An Ethernal Cub, veined with meteor light

The origin

The night the sky broke

I

It fell burning

A meteor tore through the jungle canopy and buried itself in the dark.

II

The pride drew close

Cubs crept to the glowing crater while the elders kept their distance.

III

The light chose them

It sank into their fur and never left. Their eyes have glowed since.

The mint

Every cub begins as an orb

You mint an orb. Break it open and it reveals the chest inside.

Composable by design

One cub, four billion builds

Every part is its own NFT. Equip rarer parts to raise your cub's rarity and power, then change your mind and rebuild it.

Ethernal Cubs: build your own AI Cub Ethernal Cubs (E-Cubs) are fully customizable, AI-powered NFT characters on Robinhood Chain. Open an Orb, collect random parts, assemble your Cub, and then actually talk to it, because every Cub is an AI companion. You mint a sealed Orb, not a finished Cub The mint gives you an Orb, not a completed character. That is the point of a build-your-own collection. You open the Orb at ethernalcubs.icu and it yields seven random parts, or eight from Gold upwards, which you assemble into your Cub. Orbs come in five tiers: Bronze, Silver, Gold, Diamond and Sapphire. The tier stays sealed until you open it. The Orb mints on OpenSea. 155 swappable parts, 13.25 billion combinations 155 interchangeable parts across eight categories (background, body, equipped, eyes, face, inventory, mane and tail) produce over 13,250,000,000 possible Cubs. Parts come in five rarity tiers, and named sets run across categories as chase collections. Because parts are swappable, your Cub is never locked to the way it minted, so you can keep rebuilding both its look and its combat stats. Your Cub is an AI companion Cubs are extended with Power Orbs (Memory, Creative, Knowledge, Wisdom and Vision) that unlock real abilities including longer conversational memory, creative writing, knowledge retrieval and image understanding. Cubs also battle head to head, with stats derived from the parts you equipped. Play to earn: prizes, giveaways and over $100,000 set aside Battles, tournaments, games and community events come with prizes and giveaways. More than $100,000 in NFTs and tokens across multiple chains is set aside for them around the launch, on top of the $40,000 Proud Lion Studios has already returned to its community, the $60,000 of $GUI Inu it burned, and a further $30,000 given away. A free mint you have to earn 3,333 Orbs, and no purchase price, because Ethernal Cubs is a completely free mint. But spots are earned, not open. There are four routes in: hold a Proud Lions Club NFT on Aptos, hold a GUI Lions NFT, earn a spot through community activities and games, or come through a partner collaboration. Built by Proud Lion Studios Ethernal Cubs is built by Proud Lion Studios, a UAE-registered studio in Dubai. The team launched Proud Lions Club on Ethereum in 2022 with one of the earliest fusion NFT mechanics on Ethereum, mirrored the collection to Aptos, launched GUI Lions, and has returned over $40,000 to its community through events, games and its own on-chain games.
