Jericho was the first ever Undisputed WWE Champion in WWE, defeating both The Rock and Stone Cold on the same night, and he holds the record for most Intercontinental Title wins at 9. WWE is a mixture of wrestling, grappling and striking, which is the exact same thing as UFC, so home field advantage, as well as arguing that UFC is a bit harder than WWE isn't a good argument. If anything, the 2 fighting styles are dead even in almost any scenario you put them in.
Jericho has gone up against the likes of The Undertaker, who is considered
the greatest pure striker in Sports Entertainment history. Even the likes of Kurt Angle was scared to take a punch from him.
If ya don't know Kurt Angle, he's notorious for winning a gold medal with a broken neck, who
is this skilled, and was named the
greatest shoot wrestler ever.
Jericho has not only gone up against The Undertaker (and is perfectly capable of harming him), he's also able to fight on par with people who has beaten Kurt Angle on two occasions, that being John Cena, who was able to beat Kurt Angle
on two different occasions.
Jericho is able to fight on par with Cena.
Chris Jericho defeated
Dolph Ziggler. Ziggler has a great amateur wrestling background. Ziggler set the record for most pins in St. Edward High School with
82 pins. When he was a wrestlers at Kent State University, he at one point, held the record for most career wins in the team's history, earning
121 wins (the record was soon broken, but this still says a lot for how skilled Jericho is).
Not to mention that Jericho has over 30 years of experience wrestling, and has competed in over 2000 matches in his career.
Tsukasa has Class 25 LS, while Jericho is only Class 5, so you'd assume that Jericho won't be able to put Tsukasa in a wrestling hold here, right?
Wrong. Jericho has put wrestlers with Class 25 LS in holds (
Great Khali,
The Undertaker,
John Cena, etc.), so higher LS won't play a factor here.
Besides, Jericho is used to having the Skill, Power, LS, Experience, and even Speed disadvantage in a wrestling match, and since
most of the advantages Tsukasa has in this fight are either too small to make a difference, or don't play a huge factor in this fight, Jericho will have no problem finding ways around Tsukasa's advantages.
Plus, WWE has had many wrestlers who have UFC experience (Brock Lesnar, Shayna Baszler, Ronda Rousey, etc.), so facing a UFC fighter won't be anything new to the WWE verse.
Jericho's main problem is Tsukasa's weaponry, which will give him a hefty range advantage. Not overwhelming, but enough to give Jericho a tough time. Jericho just needs to pick his spots correctly, which he is more than capable of doing.
