Using his arms, you grab on to the enemies and send yourself onto them to knock them out. He can also get hurt by enemy contact and by projectiles.

Ristar is vulnerable to natural hazards like spikes and lava. He is summoned by Oruto for a wish made from the plead of the elder and the tribe of Planet Flora to save the six main planets, Planet Flora, Planet Undertow, Planet Scorch, Planet Sonata, Planet Freon and Planet Automaton and defeat the evil Kaiser Greedy and his minions to save the Valdi System. Ristar is the main protagonist of the game. Feel would go through many name and design changes (some including 'Volt' and 'Dexstar') before eventually landing on 'Ristar', an anthropomorphic shooting star with white gloves and lightning-bolt patterned shoes.

Being designed by Yuji Uekawa, this character would be known as ' Feel', who was a yellow, non-star shaped, sphere-bodied creature that would feel their surroundings. While not confirmed, it is assumed this idea was repurposed for what would become Ristar, instead being one where a character would stretch their arms in order to grab and throw objects.

This idea was rejected for the 'rolling hedgehog' idea. One of these concepts, drawn and created by Naoto Oshima, was a blue rabbit that would pick up and throw around objects using its ears. During the development of the game, Sonic The Hedgehog, SEGA held an eternal contest to create a main character for the game, and in turn, a new mascot for the company.
