Well, maybe the theme is supposed to be the Guan Yu's and Zhang Fei's theme fighting LuBu, we can hear the dw4 Lu Bu for a moment, indicating that Lu Bu still is the demon on the battlefield.
It's fine. But I always feel like the best part of the theme is the chorus part, yknow that one part... Anyways, In this version I feel like this kinda keeps at such a constant beat, that the most recognizable part becomes kinda glossed over and doesn't stand out from the rest of the song As it does in nearly every other version. I would argue that 4 and 7 had the best versions. 4 Had such a pure feel to it that to me, I believe it set the standard for Lu Bu's theme song. As for Dynasty Warriors 7, I felt so so different but also gave such a rush of nostalgia. It felt like you hadn't played Dynasty Warriors in such a long time and that theme just brought you back.
This theme was used SO WELL in the Netflix film, whether you love or hate that particular adaptation, the scene where they fought Lu Bu's army on the bridge was WONDERFUL!
@@xlubu-q8 Yes. It's a movie though, and only covers the Yellow Turban Rebellion, Dong Zhuo overtaking the capital and becoming a tyrant, and the Battle of Hu Lao pass with some minor events in between
@@donaldlayton437 not much, i guess at least for recognizing that you defeat lu bu maybe at normal lvl. I mean that's the far i can go lol back there times, even normal lvl i cant beat lu bu lol like the saying "do not pursue lu bu"....
............................ Okay, I admit it. DW9's score is friggin' amazing and this rendition of Lu Bu's theme is in the running for the best Lu Bu theme ever done, along with DW4 and DW8.
I never thought someone could have an objectively bad taste, but I stand corrected. This weird rock ballad has nothing to do with Lu Bu, but the name and some riffs.
Playing since 3. Favorite rendition from my stand point. I'd urge most people here to give the game a go again. You may be surprised with what has happened since you've been on. (Run on the new difficulty if you got the balls(or ovaries))
Same here...no matter how much my inner child wants to hold on to the DW4 version, DW9's rendition is just pure perfection of everything that came before
Lu Bu will be a Super Heavyweight with long disjoints, and adding the Musou Gauge for just the sauce of it, now im not sure about the recovery part since DW doesnt involve much aerial combats
You keep sending them!!! I'll keep KNOCKING THEM DOWN!! 1st theme of his where he is the hero... Honestly... Hes become that badass of a villain all these years that Koei finally turned him into like... An anti-Hero... Not a full blown hero I guess... But still
Only we could save his history dying in past...real history beat ass cao cao forces..like we borrow modern armor n his new weapon halbert like this lu bu game do...n train him more muscular learn art war!!
I wish that it was possible for someone to make a Lu Bu Theme Medley that transitions from each Lu Bu Theme, and since they mostly sound the same, it wouldn't be too hard to pull off
Bro is holding against Zhang Fei with just one hand holding the Halberd. Lu Bu is ridiculous strong if Cao Cao had kept him in his army he could totally annihilate Wu and Shu and prevent Sima Yi from capturing Wei. and if Cao Cao die Lu Bu could take over the Wei make it the Lu dynasty.
xAlpha Wolfzx Yeah... past DW Games had a decent and good themes.Lu Bu’s theme not even close to the other past games also Warrior Orochi has way better Lu Bu themes but Lu Bu was just not as scary in Warrior Orochi compared to other characters from the game
@J announced long ago, but it should already be out by last year. except it hasn't because there has been no word of it ever releasing since the trailer popped out
Warlight yea...well hong kong make that movie really arkward 1 guan like short a little bit and little skinny 2 lu bu same but's he's horse is red hare but is a white horse 3 sun jian is really like 23 years old totally young and in the game he's 67 years old
Used to be the games theme and lu bu's theme were one of the same back in DW4, just slightly different. So if your an OG player, this is more like the theme of the franchise then just lu bu.
To everyone who says DW4 theme was the best... was it really though? Like honest question. Because to me it just seems like a remix of the game's main theme.
This is badass music that I ever and this song is for who badass people like riding a muscle car jumping from cliff then using a machine gun or kill the enemy by using a knife from the fence then strike
If you think about it,Lu Bu is WAYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY stronger than Goku. Lu Bu kills 1,000 people every day.There are 365 days in a year, meaning he kills 365,000 people in a year.He was popular(In Games)Between Hulao Gate and his Death at Xiapi. Across those 7 years,HE HAS KILLED 2,555,000 PEOPLE. How many people has Goku Killed?
@@TheSomeone499 True, Freeza possibly has more kills than Goku, considering he has wiped out entire planets worth of life. Though Goku bested him in the end, though not sure about Beerus as I haven't followed dragon ball after the multiverse tournament Arc.

