Offense
As WiIke, most of your play will be offense, so you will need to get this into your head. As said above in the overall guide intro, he has amazing range in his moves. His dair WILL be one of your most used moves, due to it's spike so you need to learn WHEN to dair, as if done wrong it will launch the opponent UPWARDS which is the exact opposite of what you will be wanting. Another offensive move is the fsmash, which is Ike's main launching move. His first jab has a reach equivalent of one Training Stage square and should NOT be ignored. A fast jab canceller can use it to deal out the pain.
