete sense of what you've said
