In original and Z-Survivor mode you see sometimes that computers have symbols or you don't have your ultimate move. That's because you need to skill up (this requires a character card). To do this you need to fill up the experience bar until you see an orange square on the radar, then go to customize. Click on your character card and then press train new skill. You have to pick a skill, and be wise about what you pick, because after you pick it it's there permanantly.
There are three type of skills move: (green) which gives you a new technique; (blue) which gives you a boost on attack, defense or action gauge; and (system) which does something to your attacks or action gauge.
When you have all blackspaces with icons you cannot skill up anymore.
