My mech would definitely be made in a way where you can see everything inside that makes it work (think clear plastic electronics; I just love seeing how things work inside)
It would also play music from various areas - the control panel would be a piano keyboard.
As for what it would add to the super mech, it would definitely be the jukebox. I'd be making our background music in real time.

I wasn't familiar with this so I looked it up. The girl with the red hair and the machine gun looks wicked cool. So I'll take whatever she is having 😁

Something with wings :3

it's black and purple and maybe it looks kinda cool. it doesn't need capabilities, looking kinda good is enough

It's a teal colored train equipped with turrets that shoot spikey tildes, and that can send an army of roombas to slurp up all the RSS feeds in the area, allowing us to keep track of the enemy's activities

no capabilities, only complexity. sorry but your super mech now has software defined networking atop a million routing VMs

(breaks character to answer this) My part of the mech is a microwave and when attached adds deadly radiation to the atmosphere within a 10 mile radius, completely melting all enimies and allies within the vicinity. This also turns all other parts into hotdogs. >:)

Oh hell yes, I'm going to rock it oldschool and pilot a mech that looks like a robot lion! It'll offer all sorts of crazy long-range fire power, some reconnaissance capabilities, and a built-in food court that serves New York-style pizza for the crew :D

mine is a pink sheep robot and it has a beam laser that makes people be nice to each other and turns haters into dust :3

my mech is dark and gloomy and gives active camouflage and stealth and also dispenses beer and coffee to the other mechs it attaches to

its a cat and it purrs :3

I'll be the coolest grey/purple mecha ever. Wings n all. Can probably just touch you and you'd fly to Antarctica.

If I weren't in a mecha though I'd be coordinating what they do thru earpiece

A dragon prowed ship decendes from the morning star, abright in silver brilliance. Attaching to the mech.

As an arm the prow becomes a dragon maw fist as a starlight laser.

As a part of the body the prow becomes part of the helmet, the sail and oars become a cape/wings

I would be the really cool behind the scenes person. You couldn’t catch me dead in one of those things, so I’ll stay on the sidelines helping out instead..

a boombox thaat can cause 50 damage with sound waves
