Arguably the best reward during May is the ability to claim groupies. Groupies are randomly-generated lions that can come with special bases, mutations, and markings (they will always come with two markings randomly placed in slots 1 to 10). All groupies are heritageless, meaning they have no heritage whatsoever, similar to Newly Claimed Lionesses. They can also only be adult lionesses or adolescent males, and you are able to influence which you receive more of based on a choice you make during the storyline. You can reset this boost at any time using a Mummified Heart, purchased from Tier One of the Champion Shop.

Dude. Listen. After every Arena battle there's like shit ton of groupies, right? I could nudge some towards you sometimes. SOMETIMES, alright? It's not like I am jealous, I just don't want to be killed for trafficking or something, bro. Dude. I can get like, one groupie per 6 hours. I caaaaan't really promise it'll be a girl every time, there's a bunch of fanboys like me who would like to meet you.

By spending 8 Reputation, you can click the above button (only on Lioden during the May event, of course!) to automatically claim a groupie for you. You must have at least one territory space open—even if you end up claiming an adolescent male groupie, the script has to account for you possibly receiving an adult lioness. The groupie you claim will be directly deposited into your territory, meaning you do not have to go through a claiming process like with Newly Claimed Lionesses. You can claim one groupie every 6 hours.

• Groupies can be adult lionesses (between 3 years to 5 years of age) or adolescent males (between 1 year 1 month and 1 year 7 months of age). If you choose a specific option during the storyline, you will receive a boosted chance of claiming adolescent male groupies. This can be reversed at any time using a Mummified Heart. You only need to use a Mummified Heart once to toggle on or off the adolescent boost.
• Groupies will always come heritageless (having no heritage). Adult lioness groupies cannot be sex changed, as they lack heritage; however, adolescent male groupies can be sex changed using a Cub Sex Changer.
• Groupies can spawn with any base in the game. There is a very low chance that they will spawn with combo, rare, or special bases. Kimanjano and Mandarin are the exceptions to this, and cannot appear on groupies.
• Groupies can spawn with any eye colour in the game, including breed-only and event exclusive eye colours.
• Groupies have their own exclusive bases and eye colours that can only be achieved by claiming groupies with these bases and eye colours, or breeding to lions with these bases and eye colours.
• Groupie mane shapes are limited to Normal, Scarce, and Thick. Groupie mane colours are limited to common mane colours.
• The skins groupies are spawned with appear to be tied to their bases.
• Groupies will always spawn with two markings randomly chosen by the script. Markings will only appear in slots 1 to 10. They can spawn with any marking in the game, including special markings. Mottled Rosette, Mottled Stripes, and Tier 5 markings are the exceptions to this, and cannot appear on groupies.
• Groupies can spawn with any personality in the game.
• Female groupies have a small chance of spawning with a pose automatically equipped.
• Groupies have a very rare chance of being mutated. That being said, there are certain mutations you will never see on groupies. For ease of understanding, the potential versus restricted mutations have been listed and colour coded below.
  Potential Mutations: Achromia; Bobbed Tail; Folded Ears; Maneless; Mane Feathery; Mane Fluffy; Mane Frizzy; Mane Fuzzy; Mane Ruffled; Mane Scruffy; Mane Shaggy; Mane Silky; Mane Villous; Mane Whiskered; Melanism; Overgrown Claws; Overgrown Fur; Overgrown Teeth; Overgrown Tongue; Polycaudal; Primal; Primal Fangs; Tailless; Toothless.
  Restricted Mutations: all Lethals; all Patches and Piebalds; Blind; Dorsal Fur; Double Uterus; Dwarfism; Eyeless; Leopon; Mane Imperial; Mane Noble; Mane Succubus; Primal (Felis); Primal (Ferus); Primal (Smilus); Tigon.

If you're wondering why you would want an adolescent male for a groupie, wonder no more! There is a market for heritageless male lions, referred to as "heritage reps" or "heritage replacers". Quite a few players will stockpile adolescent male groupies during May, then sell them later on in the year once the event has ended. During November, adolescent male groupies can be sold for around 10 Gold Beetles each, with their prices fluctuating throughout the rest of the year. They are popular during November due to the tradition of new applicable mutations being released annually during Black Friday. Heritage reps are a great way to keep your pride leader's appearance, while clearing out their heritage—heritageless or "Generation One" (G1) pride leaders are extremely valued for studding!
