Ken has very high health and attack power along with an omnistrike and a 100% chance to knockback all cat units but his multi-hit mixed with the knockback makes his damage only a third except for units with knockback immunity plus he is considered a red enemy, makes him a powerful foe on paper but really easy on practice.
Strategy
Anti red cats such as Manic islands can easily counter him along with meatshieds, in levels where he is protected you could use Long Range units like Red Riding Mina or ubers like Eva Unit-02
