lineless version (cause it's kinda cool to me) and original sketch:

no tail:

Most of these attempts were to try and settle on a good face shape and style for your sona, considering the spacesuit covered most of the body

The earlier drawings have a face shape that's a little more circular, got closer to the final shape over time, and I tried to base them off of drawings you'd done

Especially happy with the one next to the laser gun sketch :)

Tenna

- Like it says in the first drawing, Tenna is something like a bulbmin (or maybe a breadbug) so he's big and scary but not necessarily hostile to regular pikmin

- He lives in a cave (probably pikmin 2 style with multiple levels, I could see him being the boss at the bottom "Lord of Screens" and his nest is in a broken tv)

- He's fairly nonaggressive but does like to collect random stuff to bring back to his nest (breadbug)

Spamton

- From the first drawing: White pikmin (used to be a red pikmin but went through a mutated candypop bulb)

- Had to give him his iconic pointy nose BUT only red pikmin have noses so (this is the bit where I thought too hard) he was originally a red pikmin but found a weird candypop bulb (colored like friend) that he went through and got turned into a white pikmin but kept his nose

- Kinda sucked at being a pikmin, never managed to get a bulb or a flower until after the candypop bulb (though he tried to fake it sometimes)

- After the candypop bulb, he couldn't return to his onion so he ended up hiding in a cave and got stuck at the bottom, where he met Tenna

- No idea how it would happen but if it did I feel like SNeo would be something like the scornet maestro (partially because all the little scornets are like his mini-spam attacks and partially because it's bird thing with a long beak sort of associated with strings and noise - in game scornet maestro has strings that it uses like a harp in its beak to control the scornets, SNeo has puppet strings and the phone with the sound wave attack) Pic for reference:
