Okay, so allow me to explain what's going on.
This is Feral Neko's Intro. How does this work?
The rainbow-maned lion is Lionheart. At the start, he's standing behind Neko while Neko is holding up the gem called the Lion Heart. Lionheart transforms into something similar to Neko and moves towards him until Neko overlaps him. Neko flashes and both Lionheart and the Lion Heart disappear (Neko absorbed Lionheart). I've explained this in the sheet aswell and I hope my explaination is clear.
This intro is based on one of two artifacts required to fight the final boss in Super Bouncy Cat, the Phoenix. You only need one artifact and which one you have determins your form in the final battle.
The Turmoil Torus, a ring-shaped gem, grants Neko the power to become Golden Neko. The Turmoil Torus is made of the demon king's blood and grants awesome power, but amplifies the inner evil aswell. Luckily, Neko has no trace of inner evil within him. Plenty of mischief, but no evil.
The Lion Heart, a sun-shaped gem, causes Neko's inner good to manifest into the rainbow-maned lion Lionheart. Neko then rides him during the final battle. Lionheart was able to shoot rainbow lasers from his horn.
Not in the game is Neko's Goldstar form (SSJ3 rip-off). He achieves this form by absorbing the Lion Heart's power and adding Golden Neko's power to become Goldstar Neko. Since Feral Neko's Spritality involves this form, this intro seems fitting. I doubt most people will know what the f*** is going on, but is that truly necessary?
