Ok, my brothers and I came up with these great ideas for Hales (Warning: not 100% thought given). I don't want to overbear anyone, so I'll only give a few.
Black Doom (Shadow the Hedgehog)
sprite: alien
health: high
speed: below averageslow
weapon: swift strike
weapon description: Black Doom slashes out at the opponent with a purple trail
rage: Chaos Control
rage description: "time slows" by speeding up Black Doom and increasing attack rate
color: red and black
I don't know the obituaries, voice, and I couldn't decide on a theme
Meta Knight & Galacta Knight
sprite: I don't know yet but there is a meta knight already made from Kirby's adventure
health: (Meta): below average (Galacta): above average
speed: Both are fast in speed
weapon: (Meta): Galaxia (Galacta): beam lance
weapon description: They slash out like the flame sword wihout the flame(more like Gilgamesh)
rage: (Meta): Mach Tornado (Galacta): Sword Beam
rage description: (Meta): Meta knight places tornado holds around him and heals up to 1000 hp (Galacta): Galacta Knight reaches out with the laser from his sword(Thundera Claw) long recharge
theme: Galacta Knight theme from Kirby's return to dream land
I don't know if I should do voice because Galacta Knight doesn't speak
There are plenty more, but I don't want to do too many at once.
