🎵 Luyện Nghe Bài Hát: Ben 10 (Theme Song) - Unknown

 It started when an alien device  what it did
 And stuck itself upon his  with secrets that it hid
 Now he's got super powers, he's  ordinary kid
 He's  10.
 
 So if you see him you might be  for a big surprise,
 He'll turn into an alien before  very eyes
 He's slimy, freaky, fast and strong,  every shape and size
 He's  10
 
  with powers, he's on the case
  off evil from Earth or space
  never stop till he makes them pay
 'Cause he's the baddest kid to  save the day
 Ben 10
