[7.0] "OSKAR is a very good big man. It's a little early into his career to tell how he's gonna fair in the long run but thus far he's a darn good tag team performer alongside Yuto-Ice. Whether the Knock Out Brothers remain a dedicated tandem or split into singles acts is gonna be a big driving question for his career - the history of professional wrestling is littered with the bones of big men bookers thought were gonna be big stars when given a solo push."
[7.0] "So far he has potential. I feel that he could very well be a great monster heel in the next year if he manages to improve and impress consistently. He performed really well against Taichi/Ishii and his singles match against Umino was good too."
[6.0] "A giant in the ring, especially for NJPW - and a solid worker with a lot of upside. He stands out as the weaker half of the Knockout Brothers compared to Yuto Nakashima, but Oskar is already showing his potential, he just needs ring time to put all the pieces together."
[8.0] "A prodigious talent. I am firmly of the belief that he will be one of the best wrestlers that Europe will ever produce. On the road to being as good as WALTER."
[7.0] "A big man among the lions is exactly a huge turning point. Oskar might still be green, but given the time, just like the others, will prove to be a hell of a german monster. Can speak english and japanese perfectly, so he can go anywhere to polish his skills when the time comes."
[7.0] "This guy has a lot of potential. He moves very well for his size. Something about him says sky-high potential to me, but I don't know why exactly. He seems to have a natural understanding of the wrestling ring."
[7.0] "What an impressive looking dude, has a look you cannot teach. Moves well for a man of his size and has a good intensity. Lots of easy comparisons to Gunther and we'll have to wait to see if he can be 'the next gunther' but right now it looks like he has all the tools to do it. Yes he doesn't have a strong 'personality, signature or finisher' yet but he's a young lion... that's the point. I look forward to seeing him develop and I will be following his excursion whenever and wherever it may be."
[0.0] "Let me explain... No personality, no signature/ finisher, no reason to be his fan, no way he 'll be ever a medium wrestler. Must I continue? DUD"
[7.0] "Leube is passionate and powerful, everything NJPW needs in a rookie his size. This dude definitely needs a little bit of work, but after that, I'm thinking United Empire as his destination in a stable."
[7.0] "One look at this dude and I think about WALTER. He has the look, and already has a feel about him right now. NJPW may have found their own version of WALTER right here. I am interested to see if he puts on a lot more size, and if he does study what makes WALTER who and what he is, and incorporates that into himself to mold himself into an eerily similar type of monster."
[7.0] "One of NJPW's most intriguing Young Lions. His size alone would put him in line for good things after his excursion, as there is always a place for an imposing gaijin. But he's much more than just a large frame, he immediately jumps out to you because of his intense fire and passion, he's not afraid of any spotlight put on him. He's fairly crisp in the ring and moves really swiftly for his size. He's a good seller as well, Being a Young Lion there isn't much else to write home about with Oskar yet but I expect a very solid career ahead of him as a heavyweight gaijin beast. Given his heritage he seems a perfect fit for United Empire after excursion."
[7.0] "Pour certaines raisons j'ai le sentiment que Oskar peut devenir un super bon catcheur une fois qu'il aura une gimmick. Une chose est sûre, il marque les esprits dans les matchs et se met vite en avant."
[7.0] "Saw him wrestle for the first time at Historic X-Overand all I have to say is that he will certainly be one of the best heavyweights in NJPW. For a rookie he is pretty much consistent and very energic despite his size. His fighting style powerfully reminds me of WALTER (Gunther) as he resembles the latter's in-ring techniques and charisma. He has a very bright future."
