Looking just like Ben's brand new evolved Omnitrix, this Ultimate Omnitrix fits neatly round the wrist just like a watch and features lights, sound effects and alien voices from the TV show. Attach the mini transparent figures from the 10cm Alien Collection figures (1 is included, others are sold separately) to the face of the watch to unlock the aliens' light and sound effects. Swampfire is the figure that's included.
Suitable from 4 years
Character Ben 10
