Masquerade is a main antagonist in the Bakugan: Battle Brawlers TV series. He is an alternate ego of Alice, created when negative energy from a Mega-dimensional Nova seeped through to Earth from Vestroia by Dr. Micheal's teleportation machine. It was the same process that turned Dr. Micheal into Hal-G.
Masquerade used Darkus Bakugan.
- He used to be the first-ranked Bakugan player before he left Alice's body. His goal is to send all Bakugan to the Doom Dimension with his Doom Card, so he can evolve his Hydranoid and have the ultimate Bakugan. He is a Darkus battler. He is revealed to be Alice in episode 38 and his origin is revealed in episode 39. Masquerade came to life when negative energy changed Alice (who doesn't know she is Masquerade or what happens when she becomes him). Darkus Hydranoid is Masquerade's guardian Bakugan. (His first guardian bakugan was Reaper, but he sent it to the doom dimension.) He battles with Dan in episode 38 and loses. After that Masquerade takes his mask off, revealing his identity, Alice.
