WCI's characters that still don't show their true colors

Let us focus on characters in WCI arc that still don't show their true colors yet..
As we know that WCI arc will reach it climax soon..
And yet there are some characters that left without information on their strength or ability yet..
Or Oda just adding them so we can see that Big Mom got diversity in her army..
As Oda did mention that Big Mom want to create a place ideal for all races..

So..
Let talk more on the WCI characters..
For me all the character that I listed here still not perform well or still not their true colors..
The characters are:
a) Big Mom Pirates
- Most of Big Mom Pirates that I listed down below are not yet shown their full potential via fighting skill.. I would like to see their capability in fighting more.. Do they got DF ability in their sleeves..
i) 'Sweeper' Bobbin
- As Bishop for Big Mom Pirates, Bobbin left us wondering bout his true potential..   
ii) Tamago
- After the fight with Pedro, Tamago that fully awaken his Chicken DF power seem not shown us anything about his last stage.. As the knight for Big Mom Pirates, he might be in certain level of power.. right?
iii) Charlotte Smoothie
- As Sweet Commander for Big Mom Pirates, we still don't know the exact strength of Smoothie.. Instead of knowing her DF ability that can pour out the liquid from her opponent.. What else she can do with her DF power..
iv) Charlotte Compote
- As 1st daughter of Big Mom, Compote don't do anything yet.. She don't fight at the roof top too.. Do Compote will participate later on in Chocolatown..?
v) Charlotte Daifuku
- As the third son of Big Mom, Daifuku not yet fully shown us his capability in fighting.. Although we knew about his DF ability as he rubs his body.. Some kind of genie will come out and fight.. What more does he got rather than that..?
vi) Charlotte Oven
- As the fourth son of Big Mom, Oven also not yet fully shown his capability in fighting.. His DF ability that can make anything touched him become crispy due to the heat.. What else he can do with his DF ability..?
vii) Charlotte Mont D'Or
- As the one who makes Luffy & Nami captured earlier in this WCI arc, Mont D'Or who has the DF ability to capture his opponent in the book now control the TOT battle ships.. Do we can see he in action somewhere later..?
viii) Charlotte Amande
- The girl with sword still don't give a good performance yet.. What she had in her sleeve..?
ix) Charlotte Galette
- The one who fight with Nami in the past alongside Amande and Mont D'Or also not perform yet.. Hope that she will appear later..
x) Charlotte Opera
- Opera maybe has grudge toward Jimbei for punching him at Big Mom Library.. So I do hope that Opera will shown his capability in fighting in near future..
xi) Randolph
- This rabbit is missing in action.. I do hope he will appear again..

b) Underworld Emperors
- 6 Underworld Emperors come to Big Mom's Tea Party.. But none of them shown their strength and power yet.. Although one of them (Stussy) turn to be CP0 agent.. We all know that CP0 is most powerful team after CP9.. Will they help Big Mom later..?
i) Du Feld
ii) Stussy
iii) Drug Peclo
iv) Morgans
v) Giberson
vi) Umit

c) Others
- I do hope all four characters (except Incarnation) that I mention below will show their best action later in Chocolatown.. Although maybe Vito and Gotti are now with Capone trying to escape from WCI.. Who knew that Capone will change his mind and want to help or save his wife, Chiffon at Chocolatown.. I would like to see Pound will faced Big Mom to save his daughter, Chiffon too.. I do hope Sun Pirates are still there in WCI.. Or maybe they waiting the signal to cross Big Mom's territory at Chocolatown (as Chocolatown is the safest route to escape).. Could Aladdin help Jimbei in future episodes..?
i) Pound
ii) Vito
iii) Gotti
iv) Aladdin
v) Incarnation
- About Incarnations.. Big Mom creates them to help her to collect lifespan.. Maybe Incarnations also can implant that lifespan (soul) into objects and animal.. Or maybe Incarnation also can put the soul back to where it belong.. I doubt that Incarnation will revive back Charlotte Muscato (one of Big Mom's son) as Big Mom pull his lifespan out earlier in WCI arc.. I create one post on Incarnation that similar with Gecko Moriah's Doppelman.. (Search and read that post)

- Just one thing to add here.. If Chocolatown is the safest route to escape.. Maybe that's true.. That's why Lola can easily left WCI so that she can find her true love.. We all knew that Luffy and others comes to WCI with Pekoms.. They arrived in Cacao Island (Chocolatown) first.. So this mean the route to escape is from Cacao Island..

What do you think of this..?
Please comment below if you got anything to add.. ^^
