Key takeaways

Zebra-Man belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Zebra-Man to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Zebra-Man from memory before moving on to harder problems.

Fictional character biography

Jacob Baker

Jacob Baker is a high-tech scientist whose machinery irradiated his body, giving him the ability to attract and repel anything besides metal (referred to as "Diamagnetism"). He takes the name Zebra-Man, derived from the stripes covering his body. During his first fight with Zebra-Man, Batman is accidentally irradiated by the same energy and left unable to control his powers. Batman attracts Zebra-Man to himself and takes him to the Gotham City Police Department.

Kobra's Zebra-Man

When Kobra researches the origins of some of Batman's enemies and creates a strike-force called Strike Force Kobra to usurp Stagg Enterprises in his goal of world domination, one of the villains he creates is patterned after the original Zebra-Man. This version lacks the aura of the first Zebra-Man and has a mohawk that evokes the image of his equine namesake. Zebra-Man, alongside the other Strike Force Kobra members, fights the Outsiders to a draw, but Zebra-Man escapes with Elemental Woman, Planet Master, Lady Eve, and Kobra. His colleague Spectrumonster does not survive the battle while Clayface escapes. Zebra-Man appears as a member of Alexander Luthor Jr.'s Secret Society of Super Villains during the Battle of Metropolis alongside his Strike Force Kobra teammates Planet Master and Spectrumonster.

Vortex

In 2011, The New 52 rebooted the DC Universe. A version of Zebra-Man first appears as an inmate of Arkham Asylum, currently going by the moniker "Vortex". He is one of the many prisoners attempting to escape in a massive breakout attempt, which is stopped by Batman. He later appears attempting to help Catwoman escape her incarceration in the asylum, but is physically beaten by her. Vortex appears in the DC Rebirth reboot, renamed Zebra Man. This version sports short hair with black leather gloves, boots, and shorts. Zebra Man is one of the many villains taken down by Batman and Catwoman after he takes her along with him on an average night of his job. In Doomsday Clock, Vortex is seen as an inmate at Arkham Asylum at the time when Batman incarcerated Rorschach there. He protects Rorschach from the other inmates. Vortex is later seen in Zambia partaking in a card game with Fiddler, Psych, and Shrike. When Psych learns that Fiddler has cheated, Fiddler is held at gunpoint only for Psych to kill the three villains with the projections of the people they killed.

Menagerie's Zebra-Man During the "Forever Evil" storyline, a different Zebra-Man appears as a member of Cheetah's Menagerie. He is among those frozen by Killer Frost. Zebra-Man later join an Anti-Task Force X group called The Revolutionaries before joining the Suicide Squad under their new supervisor Lok.

Powers and abilities The first two incarnations of Zebra-Man possess "diamagnetism" which enables them to attract or repel all matter besides metal. Both use an inhibitor belt to control their abilities.

In other media The Jacob Baker incarnation of Zebra-Man makes non-speaking appearances in Batman: The Brave and the Bold. This version's powers can affect metal. The second incarnation of Zebra-Man appears in The Lego Batman Movie. The Jacob Baker incarnation of Zebra-Man appears in Scooby-Doo! & Batman: The Brave and the Bold.

Worked examples

Example 1 — a first encounter with Zebra-Man

Start with the simplest possible case. Write down what Zebra-Man claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Zebra-Man before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Zebra-Man ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Zebra-Man

In research: Zebra-Man appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Zebra-Man in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Zebra-Man is common in secondary-school and first-year university syllabi. It links to neighbouring topics Characters created by Bill Finger, Characters created by Mike W. Barr, Characters created by Sheldon Moldoff, so understanding it makes those chapters shorter.
In everyday life: Look for Zebra-Man outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