This is great but... Idk I feel like they added a bit too much to where it mostly doesn't even sound like Lubu's theme until you get to the obviously recognizable parts.
This Lubu's theme sounds more Heroic then the others
Same
same
It's the beginning chord progression before it goes into the familiar guitar track. It's like a grand opening ceremony.
@@mirror2922 the beginning chord progression is actually the Dynasty Warriors main theme
@@0flame01 ahhhh its pretty clever that they repurposed it for an epic start to the piece then.
Lu Bu's theme in DW9 makes him more like a superhero than a demon on the battlefield imo
Hahahaha, yeah.
I hear Masa, The composer for Dynasty Warriors is retiring. If that's the case, This version of Lu Bu's theme almost sounds like a farewell version
in his eyes he is the superhero though
Well, maybe the theme is supposed to be the Guan Yu's and Zhang Fei's theme fighting LuBu, we can hear the dw4 Lu Bu for a moment, indicating that Lu Bu still is the demon on the battlefield.
No matter your opinion about the game, we can all say that this version of Lu Bu's theme is amazing
yeah bro, this theme is awesome
Lubu's theme is always the best part of any DW game, imo
@@donaldlayton437 so true, every remixes of Lu Bu's theme are just godlike

Changing formation has never felt more intense, makes me think back to the Red Cliff days...
3 rules in Dynasty Warriors
- do not pursue Lu Bu
- do not fight Lu Bu alone
- do not kill Diao Chan
I remember playing Dynasty Warriors 2 and thought Lu Bu was just another ordinary general. I paid dearly for my mistakes...
I managed to defeat Lubu alone. Of course, it was in Easy and my character lvl was in the teens so does that count?
@@donaldlayton437 not much, i guess at least for recognizing that you defeat lu bu maybe at normal lvl. I mean that's the far i can go lol back there times, even normal lvl i cant beat lu bu lol like the saying "do not pursue lu bu"....
I once beat diao chan first, then the game announces "Lu Bu is enraged!" Lol it got some reddies around lu bu after that. Really mad 😂
@@mohamadfaizzudin6869 I think killing Diao Chan first makes Lu Bu tougher to beat. It's been a long time since I played so I could be wrong.
“It’s Lu Bu! Lu Bu has come to destroy us!”
👿👿👿👿👿👿👿👿👿👿👿👿👿
Quote "the private" before one of them unleashes the buuuuu~~~ sound when struck down by Lu Bu
I first encountered Lu Bu in Dynasty Warriors Advance for the GBA, and man his early renditions are indeed demons on the battlefield.
............................ Okay, I admit it. DW9's score is friggin' amazing and this rendition of Lu Bu's theme is in the running for the best Lu Bu theme ever done, along with DW4 and DW8.
I never thought someone could have an objectively bad taste, but I stand corrected. This weird rock ballad has nothing to do with Lu Bu, but the name and some riffs.
Dont listen to that guy, Aussie. The soundtrack for DW9 is really freaking cool.
meh u can't compare this to dw4/8 theme... srsly... weak ass drums
@@ErdeZ You know you a dumbass when you mistake objective for subjective.
@@RiveriaTV It's not all about the drums tho
Usually I'm one for advocating themes that fit the character more, but this has to be the best version of this theme out of context.

