Assist Pearl

Assist Pearls are a technology crafted by White Goddess to teleport to other places in the Fantendoverse. It was created after finding the blueprints for the Summoner Orb, but as soon as the god figures found out, they cursed it so it could only teleport random people, as well as making it so it broke instantly.
White Goddess would later change the function of the Pearls to trap those who opposed her. 
The Assist Pearl first debuted in Fantendo Smash Bros. Universe, where it could spawn a random character from the Doodleland series to aid opponents. The Assist Pearl returned for Fighters of Lapis/崛起的火星, Fighters of Lapis 2/โจมตีทันทีทันใด and Fighters of Lapis 3: Stargate, though would now summon a random character from various different series. After an absence, the Assist Pearl made an appearance in Fantendo Smash Bros. Contrive, where it would teleport the one who threw it to wherever it landed.
