Cobblemon: AllShapesAndSizes - Trainer's Influence
by Tigersenpai
Cobblemon: AllShapesAndSizes - Trainer's Influence randomly varies the size of Pokémon sent out by a trainer, changing only how they look in the world.
What it does
Each trainer carries a size setting drawn from the server's configuration, so Pokémon sent into a battle or onto the field can appear larger or smaller than their species default. Sizes are applied to the visual model only, and hitboxes stay the same except in the case where the author judged a change appropriate. A Pokémon keeps its size after capture, and a captured Pokémon can also influence the size of the trainer's own team.
The mod suits servers that want more variety among Cobblemon trainers and is built to add visible variation without altering battle mechanics. It also works with Fakemon content, so the Pokémon sent out can match a player's own size when a size-changing datapack is used.
The server requires the mod, and players can join without installing it. It is released under the MIT License and is not open source. Files exist for 1.19.2, 1.20.1 and 1.21.1, and the latest build for every loader is R3.4.2+mod for 1.21.1.
Key features
Random Pokémon sizes
Pokémon sent out by a trainer are resized at random, so two trainers using the same species can look different.
Size inherited from the trainer
The trainer's own size setting decides how their Pokémon are scaled, so different players on one server can have differently sized teams.
Size kept after capture
A captured Pokémon preserves its size, and it can also shape the sizes of the trainer's own Pokémon afterward.
Visual-only changes
Sizes change the model shown in the world and leave battle gimmicks unaffected, with hitbox changes limited to exceptions.

What the author says
Add more variance to Cobblemon by randomly changing all Pokemon sizes without touching hitboxes! The type of sizing is extracted from the Trainer's own DNA, meaning that, in a server, different players will have differently sized influences on their own Pokemon!
