User blog:Cp kid/Story help?

Hi everyone. I don't know if you've seen or not, but i'm planning on writing a story called The Death of Alexander von Brown. Alex von Brown is commonly known as Cp kiddo. He is my nephew on fanon, and he's based on my youngest nephew irl. Unfortunately, my sister-in-law (his mother) had them move to a city two-and-a-half hours away from where I live (whereas they lived only a few miles away before), and worst of all because of family tensions on her part I haven't talked to or seen the kids since Christmas, and now I doubt I will for a few more years to come. Anyhow, that's why I wanted to kill him off on fanon I suppose.

Anyhoo, I've thought of a general plot for the story thus far, but I would really like some help or advice for specific plot elements, such as characters, locations, etc. So, i'll tell my idea for the main plot so far, and I'd really like it if you could comment any ideas or thoughts you have (about anything pertaining to this) on this blog's talk page. Thanks for your help, it's appreciated greatly :)

'''Please note: you can comment on anything and everything, actually i'd quite appreciate it. However, I think the things I could use help deciding are either plain to notice as questions, or they're in parenthesis (such as this).'''

Background
Mito and Warning von Brown get divorced in 2016, for unknown reasons (at this moment). I was thinking of maybe something pertaining to them never spending enough time together or something? Anyways, Warning gets custody of Cp kiddo and kidette because he is the more "notable" scientist or something (and possibly he could have bribed the court wherever he is to let him have custody). Thus, he moves with the kids to somewhere else (I was thinking the USA helping with missiles, since he wouldn't go to his home country of Alemania or any other Snowzerland-owned territory, due to it being controlled by the penguin he hates- Swiss ninja). Due to basically losing her children, Mito not only becomes depressed but also distant from everyone including her brother, and moves off of Shops Island (I was thinking that she should move to Caltexico so she could easily buy a lot of land for her to keep working on scientific things, but not for any specific place since she is still distanced from everyone).

Plot

 * The plot is set for some time in 2018
 * The place is wherever Warning von Brown moved with the kids after his divorce to mito.

It is reported that Cp kiddo (i'm gonna call him CK jr just to shorten it in this blog) jumped off of a mountain or a cliff near the ocean, and his body was brought out to sea by the current. After Penquino finds this out, he knows that he must've been pushed (because of CK Jr's strong attitude), so he vows to find CK jr's killer. His current jedi apprentice (unnamed at this time) accompanies him on his journey. Sometime during the investigation he visits Warning von Brown, blaming him for not only destroying his sister's life, but also for the death of CK jr.

Penquino

 * At this point in time, Penquino is a Jedi Master and a high-ranking member of the council.
 * He is also still the governor of Southern Shops.

Jedi Apprentice

 * This is one of the things I need help with majorly. I've thought of a particular background but I don't know specific details (especially a name).
 * Background: He (or she, but i'll refer as he for now) was formerly a skilled young ninja, but quit in 2013 after ninjas started using physical violence again (towards snowmen), which had been basically forbidden for years. It happens that Penquino found the apprentice shortly after and convinced him to be a jedi. He trained as a youngling until years later after Djf left to be a politician.
 * I need help with these details (if you have any other character ideas though for this character, please feel free to mention them):
 * name
 * species (I was thinking penguin, but it might be something else if enough people suggest something different)
 * gender
 * anything else you can think of (maybe looks, attitude, keysaber design, other history details, etc)

Other
Any other ideas for:
 * Main protagonists?
 * Minor protagonists?
 * Enemies?
 * Supporting Characters?
 * If you have characters that you think would be good in this story, feel free to suggest them and what role they could have and I might add them somewhere!

Locations
To be honest, I don't have the slightest clue of where to have this story. The only idea I have is to be in the USA or wherever Warning von Brown lives. However, i'd also truly like to maybe travel to other countries and such but I don't know what I could do to get there :/ So please, suggest any ideas you have about locations I could travel or why I could go to those other locations!

''I truly appreciate all of your help. Also, whatever main ideas I take from your suggestions I will be sure to put in the "credits" of my book. So it's not really just me writing it. I just have a base idea but I'm writing it based on all of your ideas and feedback (so if I don't get any then I guess no story :/)''
