Portal Core is a sentient AI core, story and stats are in the comments (PLAY PORTAL 2)

PORTAL REFERENCE?

Yes. It is a Portal reference

basically it's wheatley but better

Play Portal 2 if you haven't already and this boss will make more sense

This robot was made by Redi one day when he was searching the multiverse for something cool

He found an alternate version of earth where technology is way more advanced and came across a building called "Aperature Laboratories"

Redi went inside and found some very interesting things, portal guns, sentient AI, and moving platforms

There were these robots called cores which were meant to assist the main AI of the whole place, GLaDOS

Redi decided to combine all of the technology there into one core, he named it the Portal Core because it shoots portals

It also shoots lasers.

Here are the stats:

Attack damage: 1,000 - 690,000 depending on accuracy of the laser
Defense: if it turns around and uses the fan on the back it will deflect any attack that was aimed at it
Health: ∞ (DON'T WORRY; it's infinity because only certain attacks can damage it)
Speed: highest speed is 5 miles per second

The health is actually 80,000 if you have the right equipment (some attacks will do extra damage to it, example if you manage to take out its batteries it will get instant killed)

I made an animation but then I realized it'll probably give somebody a seizure

It was redi falling through two portals on the cieling and on the floor

i saw it

luckily i'm not prone to seizures :D
