This takes me right back to Destiny 1, where for the years I played, the first character I had was an Exo Hunter who looked a lot like this, even being white. The memories of countless hours roaming random planets, grinding enemies because my connection sucked so bad I couldn't connect the Tower most of the time.

damn, old fan
I started with destiny 2 when it got ported to battle net. Was pretty addicting, even though I don't like fps

"Old" fan, I came into the Destiny scene fairly early into the first one, but not early enough to witness the apparently disastrous launch; I think I started playing right around the first DLC. I guess that's old enough, though. I played for years, pretty much mostly by myself due to my horrible connection, and my experience was boring as absolute hell because of it. Years of just running around random planets bouncing from one group of generic enemies to the next, slaughtering them all for loot. Once in a blue moon I'd be able to connect to the main hub and unleash a sea of engrams, which was always a bit hilarious. I played all the way through The Taken King and fell out right about then. I just burned out and never returned, neither to Destiny 1, nor did I ever play Destiny 2. Which is a shame, because apparently Destiny 1 had major revamps right after I left and supposedly got a real fucking story rather than the awful excuse of one it had before. Nevertheless, my memories are what they are, and a LOT of them are of an Exo Hunter who your Titan greatly resembles.

I love their exo designs and armor aesthetics a lot. Glad this scribble brought some nostalgia for you!

I created all 3 of characters as exos xd. Will upload them soon as well.

Unfortunately I have no screenshots of my Exo (on this phone, anyway), otherwise I'd post one for nostalgia sake, but just for reference, they had the same head design as Cayde, had forehead armor (much like yours, except matched the color of their head), and they were white with dark blue eyes. They also had a black, grungy splash of something on one of their eyes. I remember intending them to look like some sort of older model that had seen some years of hard combat, with retrofitted forehead plating, dingy eyes (maybe their power core was going out, or their eyes just didn't glow as bright as they used to), and a rather dirty, stained appearance. Zero idea what their outfit was, it changed so many damn times between different clothes and color schemes.

heheh awesome exo concept!
