as you may already know. i released a character quite a while ago that was compatible with goku z2's beam collison. however. what you may not know is that the AI can also do a beam collison. the only reason you don't see this often is because the AI likes do use its super bar carelessly. and its also rare to have a moment when both players have 2000 power. luckly. it is quite easy to do a Beam Collison vs the AI in training mode.
The AI can also do dash collisons if you run at it with a compattable character.
it is almost impossible to beat the AI at a beam collison at max difficulty.
also: things tend to get a bit weird later though the video.....
