Magolor's true nature is still up for guesses. Noone really knows if he's a good guy or a bad guy, if you get my drift.
Also, Knuckle Joe's a literal goomba. Literally everything our deetractors think we are. That is Knuckle Joe in a nutshell.
(I also have a deep hatred for Knuckle Joe and everything he stands for, dunno why. )
He built Kirby an amusement park to atone for his past mistakes. I think that at least puts him out of "bad guy" territory.
You're argument against Knuckle Joe is very clearly biased, so I won't even bother.
Nontheless, he's still probably the most noteworthy Kirby character besides the quadrio and Dark Matter. The fact that he made it into Brawl as an Assist Trophy means that he has some degree of notability. Plus, he Shoryukens people! He's like Ryu+.
Well lets look at what Joe is packing. We can't really make any real statements otherwise. Thus, I'll do an analysis based on his appearances. Bare in mind, this is going to be DLC for smash.. and PAID DLC at that. Nintendo would more than likely be against the team producing a character that will end up not selling well. (Not to mention the waste of man hours it would be designing them in the first place). I will be putting on my logic cap for this, and think from a logical view.
"
Kirby Super Star and Kirby Super Star Ultra
Knuckle Joe is an uncommon enemy in this game, and he appears as the only
regular enemy in the game that gives the
Fighter ability. As an enemy, Knuckle Joe has several attacks. He may unleash a flurry of Vulcan Jabs, charge up and launch a Smash Punch, or dash forward with three swift punches. If Kirby is above Knuckle Joe, the enemy may jump upward with a Rising Break in an attempt to hit Kirby. As a Helper, Knuckle Joe can use all of the same techniques as Fighter Kirby can, except for Judo Throw. He can also perform Smash Punch underwater, albeit with a much shorter range. A Knuckle Joe with a red outfit appears in
Helper to Hero.
Kirby's Super Star Stacker
Knuckle Joe fights Kirby over a star piece in this game. He first beats up Kirby and his friends before the match begins. After being defeated, Knuckle Joe is carted off in bandages by
Waddle Dee.
Kirby's Return to Dream Land
In this game, Knuckle Joe behaves like he does in
Kirby Super Star, and is a very uncommon enemy, only appearing in a few levels. Like in
Kirby Super Star, Knuckle Joe gives the
Fighter ability.
Kirby's Dream Collection: Special Edition
Knuckle Joe appears in the New
Challenge Stages in
Kirby's Dream Collection: Special Edition as well. He appears in the Fighter Combat Chamber.
Kirby: Triple Deluxe
Knuckle Joe appears in this game, sporting all the attacks he had in
Kirby's Return to Dream Land and
Kirby's Dream Collection: Special Edition. Knuckle Joe can leap from the background to the foreground (or vice-versa)."
So let me do an analysis on him now that we have this information...
Moveset pool: This is obviously present due to his attacks. I mean he is pretty much the Fighter ability.
Role: Here is where it starts getting iffy.. So far, he has only really appeared as an enemy. (Save for the helper mechanic, where I guess he did "technically" help Kirby, and was controllable by a second player.... but even then, so were a handful of other enemies in those games.) A bit lower than Bandana Dee who has risen for the stars. Especially ironic since he technically debuted in Super star as well as Joe XD
Relevance in the series: While he does appear consistently as an enemy throughout the series, his role still leaves less to be desired..
Overview: Could have a good moveset pool, however he is still an enemy.. one that hasn't really gone beyond simple helper status...
To me this doesn't really stack up well when you consider the competition, which at this point is limited to Bandana Dee, Magolor, and Dark Matter.
I'll do an analysis for these guys too.
Bandana Dee
Moveset pool: Very good. With his trusty spear and cool moves, he could definitely add a fresh style to the kirby line up.
Role: Very good considering his early days as a common arena foe, and the fact he has risen to playable status.
Relevance: Very much so. Appears frequently in recent titles, and have a good, often up front role. (Being supporting/multiplayer)
Dark Matter
Moveset pool: Moderate. Movesets could be pulled from a few of it's boss battles, and from various abilities dark matter has been shown to possess. (Couldn't one instance shoot lightning from it's eye?)
Role: Major. Key threat in Dreamland 2- Kirby 64.
Relevance: Though mostly appearing in minor roles in recent titles, it's influence in the series is still present. Many fans will recognize them.
Magolor
Moveset pool: Magic. Nuff said XD. We don't really have a lot to go on yet, but he seems like he would be a magic based fighter.
Role: Started out as a Villain, but ended up sticking around and seems to be becoming a recurring character. (Surprising since most true villains in the series end up dieing a horrible death when they fight kirby.. lolz)
Relevance: Can't really be judged yet since he is still young. Younger than BDee thats for sure.
