Or whatever pairing it may be, as long as the AO Alliance (a playgroup in EXVS Full Boost) are the ones playing it, it turns hilarious. Cue Unfriendly Fires, Kill Steals, and Signature Scenes being re-enacted. Here are the list of their shenanigans (aside from the example gameplay above):
Nu Gundam and Sazabi pairing here. The Sazabi player often hits Nu Gundam as it attacks the target directly, and finishing some stages wherein Nu Gundam succeeds in killing the last needed target, and it's still hit by an incoming Colony Drop attack courtesy of Sazabi.
Extreme Vs Full Boost: The Victory Gundam's primary method of attack? Launching pieces of itself at the enemy! It isn't armed with more than a beam rifle and beam saber, except for its torso and its legs, and it can keep reloading them and relaunching them again and again and again...
Lunamaria's EX Attack in Full Boost: Shinn flies in and grabs the enemy, and Luna shoots... Shinn, causing the Destiny to go nuclear while Luna apologizes profusely. No really.
One of the DLC suits has been revealed to be, of all things, the Zeta Zaku (aka Zeta Gundam with a Zaku II head from Gundam ZZ). Also, Haman Karn in an Acguy.
