I try to hear a specific voice in my head for my OCs or any adopted OCs.

Do you hear your voice for your main OC when you read something they would say?

Of course! LuxrayBlast is my Sona. His voice wouldn't change. Only time it would apply is when saying "Shinx!" to be cute.

That makes sense. I think all my sonas have a differnet voice. Snow's voice is kinda obvious. He is my normal voice.

Here examples:

Grousiin (Torterra)- He has a very deep voice, but, rarely sounds intimidating and commanding, just sounds tired & groggy. However, when mad, his voice BOOMS. If in tears, he his voice becomes softer and fearful, with the sound of choking back tears just to speak.

Demetrius (Dialucario)- His voice is kinda like the voice of Lucario in SSBB, SSB4 & SSBU.

Swez (Floatzel)- He has a bouncy, but, calm voice. Think like a laidback Surfer.

Their voices also are meant to somewhat represent their in game cries.

If you wanna do this with Cobalt

To me, his voice would be like bit robotic with emotion as he is more flesh then metal

I'd imagine his voice gets a little garbled when he gets very emotional

I can see/hear that. So a bit like Rambley?
