So I thought I had that haha moment and everything would click but it seems I'm more stuck than ever now. A little long but more insight into my process.
My first batch of characters were, dps-ish cyborg soldiers that take the front lines of the battlefield. I would provide them with weapons and shields to help them and friends in battle.
Then I made some alien bug inspired mechs...Not a lot of comments on them so I don't know how much people really liked them.
2nd batch of characters fit the theme of recon more. Giving them a companion to help in battle I thought was cool.
But after reading feedback, I felt lost because of only a few comments.
So I tried to keep things simple and here's what I got...
They're cyborg martial artist inspired by people like bruce lee, jackie chan and jet li. Besides some others being the alien/meta human or the street brawler. But all(except the alien)are the same in that there cyborgs.
Which means they need to be quick, agile, average bodies, have something robotic, light clothing and to add to the coolness, cool hair that can be simple or crazy.
I thought of the key words being robot arms martial artist or alien martial artist and these should pop up. But looking at these I feel unsure.
Do I like them? kinda
Are they simple? I like to think so.
Iconic...I don't know.
Goku from DBZ can be consider a sci-fi character. Alien ape race of people that can fight. He is simple in design but what makes you remember him if you never see the show? Hair and maybe colors? You know he is a fighter based off clothes alone. But you don't know he is a alien of comes from another planet or he can shoot ki blast like a kamehameha from a concept sheet of front and back. These little things are the ones I struggle with the most.
So Now I try again with this new female character. Giving her some kind of iconic hair(real anime like and I love it.
) with street clothes to give her the brawler feel. Simple colors to know her by and the powers to control space or something like that. Just found out that Superhuman and biopunk (among others I didn't know of) are subgenres in scifi and I wanted to explore it as not a lot of others are. Was thinking of superheroes like the ones in xmen or something like that. People are doing either cyborgs, mechs, androids like I previously did. This isn't a bad thing at all but lets try a different angle.
Simple story is that she is biologically created and has the powers of telekinesis and power over space. As a concept I might need extra sketches of abilities(which is always nice and shows me thinking of these things) I had a lot of fun with this one. It was easy to do in a way that I just thought of my favorite anime's
From the feedback and my own opinions I think my other characters are cool. But hopefully what I have now is cool and fun as well. Its geared towards young adults. biggest concern now is, is she to simple? I want her to be:
Badass
Brawler
Quick
Agile
Cool
Theme being hiphop as you can see in the clothes. It's something I see/own myself(male versions of course) I was thinking or having her arms become see through and you can see the universe in her. (best if I show than write) She's a super natural being with the powers to destroy and create in a human body. Her code name: Cosmos
It was said I should have fun and find my own shapes and stuff and I feel like I did that with this. Can I always go back and make another character or do another variation? Yes
Can I modify the story more? Yes
Sorry for the long post. Felt like I need to post something. I will go back to my other characters and see how I can change them maybe unless people like the new direction.
C&C always welcomed.
