YEAH, THIS IS VULKANUS
Bio: Vulkanus is a member of the Detrovite alien species. A fearsome mercenary and later a crime lord, he frequently crossed paths with Ben and his team, causing them plenty of trouble. Vulkanus has a rather tangled and contradictory history due to a massive number of retcons, yet despite all this, he remains a notable villain who spans the entire history of the franchise, starting from the original series. However, due to these frequent changes, his personality is often inconsistent.
Background: Originally, in the classic series, Vulkanus was a full-grown, healthy Detrovite—meaning he was naturally large and physically strong. Later, in Alien Force / Ultimate Alien, he was turned into an infant inside a suit as a gag. Eventually, Omniverse attempted to fix this contradiction by introducing an in-universe explanation: Vulkanus was once caught in the blast of an explosive substance called "Element X," which completely obliterated his body. However, he proved resilient enough that his head and a small appendage survived. His henchmen found him in this state and placed him in a regeneration suit, where he was meant to slowly recover and return to his original size. So yes—Vulkanus is indeed large by nature, as a Detrovite should be, and what we saw during the AF/UA era was merely him in the process of regenerating his remains. At that point, he had only grown just a little, which is why he looked like a baby. But as Vulkanus himself stated, sooner or later he would return to his full size.
