Kevin Levin Delta

Kevin Levin is one of the main antagonists in Delta Timeline.

Appearance
Kevin is a thin and scrawny boy with shoulder-length black hair, pale skin, and dark brown eyes, wearing a torn black T-shirt and a padlock necklace around his neck, blue jeans and black shoes with red at the bottom. In his debut, he wore an olive green jacket.

Kevin wears a brown Omnitrix-type device called the AntiTrixon his left wrist.

Kevin's padlock necklace turned out to be a tracker placed by the Forever Knight, which he later destroyed.

Personality
Kevin is a bully who seems to enjoy causing other people misery, taking sadistic joy in inflicting pain and suffering. He is also incredibly arrogant, believing himself to be better with the AntiTrix than Ben is with the Omnitrix despite having had it for a far lesser period of time, and is determined to prove this by destroying Ben. Kevin is loathed to believe that he could need help with anything, which caused him to initially reject the Forever Knight's offer of recruitment.

Despite his ruthlessness in regards to Ben, Kevin doesn't want to hurt others who aren't involved with their feud. He especially doesn't want to see Gwen getting hurt, as he has a crush on her. He has also shown a willingness to swallow his pride and work together with Ben if need be, displayed in both Franken-Fight and Four by Four.

For all his bravado, Kevin is actually quite lonely. Jealousy of Ben having friends and family that he can count on appears to be a driving force behind his hatred of him.

Powers and Abilities
Kevin seems to be remarkably smart since he was able to build the AntiTrix with home materials.[2] He also added minor modifications that make his alien forms stronger and nastier than Ben's.

Equipment
Kevin is equipped with a powerful device called the AntiTrix, a makeshift version of the Omnitrix, which can transform him into mutated versions of Ben's aliens. It also contains alien DNA that Ben Delta hasn't unlocked yet.

Weaknesses
Since he had recently created the AntiTrix he has less experience than Ben, it makes it difficult for him to fully control his transformations. Furthermore, the alterations he made to the AntiTrix makes his alien transformations unstable and unbalanced.

Kevin can be easily emotionally manipulated, as evidenced when Ben called him out for not having anyone to go back to if he fails, which ends up driving him to finally join the Forever Knight.

He can easly get angry.
