Description
CPU Fox, Falco, and Wolf will often abruptly cut their side specials short when recovering, and fail to make it back on the stage.
CPU Fox will spam short hop lasers when far away from another player. This allows characters with absorbing specials like Ness to easily heal critical damage, or characters with reflectors to reflect the lazers back at him to damage him.
Even in situations where the other player has recovered, CPU Falco will frequently use his down air at the edge of a stage in an edgeguarding attempt, which can be extremely hazardous and often lead to a self-destruct due to Falco's high falling speed.
When facing away from the ledge, CPU Pikachu will never use its second dash of Quick Attack and fail a possible recovery.
