Wrench is one of Sledge's Generals and Engineer in Power Rangers: Dino Charge.
Personality
Wrench is a competent general whose passion lies in science. His versatility in science most likely won him Sledge's favor as the ship's primary mechanic and laboratory worker. Though not as passionate in battle, his fierceness is comparable to that of a machine. Most likely, he is literally a machine himself, given his exterior. When it comes to dealing with people, he'd choose his feelings however he'd like in a comparable fashion to Heckyl. However, between Heckyl and Wrench, the latter would retain his sanity. Something they do share in manipulating their own feelings is how they're prone to coming out as immature under certain situations. As one example, putting up a fearful impression during an introduction to another force, which could make the leader look horrible.
