Lex did not usually enter any one of his three forms - the Lotus form, Dragon form and Jorlam form - casually. Only faced with special obstacles or enemies would Lex enter one of his forms. Generally, there was no specific reason for this hesitation - it was just an unnecessary use of energy to stay converted.
However, ever since he had visited Regix that had changed, at least for his Dragon form. Truthfully, his Dragon form was on the verge of becoming redundant. It offered him better and stronger manipulation of laws, and it maxed out his defense, but that was all. As far as upgrades to his strength, the Jorlam form did that better, and the Lotus form's limitless energy manipulation was a unique experience on its own.
