Let’s see:
-Pinkie Pie:
She had a “difficult childhood” living on a stone farm, with a family that loved her very much.
-She makes friends very easily, although there are also ponies that feel that sometimes she is annoying.
-Live in an (almost) peaceful time
-It seems that she suffers from possible personality disorders, depending on her mood. (Although it is not “confirmed”)
-Pinkie Pie is a baker and excellent at party planning. (big parties)

Izzy:
-She had a difficult childhood, and it seems that she has no family (possibly cared for and educated only by Alphabittle).
-She didn’t make friends easily, in fact it was impossible for her to make friends, even with her cheerful and optimistic demeanor. (until she met Sunny and the others)
-She lives in a time that is not peaceful.
-And although sometimes she looks nervous, afraid and even depressed, she has a more stable mind than Pinkie Pie, and so far she has known how to recover (of course her friends obviously helped, but the Mane 6 also helped Pinkie Pie).
-Izzy uses more “recycled material” to make her inventions.
-Izzy throws good parties, but on a moderate scale. (that’s how I see it)

Hmm, honestly, I don’t see Izzy as a Pinkie Pie copy or an improvement, but rather as a character who will leave her mark (XD) on the franchise.

Discord (Billy Butcher): Oi.

Funny enough, Izzy’s VA Ana Sani plays Anika who is a member of Vought International’s Crime Analytics.

I see I’ve found a kindred soul (and this is coming from someone who had Pinkie as his second favorite Mane Six throughout pretty much the entire run of FiM! - that’s just how much I love Izzy)

Yes I have. I can see she’s somewhat changed from A New Generation there and that she can be an annoyance to her friends sometimes, but before these episodes end she usually explains why she acts that way, if not you can at least see her feeling bad and trying to make amends in some way, which makes her relatable and charming in her own way there.

She’s also shown to care a lot for her friends (and other ponies) and seeing them happy by helping or making stuff for them and not just relying on parties or being random. The focus on her unicycling is interesting and so is her dynamic with Posey lol. She also has genuinely funny lines, her voice is much more pleasant and she doesn’t screams all the time like Pinkie usually did, especially in later seasons.

There’s more reasons I could give, but overall Izzy does feel like a Pinkie Pie type of character done right.

@kitezune
I disagree, have you seen her in Tell Your Tale?

The series is still new you know that, so we need to wait.

Intresting

That feeling you get when a Harley blows by you on the road and you never even saw it coming… That was Pinkie Pie. Thankfully, Izzy is not a Harley.

Honestly, Pinkie Pie could have a personality disorder, or just get deeply depressed (or let her emotions go to the extreme) when none of her friends agree with some idea or thing she loves (perhaps because she wants to fit in) ,however Izzy has more optimism and doesn’t let bad reviews get her down.

Also, Izzy has lived in a town where she never got any friends, for many years… I feel that Pinkie Pie would not have liked that. Sometimes I felt that Pinkie Pie had an obligation to smile (sometimes), but with Izzy, I don’t feel that, she smiles because she wants to know and experience all things.

So it’s true Izzy is an improvement on Pinkie Pie.

Yep, already a big improvement over Pinkie tbh

Well … it’s true

At least Pinkie has a consistent VA and a husband and daughter at series end. So point goes to her.

Upgrade but cute annoying

Supremizzy!

I don’t know, I can see both getting along very well honestly

Izzy’s not wrong

She can do magic so yes a Upgrade
