Grew into a giant form by absorbing TsueTsue, Furabijo and Meemy, which was his plan all along.
Never turned into a giant and never assumed a more powerful form.
Most powerful attack is his DeathWand Kill where he charges up the Staff of the Three Philosophers with blue energy and then energy slash at the screen with maximum force which was strong enough to take out DaiVoyager in one strike.
Strongest single attacks are his lightning blast but his strongest combined attack (with his alliance) is the Earth Implosion where he combines his staff's power with all six of the other antagonists which can create an implosion in the Earth and was strong enough to destroy the Rangers's Morphing Grid.
Scheme was to use all three revived Generals to create the Staff of the Three Philosophers, a new Precious that would make him the most powerful villain of all.
Plan was to destroy the Morphing Grid and then kill the Rangers to avenge his parents. Plan did not involve the Corona Aurora and it's jewels.
