Aikatsu! (English dub)

If Aikatsu! and Aikatsu Stars! had an English dub, it would air on Animax (in the Americas especially the United States) Cartoon Network (in Europe especially England), Disney Channel (in Asia-Oceania especially Australia), and Nickelodeon (in Africa especially South Africa).

It's a fifty-fifty chance that they'll keep Aikatus as a title.

Plot
There will be minor changes with the plot here and there. Ichigo/Akari Gen will most likely start on season two (Keeping Animation quality in mind). A lot would be cut but could possibly be explained throughout the season.
 * Aikatsu!

Instead of Allison (Aoi) and Rachel (Ran), introducing themselves. The first episode would start with Casey Henson (Ichigo Hoshimiya), Though not on screen, talking about them before the Audience learns that she's Overseas. That way, the audience is introduced to the protagonist instead of having her thrown at us later in.

Some character's ages could change. I think this change would be around 'Sexy' based Idols if they don't change Typings.

Ex. Rachel (Ran) would be one or two years older than Allison (Aoi) and Casey (Ichigo). Jennifer (Juri) would be one or two years older than Annie (Akari), Savannah (Sumire), and Helen (Hinaki).

Much like the in the first series, Sexy type Idols might age up. The only Expectation would be Mackenzie (Mahiru) and Katie (Koharu). Because of that, 'Sexy' might change into 'Elegant'
 * Aikastu Stars!

Any mention of Amy (Ako) having a crush on Samuel (Subaru) will be removed. Instead, she will be a fangirl of all of the members of M4.
 * 1) However, signs of Samuel (Subaru) having feelings for Emily (Yume) will be kept.

Songs
Songs that don't have an instrumental will probably be replaced with originals. The songs that do have an Instrumental will most likely get a name change, only a few of them though and they'll be minor changes.

Name Changes:

(Aikatsu)Kira Power - Star Power

(Aikatsu Stars) Aikatsu Step - Idol Step

(Aikatsu Stars) TSU・BO・MI ~To The Vivid Future~ - Vivid Future

(Aikatsu Friends) Let's A · I · K · A · T · S · U Together! - Let's be F · R · I · E · N · D · S Together!
