I'm gonna be honest and you are free to disagree, but I think at this point I'm so worn out with the character, Shu. Like, as a character, I think he's served enough time on the screen and needs to dial back a bit.
Don't get me wrong, I really do like Shu as a character and he's one of my higher ranked characters in my personal opinion but at this point, I just don't want him to have as much focus anymore. He's becoming the Tommy Oliver of Beyblade Burst in terms of spotlight stealing and it needs to tone down. Like, every season he appears in, they always feel the need to give him a big role in the season instead of just have him being a recurring supporting character like how Free and Lui were in Cho-Z and Superking.
Yes, I know Shu is an incredibly popular breakout character that will get fans watching the show (and he is certainly one of my more favourable characters), so they need to give him plenty of screen time but it just feels like he takes a lot of focus at the expense of other characters (who aren't the protagonists, the main antagonist or Valt).
In the first season, Shu was one of the most important characters and was the reason Valt wanted to strive to become the best. He was a mentor to pretty much every one of his friends, was one of the Spin Emperors and was a rival to the main antagonist for that season, Lui. His bey was the only one that broke too.
In
Beyblade Burst God... need I say more? He was Red Eye and the main antagonist of the series, being the only one who had his mid-evolution from Legend Spriggan to Spriggan Requiem in the God series (I mean, Valt had Strike God Valkyrie but eh... it was still God Valkyrie with a Battlizer lol).
In
Beyblade Burst Cho-Z, he was Aiga's mentor and coach (and Aiga was the main protagonist at the time) and was involved in Fubuki's development.
In
Beyblade Burst Superking, he's one of the Legendary Bladers, which is fair enough,
but then he's also Lean's coach and mentor (and Lean is one of the major characters, possibly the main antagonist). Whilst that's not inherently bad, I personally think it would be cooler if Alexander Gilten/Theodore Glass returned and mentored Lean instead to regain his former glory of having the strongest blader in his team.
I'm surprised he didn't make an appearance in GT and have him inspire Gwyn to be a blader or something.
Perhaps I'm nitpicking, but I think Shu's spotlight should be toned down a bit. Not saying he has to fade into the background, but I'd rather he was just a recurring supporting character in Superking.
Eh, I will think of something to put here...
... later ;)
