Cobblemon: Iota Pokemon ι
by kazerio
Cobblemon: Iota Pokemon ι adds a rare, smaller variant of early-stage Pokémon that spawn in the Cobblemon world, with glowing eyes and a mini mark.
What it does
Iota Pokémon are a smaller, rarer version of the earliest evolution stage of each species. Only the first stage of a Pokémon line spawns as an Iota, and baby Pokémon and a few exceptions are left out. Each Iota always spawns with low HP IVs and high Speed IVs, and its glowing eyes make it easier for trainers to spot from a distance until they get close.
Iota encounters are uncommon, with roughly a 1 in 200 chance of finding one. Defeating an Iota drops items, and the mod's name refers to the Greek letter for a very small amount, which matches the size of these creatures. Their combat stats are not much different from regular Pokémon of the same species, so the difference is mostly in size, rarity and spawn behaviour.
The mod runs on the server, and players join without installing it on their side. Files are published for Fabric and NeoForge, for the single version 1.21.1, and a Data pack build is available for server platforms. The mod is released under the Creative Commons Attribution Non Commercial 4.0 license, so it is not open source.
Key features
Smaller spawn variant
Iota Pokémon are small versions of early-stage species, spawned in the world instead of as regular Pokémon.
Fixed IV profile
Each Iota spawns with low HP IVs and high Speed IVs, which sets it apart from typical wild encounters.
Glowing eyes
A constant glow on the eyes makes an Iota easier to spot until the player gets close.
Item drops and rare spawns
Defeated Iota Pokémon drop items, and they appear at about a 1 in 200 chance.
Mini mark
An Iota can carry a mini mark, which is shown on the Pokémon and can be toggled off when unequipping the mark.

How it compares
Cobblemon Alphas is a server-side mod, open source under the MIT License, for Fabric and NeoForge on 1.21.1; it adds the larger Alpha variant, the opposite of Iota. Ultimate Cobblemon Progression is open source under the MIT License and runs on client and server, covering progression rather than spawn variants. Both are on 1.21.1 like Iota Pokémon, and only Ultimate Cobblemon Progression requires the client to be installed.

What the author says
## Alphas, but smaller?! What if there was an opposite version of Alpha Pokémon? A smaller, harder to spot version? Well this is where the Iota Pokémon come in! What does Iota mean you may ask? An iota is an extremely small amount or quantity according to google, and it is one of the letters of the greek alphabets…
