Ben 10 Crossover Left 4 Dead

Rampage

Francis : So you use your watch tried to had more candy that way ?

Ben : Yeah..... Not only that . Back then I'm a jerk , arrogant , stupid kid , tried to use the Omnitrix for my selfish . Grandpa Max told me use the Omnitrix to protect everyone and fight bad guy , be a hero like he did . So that is , tried to be a hero to protect everyone like you guy from danger but sometime I make mistake and I can't save everyone . People could die because of my mistake
Bill : It not your fault Ben . You did anything you could, tried to save everyone
Ben : I guess you're right
Zoey : And your Omnitrix back then when you first wear was weak then now ?

Ben : Yes , the Omnitrix I wear was weak .  When the Omnitrix timed out, it entered Recharge Mode. It would take anywhere from a few seconds to several minutes to recharge. Not only that I can only stay in Alien form about 10 minute and then transform back to human . I'm also can't switch form

Louis : I almost forget to ask . Ben ... Why your Omnitrix or Ultimatrix had a time limit ?

Ben : Recharge Mode's main purpose was to keep the Omnitrix from damaging the user. The Omnitrix would sometimes recharge instantly to protect the user from a direct physical threat.

Bill : Ben .... Can you stay in Alien form forever ?

Ben lied : No I don't think so

Ben thought : If only I had the Master Control, which offered various features, such as transforming into aliens at will, no time limit on being an alien and unlocking new aliens I never use before . And I don't have to worry about time out anymore

Francis : So Ben  what is your second story ?

Ben : My second story is Dr Animo .

Zoey : Who's Dr . Animo ?

Ben : Doctor Aloysius James Animo A.K.A Dr . Animo a mad scientist obsessed with genetic experiments on animals,  including some mutants and even unintelligent aliens

Bill : Sound like a mad man to me.

Louis : No kidding