3, 5 & 7 are my favorites so far.
*what about 4*
I love dw 6
4, 5, 6, 7, 8 for me
"ALRIGHT! NOW I'M GONNA START SHATTERING SKULLS!" - Lu bu (Dynasty warriors 5)
"lu bu among men red hare among horses thats him!"
that pic i think i know that scene
that saying gets even better when you hear it with the chinese dubs. the mobs sound like they just shat their collective pants
If Koei Tecmo gets a rep in Smash this song needs to be added
And the result is another trailer where the guest absolutely REKS mario
Zhao yun... because if it's Lu Bu may he have mercy on them LOL
Lu Bu will be a Super Heavyweight with long disjoints, and adding the Musou Gauge for just the sauce of it, now im not sure about the recovery part since DW doesnt involve much aerial combats
@@ssctiyo4735 He could use Red Hare and jump from him
The most iconic hero and his own theme! 👍
Lu bu is the best character there is in this game no dought. Like they say "lu bu among men red hare among horses"
7 and 4 are still probably my favorites. But this is pretty dope
same, I love 7 theme
You keep sending them!!!
I'll keep KNOCKING THEM DOWN!!
1st theme of his where he is the hero... Honestly... Hes become that badass of a villain all these years that Koei finally turned him into like... An anti-Hero... Not a full blown hero I guess... But still
2:04 - 3:00 listen and close your eyes,now imagine you are lu bu and rampaging on the battlefield. epic
"GhahahahahahahahHAHAHAHAA"
That as well as doing his rage musou where I smash a poor soldier’s head then drag him while charging through thousands of enemies
Sounds like Lu Bu's last battle
Yeah, you right
exactamente eso!
Xia Pi Intensifies....
Only we could save his history dying in past...real history beat ass cao cao forces..like we borrow modern armor n his new weapon halbert like this lu bu game do...n train him more muscular learn art war!!
ONG
Even If Lu Bu had a regular 9 to 5 Job, his life would be more interesting with this theme.
I would think he'd be a pro wrestler in WWE. Just saying.
@@donaldlayton437 He'd be top star in a week. 6'10" according to the wiki, ripped af, athletic, and can toss men around barehanded? I'd watch that.
I wish that it was possible for someone to make a Lu Bu Theme Medley that transitions from each Lu Bu Theme, and since they mostly sound the same, it wouldn't be too hard to pull off
All the way from 3 to 9, this theme will always give goosebumps to me p
Personally..i love it...most likely more because of good music...maybe it really isn't the best theme for Lu Bu...but damn is it epic XD
Run It's Lu Bu. Run from his chokeslam.
I love the intro to this 😍😍
"Turn back, for only death awaits you beyond this point."
Bro is holding against Zhang Fei with just one hand holding the Halberd. Lu Bu is ridiculous strong if Cao Cao had kept him in his army he could totally annihilate Wu and Shu and prevent Sima Yi from capturing Wei. and if Cao Cao die Lu Bu could take over the Wei make it the Lu dynasty.
The Greatest...🙏🏽
"'Musou' is the destiny of God.."
This doesn’t sound aggressive enough to be Lu Bus theme it’s very light hearted and heroic
xAlpha Wolfzx Yeah... past DW Games had a decent and good themes.Lu Bu’s theme not even close to the other past games also Warrior Orochi has way better Lu Bu themes but Lu Bu was just not as scary in Warrior Orochi compared to other characters from the game
Well here’s the good news,Miss Diao Chan is still safe.
Nope song wanna lu bu keep on pressure attack on n save day beat everyone's..
6th version of Lu Bu's theme have more muscle and aggressive.
They used this on the new Dynasty Warriors movie trailer!
speaking of which, when's that coming out? haven't heard a lick since the trailer came out

3 sun jian is really like 23 years old totally young and in the game he's 67 years old

And still the best Lu Bu's theme is the one from Dynasty Warriors 4.
yes, 4 is the most classic one.

Of course.

But anyone can tell me who is the creator all of guitar part ?
it's listed as MASA in koei tecmo's spotify

imagine how much worse the game is without the weight of this theme's balls lifting it up from total disaster
I appreciate the experimentation with open world, but... yeah, agreed.

Lu Bu (DW) vs Justice League (DCEU)
This is not as good as the other themes for DW.But personally DW4 Lu Bu theme was the best and also Warrior Orochi has a better theme then this.
3 and 4 are the best
Lu Bu:what is strategy?
I still prefer DW 8 version tho

always scared me to face him

Sounds like hero is coming in the battle then Demon.
His best theme is in DW4 for ever!
@Sima Yi totally agree is soo slow for my taste i like more the themes of dw 7 and 8 that's ones are the best for me

Yeah it's good song but when you compare it to more fitting one like dw4,6,7,8 it feels little weird
@Unknown User 5 is special not weird,it's kinda calm compared to other theme but still love it
If only the rest of this game wasn't a flaming pile of Red Hare crap.
Hmm.. For some reason lu bu theme not as aggressive as the past games, still quite good tho!
Nice theme, But I prefer the theme from Warriors Orochi.
Um... when exactly does this play? I never hear ANY real music... only seeing some real annoying grafic bugs lately XD
Shadowfang hulao gate? Lol
Yeah the game somehow bugged my music down to 0%....
lmao youre not the only one, the game doesnt play the song sometimes when you encounter Lubu.
