Pen Pen (sometimes Pen-Pen or Pen²) is Misato's pet, a warm-water penguin, who lives in a second freezer she keeps in her apartment. She apparently took him with her when she left her previous job.

There does not seem to be a direct real-world equivalent to the species of penguin that Pen Pen is, though the closest equivalent seems to be an Erect-Crested Penguin. Pen Pen clearly possesses retractable claws (three on each "hand"), which no living bird species actually have. He also appears to have noticeably increased intelligence; watching television, reading newspapers, taking baths in hot springs, eating human food and drinking beer, and it seems to be subtly hinted that he has a near-human understanding of events around him. All of this suggests that Pen Pen is a new species, created through advanced genetic experimentation.

The manga adaptation of the series by Yoshiyuki Sadamoto (not actually set in the same continuity as the series) does provide a more in-depth explanation of Pen Pen when he is introduced. In the manga, Misato explains to Shinji that Pen Pen was created as a test animal through genetic experimentation at a research lab she used to work at. When the experiment concluded Misato adopted Pen Pen, rather than let him be euthanized.

It is never stated how long ago Misato acquired Pen Pen.

After Evangelion Unit-00 self-destructs and destroys a large swath of Tokyo-3, much of the city is evacuated. Misato sadly sends Pen Pen away from Tokyo-3 to make sure that he will be safe, sending him to live with Hikari Horaki's family.

In Rebuild of Evangelion, Pen Pen is stated as being 15 years old.

Notes

• Pen Pen is often the source of comic relief in episodes, and is often used as the (more or less) "mascot" of the series in promotional material.
• Series creator Hideaki Anno explained in an essay on his official website how the character of Pen Pen was created and named (italics are inserted info by Evapedia):

"Super straightforward naming, but I thought the repetition sounded cute. His name has officially become the 2nd power of Pen ("Pen" short for "Penguin", repeated as " Pen² "). I was reluctant at first, but we thought we needed a mascot character, so we had an animal appear in the show. As it happened, the show is set in Hakone, which is famous for its hot springs, which in turn are associated with monkeys (the Japanese Macaque monkey is famous for bathing in hot springs, such as in Hakone [1]). But that is no fun, so we decided to make it a penguin, the animal most unsuited to a hot spring. I'm positive that "hot spring penguin" was Sadamoto's idea."

• No on-screen information ever explains what function the backpack that Pen Pen wears could possibly have. It's been theorized that it has something to do with a cooling system, but that's just speculation.
• The serial number on Pen Pen's metal collar is "BX 293A"
• He makes a cameo as a bobblehead doll on Shinji's desk in Episode 26's alternate reality sequence.
