STR Android #18 is a risky choice, since she would have type disadvantage, you could try using the LR Androids as friends, but they don't give any boost to your stats with their leader skill, only +4 Ki, so that would be a risky choice as well.

Just read the description of the event and bring your best team. You can tell which cards break his barrier by looking at their super attack, they made this icon just for this purpose:

Energy blasts heal him when his barrier is down, so don't super with those units after that. That's pretty much it.

And to answer your other question, here are all the stunners of the game, the cool thing about this Wikia is that it works exactly like Wikipedia. There isn't anything else I can tell you, since I have no idea what cards you own, or what team you've already tried...
