"I understand why ASGORE waited so long to hire a new royal scientist.
The previous one... Dr. Gaster.
His brilliance was irreplaceable.
However, his life... was cut short.
One day, his experiments went wrong, and...
Well, I needn't gossip.
After all, it's rude to talk about someone who's listening."

Gaster is one of the most mysterious and interesting characters in the Undertale/Deltarune series, and we're yet to fully grasp his involvement with the story, and uncover his secrets. That said, knowing what we do, and what some people have theorized I've put together my own take on the character! I hope you enjoy it.

No time for idle chit-chat though, because we need to get into toggles! This Avi has a lot of them, so brace yourself because it's gonna be sort've rapid fire from here.

Starting with clothes he has about two and a half distinct outfits that share some pieces with each other, but have overall very different vibes. From the strait-laced and stern royal scientist to the decomposing husk undone by his own experiments... he can even be a pirate :)
Let's start with the scientist look, since that's one of this avatar's more unique features!

Here he sports a white labcoat, a custom made ID badge, a pair of rubber gloves, and some stylish but functional glasses. The labcoat can be opened and closed, the bands can be removed from the sleeves, you can take off the gloves, and you can wear either of his two shirts beneath the coat.

Moving to his next outfit, we see a more game accurate look with a black coat that can also be opened and closed. It should be noted that either of his two shirts also fit beneath the black coat, and the rubber gloves can be worn beneath the sleeves- if you need to get your hands dirty!

Next with an image taken in game we see the green pirate look, you'll note that it's a retextured look for the black coat, with a hook-hand, pirate hat, neck ruffles, and of course an over-all green redeco. This look can also be used in default colors.

Past that we have our most basic look, with a comfortable knit sweater, pants that flare out towards the legs, and a pair of carefully maintained loafers. This outfit is perfect for a quiet night at the lab, or maybe to chill with a good book. The gloves can be worn over this shirt to allow for any sort of atrocities you may need to commit on the fly. Do be aware that the pants and shoes are shared between the outfits.

Last but certainly not least we have one of my favorites, a casual T-shirt for when you're feeling relaxed and lazy. Pictured on the chest are eggs, which Gaster of course loves to give out to people.

Talking about props he can actually hold, he's got a number of them!
Holdable objects include an egg- of course, a can which you can adjust the position of, a soul... because of course, a beaker of mysterious goop, and a scalpel to extract vital- well whatever you do with it.

Next I'd like to highlight the base body, because I'm very proud of how it turned out!

Here we see two pictures of Gaster's base, you'll note that his "skin" is see-through, revealing bone beneath! The top image is how it looks in blender, and the bottom shows it in game.

Next let's discuss what he leaves behind... WORLD DROPS, my favorite kind of toggle.
First and foremost we have the Determination Extractor! What does it do? I dunno! But it looks cool! You can place it along with three control panels in the world at any time. It should be noted that the control panels and the machine itself are separate toggles, so you can manipulate your wicked device from a distance.

Second for world drop toggles we have a lovely tree. You can hide behind it to give people eggs, if you want. It will occasionally drop leaves- which are sort've abstract because the tree is 8-bit.

Next we have miscellaneous toggles! Things I didn't know how to categorize!
Gaster includes his little funny cat friend

He includes a swap to make his face absolutely monstrous

He includes a handful of expressions, from a sad face to a stern look- which you've seen. He also has the ability to remove the cracks from his face for a more youthful look!

You can also remove his pupils.

Last but not least for the toggles - assuming I'm not forgetting anything, I've decided to save my two favorite things for last! Behold, a fully functional gaster blaster that you can spawn with a toggle, and fire with the squeeze of your fist! It's fully animated, including a blast charge-up and an idle.

Beyond that, he also has a set of floating hands that hover behind him and move when you speak. The man needs to be able to speak with hands, right?
Finally, as is always the case, he includes gocoloco.

I believe that's about it! I hope you like him. He's totally quest compatible!
