Tobit Cromwell

Tobit Cromwell is the Green Knight, ally/6th ranger of the Mystic Knights Battle Thunder.

He is an ancestor of Tommy Oliver (who was killed in episode 1) portrayed by Jason David Frank.

Character History
At an unknown point in time, he created or found a sword and it got enchanted so when he used, he became an early version of a Power Ranger and manifested a Zord.

He debuts when the rangers face Hypnotoad as simply the Green Knight and helps the Mystic Knights defeat him, but departs when Hypnotoad regrows.

He then shows that he has the ability to become a zord himself and combine with the zord that manifested when his power was created to form the Green Knight Megazord.

In Five Rangers and Attitude, his zord can be seen combining with the other rangers zords to form the Mystic Knights Ultrazord.

He fought alongside the Time Keepers and all nine other Mystic Knights against Ivar the Boneless and his army. They were able to send Ivar back to Valhalla 4 episodes later.

He does not travel to the future to face Alex and the NEW United Alliance of Evil weather because he died or wanted to be alone again, like many of Tommy's other ancestors (White Stranger).
