Sadly i dont have some of the older ones of him on my mobile device:
I had a rough idea for Evan at 1st but he was originally for a game idea and began evolving as the game idea inproved. This affected his look, personality, abilities too. The game idea became the webcomic so his final look remained for it, but since its a comic now and i got more flexibility than a game, his costume continues to evolve (or should i say devolve XD) through the episodes.
Earlier Version, he didnt have his signature saliva powers and was actually a support character with a more serious vibe:

2d version: this is when Evan became main character he was a bit more edgy and sadistic at the time of making this. The game concept evolved drastically to involve states of matter as each character's ability. Evan's power became the ability to transform his saliva into solid matter (swords, daggers etc)
I was planning to make a 2d comic also and this would have been the style.

Finally i decided to make a 3d comic instead to keep a video-gamey vibe. He now shares the lead role alongside his brother Owen, and his former sadistic-edgyness dialed down a bit. His saliva/solid powers remain the same.
His 1st outfit in the comic is based on the previous 2-d design but its only used in the early episodes to decieve the reader that he may be emo/goth. His pants doesent remain on long (a monster ate it) and his common look throughout the early episodes is of him in his blue boxers.
decided to go for a playful, wacky, skater boy attitude.
While i dont have his other outfit completed for future episodes, this gif below shows the destruction of his 1st costume.

I updated his facial features a bit in the newer episodes. Painted little details like skin blemishes too vs the early episodes where his skin looked sorta flat.
