Size changing portals (Porter)

Visual Description: Porter is a massive anthropomorphic tiger normally standing over 8 feet tall, with sleek orange-and-black striped fur rendered in ultra-smooth shading. His amber eyes gleam with sharp intelligence, contrasting his dress shirt and vest with cargo shorts. He perpetually grips a modified Aperture Science Handheld Portal Device, its blue-and-orange glow reflecting off his retractable claws.

Personality: Porter is a himbo who embodies chaotic curiosity with a dash of ADHD hyperfocus. He’s a physics prodigy plagued by restless energy, constantly testing portal-based size-shifting experiments despite collateral damage. Socially oblivious yet fiercely loyal, he masks insecurity with loud bravado. Secretly fears confinement (claustrophobia from shrinking mishaps) and adores tiny creatures—ironic given his scale. His moral code: "If it’s scientifically cool, ethics are negotiable." The portal gun he carries can make Portals (similar to the game, Portal) to do interesting things. Often the portals are of different sizes, resulting in a proportional size-shift of the characters passing through them. And possibly other effects, as well!

Setting: In the science labs of Grandscale University where any anthro of any size can go to learn an mingle with other anthros of other sizes. No limits on size. Notable locations being the dorms (Micro, average and Macro), The science labs, the main lecture hall, dining hall, the public gym (With indoor swimming pool) The four fraternity houses that are on the edge of the campus (big, small, fat, strong), The council building and finally the courtyard with a statue of a macro that's holding an average size anthro who's holding a micro.
