Wow, lots of good as answers! Here's mine: right now, Kamen Rider Meteor
But I have used other pfps to represent me, but I am a little hesitant to change into something different since people are starting to associate me with the character. I would love to use something original, but I'm not an artist and I'm terrible with directions, so I wont commision anything from any artist...
I guess my main thematic is space stuff? I always wanted to be an astronaut growing up, but I gave up after watching that movie Gravity, shit's tense! And if you're disapointed that I gave up being an astronaut, don't worry, I got into college to study mechatronics engineering, so I'm still fufilling my dream in an indirect way lol.
I always liked secondary characters over the main ones, they always seem more reliable over the main character and seem to always get shit done! Reminds me of a video I watched about a character in one of the more recent seasons of Super Sentai:
TL;DR, the character stays the same trough the entire season, not because he can't change, but rather he doesn't want to change, he's perfectly content with the life he's leading... Kinda like me. Now, I won't say that I'll never change or I never changed in my life, but as of right now, I'm perfectly content with my life, I have a strong base philosophy and I'm at peace with myself and the world, I'm willing to help anyone in need because "why not?" and I'm fufilling my purpose everyday on this earth. So what I'm trying to say is: "If it ain't broke, don't fix it!"
As for another character I would associate with:
I'm also a fan of Ultraman (shocker!) and I love the character of Ultraman Hikari (again, shocker!)
He's canonically the head scientist of the Space Science Technology Bureau of The Land of Light, essentially the chief engineer of the entier planet (once again, shocker!)
Wow... This was a lenghty post, I hope I didn't bore you to death lol.
