FIRST ARTFIGHT OF THE YEAR AND IT'S REVEEEEEEEEENGE!!

So, I got attacked by @sirsennohope.bsky.social , and I just HAD to get them back! Luke noticed that their boyo, Cosmos, was staring at him, and being the flirt that he is, Luke took it upon himself to help Cosmos get a proper look~

Enjoy~~

I made a space boy for Artfight! I just love sparkly freckles 😍✨
I used wispite's pause game on Tiktok to design this character.
Here is my Artfight account if you want to attack him:

(Late) Mermay 4 - Gilded Freedom (will make sense when I finish the second page lol)
Cross is having a bit of trouble writing the letters XD

#leviathantale #mermay2025
The shiver did not like that Dream brought Cross to the grotto, but Dream was able to smooth things over with them. Cross warmed up to Dust the fastest, and Dust has been teaching him mer language.

Mermay 3.5 - Free Space
This is the second page I wanted to draw for the free space. I was thinking that the prompt would either be "language barrier" or "'forced' adoption"

#leviathantale #mermay2025
Cross can't understand what Dream is saying. Dream notices that Cross is hurt, so he takes him to the abyss. Dream is saying: "Wow so handsome. Wait are you hurt? Our shiver can help. They will love you!"

Mermay 3 - Free Space
Cross has no idea what Dream is saying, since he was taken by XGaster when he was still a pup and didn't get to learn mer language (Atlantean).

#leviathantale #mermay2025
Dream is sunbathing on the reef when he notices Cross and excitedly goes to talk to him. Dream is speaking Atlantean saying, "omg another shark."

Mermay Part 2 - Sunshine Fun Time
Cross has been in XGaster's lab for so long that he forgot what the sun looks like. :')

#leviathantale #mermay2025
Cross is anxious about surviving in the wild without medical supplies, but is distracted by seeing the sun for the first time in years.

I watched the vod from Bun's KinitoPET stream, and I couldn't help but make some doodles based on some parts of it 🤣

Virux belongs to @bunrux.bsky.social
Cross voiced by @vettryce.bsky.social
Rove belongs to @smoljeanius.bsky.social
Virux wheezing at a painting of Cross labeled "Sad Painting" Rove telling Cross that he should marry Dust. Cross seems apprehensive. Cross drinking hot cocoa with Dust leaning against him. Dust teasing Cross with questions about their marriage, causing Cross to spit is drink.

Starting out with a bang lol. I decided to do a short comic for this year's Mermay. I'm going off of Sku's bingo sheet, so this prompt was Shattered Ice.

#leviathantale #mermay2025
A cargo ship crashing into ice, causing a glass tank covered by a cloth to fall off and break. Shark Cross falls out of the tank, getting tangled in the cloth.

I wanted to share the unblurred images from this, since some of them are pretty hard to see. (They were blurred because Horror doesn't remember things very clearly anymore)

This first background was very messy, but I kept it anyway, since I knew it would be blurred lol

It's always so adorable when Cross ( @vettryce.bsky.social ) talks about Dust on stream. It's also funny seeing Virux ( @bunrux.bsky.social ) asking invasive questions about their relationship lol😂

As you walk around, trying to find a way around the smoke, you realize that the smoke completely surrounds the dungeon forming a dome. There is no other way to go but to the dungeon.

I wanted to make some little doodles of my ideas for a ruxxed Cross. This is not meant to be canon! These are just my silly little ideas. :)

I was thinking XGaster would notice someone trying to take control of Cross, and fight Virux for control.

You choose to keep the mouse with you. He looks at you with disappointment in his eyes. He chose to trust you, yet you will not trust him. How cruel of you. Now that you've crushed your rodent friend's confidence, let's forget about the smoke wall.

Will you send him through the smoke?

#slaythedemon #slaytheprincess #Xtale #CrossSans
You naively put your fate in the hands of a rodent. It points to the forest, indicating that it wants you to go there. Before you can make it to the treeline, you're stopped by a wall of smoke. You are unable to pass through. Though, it seems that your rodent friend is able to pass through unhindered.

You named it Cross. How unoriginal. If you're done fawning over the local wildlife, then lets get back on track.
