Skylanders Imaginators Master Ambush Activision

Q: Does it matter if i buy a sensei that has a different element as my creation crystal or does the battle class only matter?

Sensei's are playable characters on their own. They are not tied to any of the creation crystals.

Q: Can this be used on Xbox 360?

Sorry, I can not answer this question. I am 78 yr old and I don't play the game. Our grandson playing the game and he is only 11 yr. old.

Q: Does this work with the Wii??

Yes it should work with Skylanders for Wii

Q: We have the wii and trap team/Giants/swap force portals & games. Will this work on those? They do not make imaginators game/portal for wii...

No, however the reverse is true. All the Skylanders in your collection are playable in Skylanders Imaginators. Even your old portal will work too, provided its from the same system as the game! Traps from Skylanders Trap Team will work in the racing portion of the game as they did in Skylanders Superchargers, with a Trap-compatible portal. Some in-game functionality may vary.

I do not work or am afiliated with Activision or any related products or promotions from them. THIS ANSWER IS ONLY BY MY EXPERIENCE.
