The original 151 Pokemon introduced in Pokemon Red and Blue have been the subject of countless fan art over the year, including this one that imagines different forms of Voltorb based on Poke Ball types. The first Pokemon titles had various Poke Balls for capturing the many monsters that inhabited Kanto, and with more being introduced since then, one fan wanted to provide Voltorb more representation.
The Pokedex has associated Voltorb and its evolution Electrode with Poke Balls since Pokemon Red and Blue, and it's logical based on the aesthetic of the Electric-type Pokemon. As more recent Pokemon titles have introduced regional variants of existing Pokemon, Voltorb and Electrode got a proper overhaul with Pokemon Legends: Arceus as they inherited a similarly old look to the Poke Balls of the region. Inspired by such regional variants and new evolutions to old Pokemon that have been introduced to the franchise since Pokemon Red and Blue, one player has shown what other forms Voltorb may take if The Pokemon Company wanted it to look like any of the available Poke Balls.
TikTok user Mercuryballxfusions has made a series of videos focusing on their Pokemon fan art imagining Voltorb as not just a Gen 1 Poke Ball or the Pokemon Legends: Arceus equivalent. While the beginning of part one of their series may be similar to what other Pokemon fans have imagined in taking the Gen 1 color schemes and applying them to the Electric-type Pokemon effectively, Mercuryballxfusions really expands their creativity with the Lure Ball which was introduced to the series with Pokemon Gold and Silver. Other Poke Balls that Mercuryballxfusions has used as templates for their different Voltorbs include the Clone Ball, Dark Ball, Dive Ball, GS Ball, Heavy Ball, Fast Ball, and more.
Given their affinity for the Gen 1 Electric-type Pokemon and ability to draw it in many unique ways, Mercuryballxfusions seems to be a fan of Voltorb and Electrode. Going even further than creating updated Poke Ball looks for Voltorb and Electrode, Mercuryballxfusions has also done Hisuian versions of the same concept with the Old Great Ball, Heavy Ball and Feather Ball, Hisuian Jet Ball, and Origin Ball. As The Pokemon Company is known to revisit old Pokemon in its latest games like Pokemon Scarlet and Violet, it may be possible that a future title has Voltorb and Electrode that resemble one of Mercuryballxfusions' creations.
Because of the varying aesthetics provided by the multitude of Poke Balls that Mercuryballxfusions' Pokemon fan art is inspired by, Voltorb and Electrode's typing are adjusted to match similar to how some Pokemon Sword and Shield regional forms worked. Though Shiny Voltorb alters the Pokemon's look notably by swapping the red to blue, it pales in comparison to Mercuryballxfusions's Great Ball version of the Pokemon.
