Revamping Characters

[Wildfire the Dragon]

OK, this is about my characters I made up. I'm having a few problems with it. I made some different looks of mine for the fan fic and fun.

I made a Character from the Sonic and Spyro Series.
I also made a Koopa Troopa to sneak into Bowser' Castle.

Here are my designs

Sonic Series:
Name: (Unknown)
Species: Hedgehog
Color: White with Green Stripes on Quills
Shoes: Sonic Style with Shadow's Hovering Devices
Eyes: Green
Other: Megaman X1 Armor on arm.

Spyro Series
(Before I start this, I did a design earlier and I when I saw KT Greenstripes character Blaze, mine had the same design. I started to change it but it's very complicated. Here's some of the stuff on him

Name: (Unknown)
Scale Color: Green
Spike Color: Gold
Eye Color: Green
Horn Color: Gold
Tail: Rounded Spike (Like Spyro's)
Clothes: (Thinking)
Other: Spiked Wrist Bands

Koopa Troopa
Name: (Unknown)
Shell Color: Green
Shoe Color: Blue
Other: Sunglasses, Spiked Collar, Spike Wrist Bands, smaller version of Sonic Hair

I had a pair of pants with the legs ripped off to look like shorts, but I'm afraid of copying someone's design. He can stand on two legs just to let you know.

Problems
Sonic Fan Character: Need a Name
Spyro Fan Character: Need a Name and a different look. (Good chance I might keep the ripped up pants)
Koopa Fan Character: Need a Name

Could you please help?

I could give the Koopa Troopa a try

[Wildfire the Dragon]

Oh yeah. This is also a request section. I'm just trying to get new ideas to complete my characters. You can request if you like and try to help me.

Edit: I have another problem. I'm trying to combine my cousin's animal spirits like my Half Dragon form.
A lot will help

Roshi - White Tiger Spirit
Taoshi - Water Dragon Spirit
Loshi - Silver Wolf
Quoshi - Phoenix Spirit

What of each part of their spirits should combine?
