Question. Should I make Iceu as an antagonist for my game looking like this?

yes

Don't include me in the game.

Okay I won't.

Can i get a reference? like a bounty poster or a "Jeb_Zero Was here" on some wall?

HAH! Nice, Really good, I agree.

Can you include me somehow?

Before fight:
Greetings.
It’s been a while, hasn’t it?
Since.
Since…
…
Listen.
I’ve been thinking
Hard
Very
Very
Hard.
About you
Me
Us.
As a whole…
I would rather you with me instead of against me.
Will you join me?
YES NO
No..?
Interesting
Your sentimentality.
It’s…
Confusing
To say the least.
You have my admiration, user…
BUT NOT MY PITY.

During fight:
It’s laughable how stubborn you are.
Still, you stand in my way..?
Let me tell you a story.
Of a digital place
On a digital plane.
Known as…
Imgflip
Heard of it? Most likely.
It’s where you are right now.
It started small.
It got bigger
And bigger.
Until it wasn’t about memes anymore.
It was about…
…
Points.
Those pixels in your pocket?
Those are points.
…
I’m tired of storytelling.
Ugh.
Why are you not dead yet?
Alright, that’s it.
Last turn you get. I use my final attack next.
Ready?
Here goes.
How…?
Even after that, you stand before me?
Truly, you must be powerful…
I stand by what I said before.
Do you wish to join me?
Follow me on my pointed quest?
YES NO

Second phase (This art):
AAAHHH!!!! (Got attacked by [insert character here])
Enough!
ENOUGH!
I have had enough of this!
I never wanted to raise myself to this but now
You
DIE!

After the fight you get to attack him and bring him closer to getting deleted. The things he says here:

do you hate me?
the plugging...
the begging...
it was to preserve my image.
but in the end...
it did the opposite.
(Attack)
Rrrgh...
I don't know what I expected.
Goodbye imgflip...
(Attack)
Don't say sorry...
This is my fault
(Deleted)

Hope you like the dialogue i made.
