This episode was terrific. It started a little silly, but when Dan meets Shun and sees Masquerade with him, things get interesting.
I thought it was cool how Shun told Masquerade that he isn't the boss of him and he battles how he wants to.
The battle itself was cool, especially after Shun realises how bad Masquerade is and so teams up with Dan to beat him and his Bakugan, Hydranoid.
This is an episode you shouldn't miss, it is probably one of the best in the whole series so far.
The ending is good as well, with Masquerade taking off swearing that Shun and Dan will lose their Bakugans into the Doom Dimension.
